DO I HAVE TO USE 1/0 CABLE (3 TRIPLEX) OR 4/0 (4PLEX) FOR CALIFORNIA PGE PANEL UPGRADE? THE ONE FROM THE POLE TO MY HOUSE IS 3TRIPLEX 1/0 CABLE!! PLEASE HELP
I'm an electrical engineer but not an electrician. I've wired several houses and various projects but don't do it enough to remember all the details. These videos are great for that, especially from someone who is a professional everyday person. Everything he's done is exactly how I do it and that's refreshing knowing I'm doing it right. Funny story...my dad, also an electrical engineer, but not an electrician was wiring an addition to the house, and I was helping. I was around 12-13 and for the next 20 years thinking "white" was hot and "black" was neutral. I was changing a plug on the 2nd floor and didn't bother killing the circuit. Instead, I just remembered to NOT touch the white wire. When it came to the black wire...well, I was "shocked". An electrician friend finally clued me in. Fast forward another 10 years and while talking to my dad, I told him what my electrician friend told me. He started snickering and said he ended up going back and rewiring the addition, black to hot. Needless to say, I was "shocked" again and told him my experience asked if he didn't think it important letting me know he taught me wrong, instead of me learning the hard way? He kept snickering....
My Dad and I were always super close growing up. He was able to run his hand along an animal electric fence, I think he could even grab it? He told me it didn’t hurt. You guessed it, I trusted him, got the stuffing knocked out if me. I was so mad I didn’t want to go home
55 years in the trade as a State Licensed Journeyman Electrician / Sub Contractor and the only time that I have ever used Aluminum Wiring was for a underground feeder from the Outside 120/240 VAC 200 Amp Meter base on a Power pole to a Main Panel ! And that was a USE Triplex Direct Burial cable approved by the Power Company and AHJ . I sleeved it in 2 '' Schedule 80 PVC Conduit buried 24 '' below grade for a 50' run .
For example Main House panel to Workshop 100 amp sub panel the direct burial cable you would use is "Triplex Direct Burial"? That is only 3 lines, I do not need four like this video talks about?
I'm thinking I would have come out of that panel on the right side and relocated (2) of the circuits to the MLO panel on the left so that all of the sub panel feeders are derived from the same feeder from the main. Sad that someone would wire a sub panel without an EGC but it's rewarding to know that good electricians can identify this issue and make it right. Nice video I enjoyed watching it.
Best subpanel installation video I have seen! Thanks for all the amplifying information and shopping list. Most people at the big box stores do not provide the information.
Great video! I like how instead of you telling us what you think is correct, you have the professionals who KNOW what is correct doing the instruction! Time to go check out some of your other videos now!
This is an impressive video. Very organized and thorough and well thought out. I really like that, instead of just adding the usual "I'm not an electrician" disclaimer you actually brought a professional electrician in to do parts of the video. It's also very well filmed.
I have done Electrical 35:23 Engineering but didn't work in the field. Starting watching the video and it's helping a lot. Thank you very much. Keep up doing a good job.
Greetings - Nice video but there are some things folks need to consider. I will detail them here for your viewers. 1) The abrasion bushing is not required for use with cable, while it is above the minimums it is simply not necessary as the clamp will secure the cable in place. The bushings that are mandated via 300.4(G) or within the specific raceway articles are for abrasion while doing the install as well as after the install. Notice that 300.4(G) makes no mention of cable. 2) The use of Anti-Oxidation Paste is optional unless mandated by the manufacturer. In fact, none of the UL 67 listed panelboards require or are testing with anti-oxidant compounds. Now, that is also optional and above the minimum standards so the reason I mention this is not to let an inspector tell you otherwise. However, we at Electrical Code Academy, Inc. encourage its use. 3) You really should mention that all terminations MUST be torqued to a specific inch pound or foot pound depending on the termination size, this is part of 110.3(B) as the manufactures state these values on the labels in the cabinet but also as required in 110.14(D) as well. This is vital to the longevity of the termination due to conductor thermal expansion and contraction over time, too tight is equally as bad as too lose. 4) The panel your "electrician" is using is improperly wired as noted. However, he made a statement that he would come back and install a separate equipment grounding bus (terminal bar) but to do that he also would need to replace that SER Cable between the two enclosures since that would need to take place first before any new EGC bar was added otherwise it defeats the purpose and doesn't remove the improper case to neutral connection of 250.24(A)(5) from taking place. 5) Never use anything to "bang" in a circuit breaker. Just firm pressure as it could be a gapping issue that "banging" it in could create more issues, such as arching and poor surface contact due to gap displacement so push firm but never "BANG" it in place with the back of a hammer. Just some things for your viewers to think about......as the NEC is a minimum safety standard and going above the minimums are fine but maintaining the minimums are required. Semper Fi Soldier.
Thank you so much for this video. I'm doing a travel trailer remodel into a tiny home and we are ditching the distro panel for a breaker box so we can run more power into the unit and have full size appliances. This gives me the confidence to take the project on!!!
Kudos to you for catching the derating. Your deox isn't required on an A8000 series alloy, which all aluminum wire is required to be since the 80's. It isn't bad to use though. It is only required when reworking old actual aluminum connections. And you got the supports within a foot of the box.
I have severe ADD and usually learn by watching. I have to say this video and demonstration is so good I feel confident I could actually pull this off! Thank you for posting a great video! New subscriber ! ☺️
Thank you, watched your video twice so far and there is so much you show, exactly what needs to be done before move to the next step, always expressing safety mindfulness. Was unsure at first of switching (2)30amp double pole breakers to (2) 40 amp breakers after changing cable to (2) 8awg cables. have more confidence it is still code.
Thanks for another cool video, one thing I have to mention though is that how the sub panel is grounded is never mentioned. Yes the neutral is isolated from the box and a new ground bar is added but the box and that ground bar need to be connected to a real ground- ground bar into the earth, I.E.
Great vid, but there are a couple things that would be a great add, explain why are the breakers all on 1 side in the subpanel..(does it matter?), also what is the gauge on the wire from main to sub?, also How many breakers can you use in a sub box and how is the breaker amperage determined when choosing the breaker for the main box? Placement of the wires in the main box in terms of where does the Red hot go vs the black? …these would be great adds
Hey to answer a couple of your questions. The placement of the black or red dose not matter. With ac the polarity swaps 60 times a second(60 hz) as long as you keep the hot off the neutral bar your good
The size of sub panel is based on what ever you need. You can make it as big as the service breaker. You have 100amp coming in you can use a 100amp breaker it supply a 100 amp sub panel.
Breaker size dose not matter it is the service rating of your home. The is a calculated amount based off your square footage the size of oven and all other loads such as dryer ac and electric heat. As long as your new calculated service rating dose not go above the amps you have for your service your good.
Great video. I added a line to a QO 100amp sub box to power a GFCI and a security light and the first thing I did wrong was I got the wrong breaker. After getting the proper QO circuit breaker I was stumpped on how to wire it correctly. I was going to make the same mistake as this video. But I decided to look for a video explaining how to wire a the circuit breaker to the sub box. After looking for a half day on RUclips and Google. I found your video And it is the most extensive of all the videos on RUclips. Tomorrow I will be finishing the circuit breaker install. Thank you
SER wire with an SEU connector. My local inspector would not be happy lol Love the videos and glad I found them. You guys are doing right! Hope your inspections are smooth. Here in New England they can be hard core!
Thank you for consolidating all of this information into a very professionally made video. I will have to be doing this installation soon, and this reference seems to be a good trustworthy one-stop-shop. As a courtesy for your efforts, I've also liked, subscribed, and clicked the bell for your channel. Thank you
i am now in a program to learn to become an electrician's apprentice. When ever I mention to my instructor (an old school electrician about the work in my house that I have done (including wiring a sub panel in my walk up attic) and that I have learned of a few things I could have done better, she reminds me that should only do work under a certified electrician. So I do appreciate that you discussed at least pulling a permit for things like the sub panel. The one thing that I think was bad though was the guy with the beard in the beginning who indicated that even if you don't know anything about being an electrician, this video will help you be able to do the job yourself. If you were to remake this tutorial, I recommend not saying that, and constantly reminded people to always work with the power off at the source, and then to check with a voltmeter at the new sub panel that there is indeed not power coming into it. Good mellow instructions though.
Be very careful sir. Insurance companies can withhold payments in the event of an electrical caused disaster if the legal paperwork (permits/inspections) are not done correctly. It might be possible for the legal payout to fall on the person that did the work along with the knowledge that your work may have injured someone. See if you can get your instructor to talk on that subject for a few minutes. That talk may save you and your classmates more than just money. Thanks.
Finally, a video that actually shows how to do this without leaving out pertinent information or videos that contradict and confuse in the same damn video. I would guess if Google actually wanted t censor content for the safety of people watching, THIS would be the appropriate topic. I would hazard a guess that >90% of "sub panel" videos would be removed. Semper fi brother, but my chevrons had rifles not hammers there Devi Dog!
I like your video. I put labels directly on the circuit breakers so I know which breakers are which even when the cover is off. (It only took me 20 years to figure that out!)
Pretty reasonable demonstration. A few comments: - I don't like all the extra RX inside the boxes - I usually get a length and cut back the RX THEN insert it into the panel or box so you're not reaching in trying to clip that stuff off in the back of a box. - Could have covered a few other things like how close staples need to be on the cable after exiting the box (a box that does not have internal clamps). - I also never liked putting more than one RX under a single clamp - I know its done all the time - but if I have the space - each run gets its own or I use the double clamps.
You're in my hood! I recognized this Lowes and the Lex Athletic Club as soon as it panned through. +1 sub - looking to put in a sub panel soon, thanks for all the info!
Dude your video is amazing. I just saw it and you give practically all the info: what you can do and what you can not do according to the NEC. Thank you
Quality Training! This is how it should be done! If I may, I would have liked to see a quick visual Matrix to show how to properly de-rate the cable if wanting an 80/100 Amp breaker. Subscribed!
James, I followed 2020 NEC from 310.14.(A).(3). To annex B and only found references to outside the NEC. I suspect his advice is both accurate and conservative and like you, would love to see a chart or way to calculate this. I suspect something use to be in the code books. If you find anything please let me know.
Great info, great video, everything is here...to see and learn. you don't have to search any further and watch any others just come up with missing info.
Absolute amazing video, lot of information and well explained, I’m impressed, I looked everywhere to find information about this. I’m very grateful. Thank you do much.
I'm a Master Electrician and started my apprenticeship in 1984. I'm pleased to see "my replacements" are being taught well and have pride in what they do! Keep up the great work! BTW , my clients are happy to pay for quality work. Don't let the naysayers dissuade you from doing your best!
Details so amazing. Best video on wire a sub panel. We are diving into an EV car(specially Tesla) and you should do a video on how to install a NEMA 14-50 outlet and also how to install a Tesla wall charger. You will have much more viewers and followers.
@@SgtDonovan They are many in here already but not that good, after I watched your RUclips and I knew that your will be much better than other out there.
SgtDonovan; you are doing a very good instruction and installation for you viewers excellent job. I couldn't get a better education in trade school thanks.
Lol I didn't catch that the first time watching. Me personally I use a robertson/square bit for real good torque but specs on receps arnt high like 15 to 20 ft pounds so it doesn't take much. Over tourquing is a thing btw and can damage conductors.
Really liked your video. I learned a lot. I saw that there is a maximum height for the sub panel box, is the a minimum height for the box? Thanks for your help.
Thank you my friend very well done you are a great teacher I will be installing 100-amp subpanel which will be 60 feet from the main panel any suggestion related to wire how many breakers does,or advisable for panel box 100 amp in your opinion. I hope something good happen for you today
Excellent info. One point of contention: Think hard about whether you might expand the service (eg add circuits & more load).With the price of electrical supplies skyrocketing, its not so smart to just oversize stuff. In my first house (600 sq ft cottage), we used 12 ga romex and 20 amp breakers for outlets even though 14 ga & 15 amp was standard. I never used any of the extra capacity so it was really just a waste of money. We also put in a 200 amp panel but 100 amp would have been more than enough for my little cottage.
Ok, but now you sell, the next guy adds on, and you made it easy on him, or you decide to add on yourself later. Oversizing is almost always a good idea as long as you don't make it ridiculous. Case in point, the electrician in this video is adding a subpanel to a subpanel; if the guy had oversized by just a little, he wouldn't be hiring a second electrician to put in a third panel.
Also, a 200 amp service adds value to your home over a 100 amp service. When you going to sell a home, people are looking for a maximum sized panel with extra available circuits.
By the NEC 2020 Code , ALL 120 VAC 15 & 20 Amp branch circuits are to be on AFCI Breakers ! And if it's for Outside Receptacles , Garage Receptacles , Kitchen Receptacles and Bathroom receptacles , has to be on Combination AFCI & GFCI Breakers !!
This is a very well done video, I love the Shopping List you provided and the detail you put into making this Amazing video...Thank you! You have earned my Subscription.
@8:04 Square D, and probably others, require you to remove 3 screws from the ground bar to install the lug adapter to ensure the full length of the lug is in contact with thr ground bar.
Always wear gloves and tape all of your screwdrivers to the hilt. And NEVER PILE TOOLS BELOW THE BUSS BAR IN A HOT PANEL..... BOOM.....you'll thank me!!!!
Sgt D. Thanks for the 411. Ssg Hall (82nd) is greatful. I O U a box of brand new crayons. Again. I am learning this new. I only know Aviation DC and Automotive DC from the Army. I am working hard to learn how to do this correctly to put electricity in my new LARGE shed 100ft from my house. I am watching a lot of videos, yours is very good friend. Semper Fi brother, thank you for the help. :D
Get yourself an NEC book and keyword finder and seems like now days you dont need schooling anymore to install electrical. All the things i learned in school i can find in YT now
I live in New England and the guidance here is good. Where I diverge is that this work should be done by someone who is licensed. We have to work as apprentices for some time before we can do this type of work. There are many variables that can make it a hazardous installation if you are inexperienced. At minimum all the mains should be torqued to spec as well as branch circuits. Is the average handy guy so equipped? Just saying. Personally I would have used a MLO load center.
Yes very informative instructions, I couldn’t help notice how that guy running the electrical wiring sounds just like the doctor on that movie “The Thing” with Kurt Russell in it, 😅 bro you sound just like him
2 things - Current NEC code requires almost ALL accessible outlets to be fed by GFCI type breakers, there are some exceptions, so check with the local inspector (the box store employee is not one). Next, the distance from the source panel to the sub needs to be taken into account in sizing the feed conductor, this is due to voltage drop under load - in this case 'bigger is better, but don't overdo it!
A note of clarification would be that the accessible outlets (receptacles) referenced that need GFCI protection would include kitchen, outside a home, garage, bathrooms, wet bars, utility sinks, etc., and unfinished areas in a basement. Hopefully we’re not forgetting any areas. Thanks Jeff and Jason
Great video! Very clear, love the context and reasons for, details. some additional detail for a garage sub panel to install multiple 240v outlets is what im looking for. Washer dryer circuit, 220amp welder and perhaps another for mobility. Will a standard sub like in your vid work? What are the wiring reqs and is the run similar to a 110v outlet or would you want the washer on a separate circuit while the welder and other outlets are on the same?
Great video! I see that you used aluminum wiring. Do you need to add the antioxidant when using copper wire? Also, I need to add a sub panel in my house but the main panel is rated at 100 amps and is full. Can a 80 or 100 amp sub panel be added as I require a 220 volt circuits and 20 amp outlets for operating tools and equipment?
Well if you watched the video it says only needed with aluminum because copper can't be used. If you have to ask questions that are already answered you should prob hire someone this is dangerous if you aren't fully aware.
No you don’t use it on copper it won’t hurt but Just not needed. Also per code it’s not needed on the newer aluminum wire any more we use now days. It was needed for old school aluminum because it would heat up, but the stuff we use today is not pure aluminum so per code it’s not needed. But I do recommend it because it can help with corrosion especially if you live near the ocean like Florida or Cali …
Antioxidant isn't required on copper wire because even when it oxidizes, it does not lose any of it's conductivity. It's not even needed for Aluminum (AA-8000) but it doesn't hurt to use it. You can add a subpanel of any size since you'll be restricted by the breaker at the main panel. You can go with 100A for the subpanel but if your main is already full and you think it's not enough, would be best to upgrade to a 200A service.
Great video as usual, regarding installing a 50a breaker on my sub panel and specifically capcity. I have a new Tesla and want to add a 50a breaker on my garage 100a sub panel. Can you confirm that this is no-no please?
Mannn!! I love this video! I really appreciate how you put it together and why you did it that way. I can relate so much, brother. Too real! This is the hands down best tutorial. You’ve got another subscriber. #salute
I also must say as an electrician the first and most important thing you should do with ANY electrical distribution system is make sure all factory screws are to torque specs. At the very very least not loose. I can't tell you how many times a issue had arised from such issues.
@@outsidethebox6986 yes, all the ground wires should connect back to "earth ground" (ground rod or equal). Grounds and neutrals should only connect electrically at the service entrance point. How many individual circuit ground wires under one screw should be delineated in the box instructions. In the electrical industry everything is rated and approved in some way so 2 or 3 under one screw may not be allowed.
I'm not an electrician, but I am a retired mechanic. I ALWAYS torque the lugs and the fasteners. The cost of a torque wrench is substantially cheaper than the deductible when your loose connector results in a fire.
I need to install a 100 amp sub panel that's going about 175 feet from my house. I know I need feeder wire and was thinking about using aluminum wire but I keep getting conflicting information. Some say I need 2/0 aluminum feeder and some say 4/0 aluminum feeder. What would you recommend and should I just not be cheap and go with copper wire and if so what size? If you can give me any advice I would deeply appreciate you and it would be a blessing. Thank you and great video.
Thanks for your video. I truly appreciate it, but I am one of those people who feel like something is missing. From the beginning when you started to doing the subpanel I didn’t see where the 4 wire came from or how it’s connected to the main box.
Thanks for the helpful video, around how much would it cost to supply all the components, how much am I looking to spend in total more or less? Thank you
Great video thank you for your Service…Do you have any videos on installing a electric sub panel out doors or running electric from main to pool equipment
On wiring the GFCI Outlet, he used the holes to slide the wires in, then tightened them down, rather than using the "hook" method. Most every other video I have watched on the subject, they recommend the "hook" method for safety. What do you think of one vs the other? Great video. Thanks.
As an electrician either way is good. It's not like it's a back stab those connections are poorly made but the one here have a pressure plate and make a good solid connection. But to each there own sometimes it's just preference.
when applying anti oxidants read instructions if using nolux i believe you use a wire brush to lightin brush the aluminum following grain then apply some nolux with a brush then a little on the around the lug opening and then push the wire through and torque to spec
Very informative video. Thank your for sharing your knowledge. Question: In your video, you run a 4-wire cable from one subpanel to another subpanel. I take it that doing that is OK. Am I right?
You ain't gonna' teach me a damn thing !! I'm a State Licensed Journeyman Electrician / Sub Contractor with over 55 years in the trade and I have had a lot more schooling , classes and work experience in the trade than you will ever have !!
Why are you applying anti-ox compound? Its not required by the NEC, or the the wire MFG or the panel/lug MFG, and the wire does not oxidize unless your using wire from pre-1980. In the section of the video about connecting the sub panel to the main panel; It was said to add a grounding bar and move all the grounding wires to the bar. It should be noted, the grounding conductor coming into the panel as to be added first or it will be and ungrounded system. Torqueing per the MFG instruction and the NEC was also missed.
Very helpful and information. Buy why did he put a GFCI outlet on a GFCI breaker? Isn't the idea of a GFCI breaker that you don't have to buy expensive GFCI outlets to attach to them? Also, since that was a 20 amp breaker, shouldn't the outlet have a little horizontal slot to indicate that it is 20 amps visually?
I feel as though I can trust this information. That means a lot. Semper Fi
You can. He catches details like derating the SER because its a feeder and securing the romex within 1 foot of the panel that most electricians I know miss.

Great electrical instructions. Very precise and easy to understand and especially without dumb music in the background.
I recommend hooking up the sub feed last. It makes installing the other wires much easier.
Easier and much safer. No lock out required

Thank you, watched your video twice so far and there is so much you show, exactly what needs to be done before move to the next step, always expressing safety mindfulness. Was unsure at first of switching (2)30amp double pole breakers to (2) 40 amp breakers after changing cable to (2) 8awg cables. have more confidence it is still code.
Thanks for another cool video, one thing I have to mention though is that how the sub panel is grounded is never mentioned. Yes the neutral is isolated from the box and a new ground bar is added but the box and that ground bar need to be connected to a real ground- ground bar into the earth, I.E.
Great vid, but there are a couple things that would be a great add, explain why are the breakers all on 1 side in the subpanel..(does it matter?), also what is the gauge on the wire from main to sub?, also How many breakers can you use in a sub box and how is the breaker amperage determined when choosing the breaker for the main box? Placement of the wires in the main box in terms of where does the Red hot go vs the black? …these would be great adds
Hey to answer a couple of your questions. The placement of the black or red dose not matter. With ac the polarity swaps 60 times a second(60 hz) as long as you keep the hot off the neutral bar your good
The side or location of breakers do not matter you can put them in any order.
The size of sub panel is based on what ever you need. You can make it as big as the service breaker. You have 100amp coming in you can use a 100amp breaker it supply a 100 amp sub panel.
Breaker size dose not matter it is the service rating of your home. The is a calculated amount based off your square footage the size of oven and all other loads such as dryer ac and electric heat. As long as your new calculated service rating dose not go above the amps you have for your service your good.
The gage of wire is based on the size of your service going in.100 amp sub panel will need a larger wire than a 60 amp sub panel.
Thanks for making this video, it was just what I needed to see how to wire a sub panel in my garage!!!!!!!! Great job !!!!!!!!!
This is an AMAZING amount of material... you should be an instructor! SO well done!
Great video. I added a line to a QO 100amp sub box to power a GFCI and a security light and the first thing I did wrong was I got the wrong breaker.
After getting the proper QO circuit breaker I was stumpped on how to wire it correctly.
I was going to make the same mistake as this video. But I decided to look for a video explaining how to wire a the circuit breaker to the sub box.
After looking for a half day on RUclips and Google.
I found your video And it is the most extensive of all the videos on RUclips.
Tomorrow I will be finishing the circuit breaker install. Thank you
SER wire with an SEU connector. My local inspector would not be happy lol
Love the videos and glad I found them. You guys are doing right!
Hope your inspections are smooth. Here in New England they can be hard core!
Where do you find the 200 amp set connector
Thank you for consolidating all of this information into a very professionally made video. I will have to be doing this installation soon, and this reference seems to be a good trustworthy one-stop-shop. As a courtesy for your efforts, I've also liked, subscribed, and clicked the bell for your channel. Thank you

i am now in a program to learn to become an electrician's apprentice. When ever I mention to my instructor (an old school electrician about the work in my house that I have done (including wiring a sub panel in my walk up attic) and that I have learned of a few things I could have done better, she reminds me that should only do work under a certified electrician. So I do appreciate that you discussed at least pulling a permit for things like the sub panel. The one thing that I think was bad though was the guy with the beard in the beginning who indicated that even if you don't know anything about being an electrician, this video will help you be able to do the job yourself. If you were to remake this tutorial, I recommend not saying that, and constantly reminded people to always work with the power off at the source, and then to check with a voltmeter at the new sub panel that there is indeed not power coming into it. Good mellow instructions though.
I hear you.. -guy with beard
Be very careful sir. Insurance companies can withhold payments in the event of an electrical caused disaster if the legal paperwork (permits/inspections) are not done correctly. It might be possible for the legal payout to fall on the person that did the work along with the knowledge that your work may have injured someone.
See if you can get your instructor to talk on that subject for a few minutes. That talk may save you and your classmates more than just money.
Thanks.
Finally, a video that actually shows how to do this without leaving out pertinent information or videos that contradict and confuse in the same damn video. I would guess if Google actually wanted t censor content for the safety of people watching, THIS would be the appropriate topic. I would hazard a guess that >90% of "sub panel" videos would be removed. Semper fi brother, but my chevrons had rifles not hammers there Devi Dog!
I always strip the jacket off conductors , romex and feeders nice and square, them feed them into the connector clamp, makes a more professional look!
I like your video. I put labels directly on the circuit breakers so I know which breakers are which even when the cover is off. (It only took me 20 years to figure that out!)
Pretty reasonable demonstration.
A few comments:
- I don't like all the extra RX inside the boxes - I usually get a length and cut back the RX THEN insert it into the panel or box so you're not reaching in trying to clip that stuff off in the back of a box.
- Could have covered a few other things like how close staples need to be on the cable after exiting the box (a box that does not have internal clamps).
- I also never liked putting more than one RX under a single clamp - I know its done all the time - but if I have the space - each run gets its own or I use the double clamps.
I appreciate the feedback and tips. I especially appreciate how you were respectful and kind!
Nice video. My suggestion is to use insulated staples, and also to have a torque wrench for use on lugs with torque spec requirements in the panels.
I just love the use of a torque driver on the connections.
A lot of great info being presented in a way that is very easy to understand. Well done.
You're in my hood! I recognized this Lowes and the Lex Athletic Club as soon as it panned through. +1 sub - looking to put in a sub panel soon, thanks for all the info!
Good eye!
Dude your video is amazing. I just saw it and you give practically all the info: what you can do and what you can not do according to the NEC. Thank you
Quality Training! This is how it should be done!
If I may, I would have liked to see a quick visual Matrix to show how to properly de-rate the cable if wanting an 80/100 Amp breaker.

James, I followed 2020 NEC from 310.14.(A).(3). To annex B and only found references to outside the NEC. I suspect his advice is both accurate and conservative and like you, would love to see a chart or way to calculate this. I suspect something use to be in the code books. If you find anything please let me know.
Great info, great video, everything is here...to see and learn. you don't have to search any further and watch any others just come up with missing info.
Absolute amazing video, lot of information and well explained, I’m impressed, I looked everywhere to find information about this. I’m very grateful.
Thank you do much.
Most underated electrical video
Thanks for the information. Love the channel. Wish I could’ve seen how you powered the sub-panel.
I'm a Master Electrician and started my apprenticeship in 1984. I'm pleased to see "my replacements" are being taught well and have pride in what they do! Keep up the great work!
BTW , my clients are happy to pay for quality work. Don't let the naysayers dissuade you from doing your best!
Details so amazing. Best video on wire a sub panel. We are diving into an EV car(specially Tesla) and you should do a video on how to install a NEMA 14-50 outlet and also how to install a Tesla wall charger. You will have much more viewers and followers.
Great idea! Thanks!
@@SgtDonovan They are many in here already but not that good, after I watched your RUclips and I knew that your will be much better than other out there.
Hey man. This is really nice of you. This took some effort. I can tell you always put the best foot forward.
SgtDonovan; you are doing a very good instruction and installation for you viewers excellent job. I couldn't get a better education in trade school thanks.
Excellent video! However, at 32:40, I do think the Electrician needs a longer screwdriver, to tighten the terminals on the GFCI receptacle.
Lol I didn't catch that the first time watching. Me personally I use a robertson/square bit for real good torque but specs on receps arnt high like 15 to 20 ft pounds so it doesn't take much. Over tourquing is a thing btw and can damage conductors.
I wish I would have watched this video first! Very well done!
Really liked your video. I learned a lot. I saw that there is a maximum height for the sub panel box, is the a minimum height for the box? Thanks for your help.
This is an amazing tutorial. Thank you for all the thought and work you put into this it really helped.
Thanks!
Thank you my friend very well done you are a great teacher I will be installing 100-amp subpanel which will be 60 feet from the main panel any suggestion related to wire how many breakers does,or advisable for panel box 100 amp in your opinion.
I hope something good happen for you today
Excellent info. One point of contention: Think hard about whether you might expand the service (eg add circuits & more load).With the price of electrical supplies skyrocketing, its not so smart to just oversize stuff. In my first house (600 sq ft cottage), we used 12 ga romex and 20 amp breakers for outlets even though 14 ga & 15 amp was standard. I never used any of the extra capacity so it was really just a waste of money. We also put in a 200 amp panel but 100 amp would have been more than enough for my little cottage.
Ok, but now you sell, the next guy adds on, and you made it easy on him, or you decide to add on yourself later. Oversizing is almost always a good idea as long as you don't make it ridiculous. Case in point, the electrician in this video is adding a subpanel to a subpanel; if the guy had oversized by just a little, he wouldn't be hiring a second electrician to put in a third panel.
@@vaeshethblade931 absolutely.
Also, a 200 amp service adds value to your home over a 100 amp service. When you going to sell a home, people are looking for a maximum sized panel with extra available circuits.
I think it makes sense to oversize the panel but not the circuits.
Nice. Should have watched this before I blew the main 200 amp breaker with panel screw touching a cable.
By the NEC 2020 Code , ALL 120 VAC 15 & 20 Amp branch circuits are to be on AFCI Breakers ! And if it's for Outside Receptacles , Garage Receptacles , Kitchen Receptacles and Bathroom receptacles , has to be on Combination AFCI & GFCI Breakers !!
Not exactly but okay
@@electricaf365 ; Yes, EXACTLY because it is CODE !!!!
@@electricaf365I was worried this was true, can you explain why it isn't?
This is a very well done video, I love the Shopping List you provided and the detail you put into making this Amazing video...Thank you! You have earned my Subscription.
@8:04 Square D, and probably others, require you to remove 3 screws from the ground bar to install the lug adapter to ensure the full length of the lug is in contact with thr ground bar.
Excellent video explaining sub panels, wire sizing, etc. I am curious as to why you installed a 15 amp GFCI receptacle on the 20 A circuit.
Excellent tutorial and I learned something even I’m not an electrician 👍
Always wear gloves and tape all of your screwdrivers to the hilt. And NEVER PILE TOOLS BELOW THE BUSS BAR IN A HOT PANEL.....
BOOM.....you'll thank me!!!!
That’s an amazing teaching. I think I know how to do it by watch once of this video
Great video..accurate and informative description for the novice do-it-yourselfer would like to see more for different type panels..
helpful. might do this for the suite in my house so the tenants can access the breakers if they pop one.
Sgt D. Thanks for the 411. Ssg Hall (82nd) is greatful. I O U a box of brand new crayons.
Again. I am learning this new. I only know Aviation DC and Automotive DC from the Army. I am working hard to learn how to do this correctly to put electricity in my new LARGE shed 100ft from my house. I am watching a lot of videos, yours is very good friend. Semper Fi brother, thank you for the help. :D
I am a retired I.B.E.W. electrician and a former Marine Corporal, Semper Fi. 75 to 79
I also am a retired electrician and former Marine Corporal, 76 - 79, Semper Fi !!
No idea what your other vids are, but I sub'd because I want to see them!!! Thanks!
Get yourself an NEC book and keyword finder and seems like now days you dont need schooling anymore to install electrical. All the things i learned in school i can find in YT now
idk why I watch these videos even though I'm an electrician and already know all of this lol.
Because wise people(like you) realize they can always learn something new. or a better way to do something.
#LifelongLearning
Thing is, CAN you always see the mistakes made by others? The NEC has its merits, NOT ALL
ELECTRICAL WORK IS DONE
"CORRECTLY!!!!"
I like this video. It's explanations are simple and logical to remember.
I live in New England and the guidance here is good. Where I diverge is that this work should be done by someone who is licensed. We have to work as apprentices for some time before we can do this type of work. There are many variables that can make it a hazardous installation if you are inexperienced. At minimum all the mains should be torqued to spec as well as branch circuits. Is the average handy guy so equipped? Just saying. Personally I would have used a MLO load center.
I'm not an electrician, but I noticed that as well. Torque matters.
Thank you for your insight brother... I fly drones also... Just ran in 17.75k Quantico March 25th
Subscribed and liked to support a fellow veteran!
Yes very informative instructions, I couldn’t help notice how that guy running the electrical wiring sounds just like the doctor on that movie “The Thing” with Kurt Russell in it, 😅 bro you sound just like him
What a GD great channel! Sub. Excellent work. Your monologue was like it was for me personally. Imma a 15 vet . SF!!
2 things - Current NEC code requires almost ALL accessible outlets to be fed by GFCI type breakers, there are some exceptions, so check with the local inspector (the box store employee is not one). Next, the distance from the source panel to the sub needs to be taken into account in sizing the feed conductor, this is due to voltage drop under load - in this case 'bigger is better, but don't overdo it!
A note of clarification would be that the accessible outlets (receptacles) referenced that need GFCI protection would include kitchen, outside a home, garage, bathrooms, wet bars, utility sinks, etc., and unfinished areas in a basement. Hopefully we’re not forgetting any areas. Thanks Jeff and Jason
WRONG
No code ever anyplace in the history of ever has required nor does require almost all outlets to be a gfi or gfi protected.
@@lloydmills9619 he did not say GFI.....he CFCI and yes they are required CFCI breakers not outlets
The NEC and the English language are first cousins. Always an exception to the rule. 🤭🤭🤭
Excellent work and demonstration Gents. Thank you
Fantastic video Sarge thank you for the info thank you to your guests great information
Great video! Very clear, love the context and reasons for, details. some additional detail for a garage sub panel to install multiple 240v outlets is what im looking for. Washer dryer circuit, 220amp welder and perhaps another for mobility. Will a standard sub like in your vid work? What are the wiring reqs and is the run similar to a 110v outlet or would you want the washer on a separate circuit while the welder and other outlets are on the same?
oh thank god. slow and precise. worth every second. thank you!!!
Great video! I see that you used aluminum wiring. Do you need to add the antioxidant when using copper wire? Also, I need to add a sub panel in my house but the main panel is rated at 100 amps and is full. Can a 80 or 100 amp sub panel be added as I require a 220 volt circuits and 20 amp outlets for operating tools and equipment?
Well if you watched the video it says only needed with aluminum because copper can't be used. If you have to ask questions that are already answered you should prob hire someone this is dangerous if you aren't fully aware.
No you don’t use it on copper it won’t hurt but Just not needed. Also per code it’s not needed on the newer aluminum wire any more we use now days. It was needed for old school aluminum because it would heat up, but the stuff we use today is not pure aluminum so per code it’s not needed. But I do recommend it because it can help with corrosion especially if you live near the ocean like Florida or Cali …
Antioxidant isn't required on copper wire because even when it oxidizes, it does not lose any of it's conductivity. It's not even needed for Aluminum (AA-8000) but it doesn't hurt to use it. You can add a subpanel of any size since you'll be restricted by the breaker at the main panel. You can go with 100A for the subpanel but if your main is already full and you think it's not enough, would be best to upgrade to a 200A service.
Great video as usual, regarding installing a 50a breaker on my sub panel and specifically capcity. I have a new Tesla and want to add a 50a breaker on my garage 100a sub panel. Can you confirm that this is no-no please?
Mannn!! I love this video! I really appreciate how you put it together and why you did it that way. I can relate so much, brother. Too real! This is the hands down best tutorial. You’ve got another subscriber. #salute
Thanks so much!
I also must say as an electrician the first and most important thing you should do with ANY electrical distribution system is make sure all factory screws are to torque specs. At the very very least not loose. I can't tell you how many times a issue had arised from such issues.
Is it okay to connect all the ground wires togher on the ground bar.
@@outsidethebox6986 yes, all the ground wires should connect back to "earth ground" (ground rod or equal).
Grounds and neutrals should only connect electrically at the service entrance point.
How many individual circuit ground wires under one screw should be delineated in the box instructions. In the electrical industry everything is rated and approved in some way so 2 or 3 under one screw may not be allowed.
I'm not an electrician, but I am a retired mechanic. I ALWAYS torque the lugs and the fasteners. The cost of a torque wrench is substantially cheaper than the deductible when your loose connector results in a fire.
I need to install a 100 amp sub panel that's going about 175 feet from my house. I know I need feeder wire and was thinking about using aluminum wire but I keep getting conflicting information. Some say I need 2/0 aluminum feeder and some say 4/0 aluminum feeder. What would you recommend and should I just not be cheap and go with copper wire and if so what size? If you can give me any advice I would deeply appreciate you and it would be a blessing. Thank you and great video.
Thanks for your video. I truly appreciate it, but I am one of those people who feel like something is missing. From the beginning when you started to doing the subpanel I didn’t see where the 4 wire came from or how it’s connected to the main box.
Thanks for the helpful video, around how much would it cost to supply all the components, how much am I looking to spend in total more or less? Thank you
Great video thank you for your Service…Do you have any videos on installing a electric sub panel out doors or running electric from main to pool equipment
On wiring the GFCI Outlet, he used the holes to slide the wires in, then tightened them down, rather than using the "hook" method. Most every other video I have watched on the subject, they recommend the "hook" method for safety. What do you think of one vs the other? Great video. Thanks.
As an electrician either way is good. It's not like it's a back stab those connections are poorly made but the one here have a pressure plate and make a good solid connection. But to each there own sometimes it's just preference.
when applying anti oxidants read instructions if using nolux i believe you use a wire brush to lightin brush the aluminum following grain then apply some nolux with a brush then a little on the around the lug opening and then push the wire through and torque to spec
This the best video I have seen by far ty
This video is the video I should’ve watched a long time ago
I don't need an electrician after watching that.
Exactly what I was looking for. Great tutorial! Thank you
Very informative video. Thank your for sharing your knowledge.
Question: In your video, you run a 4-wire cable from one subpanel to another subpanel. I take it that doing that is OK. Am I right?
Very Educational & Informative!
Learned a bunch from this video. Thanks for sharing this.
You ain't gonna' teach me a damn thing !! I'm a State Licensed Journeyman Electrician / Sub Contractor with over 55 years in the trade and I have had a lot more schooling , classes and work experience in the trade than you will ever have !!
Why are you applying anti-ox compound? Its not required by the NEC, or the the wire MFG or the panel/lug MFG, and the wire does not oxidize unless your using wire from pre-1980.
In the section of the video about connecting the sub panel to the main panel; It was said to add a grounding bar and move all the grounding wires to the bar. It should be noted, the grounding conductor coming into the panel as to be added first or it will be and ungrounded system.
Torqueing per the MFG instruction and the NEC was also missed.
I can appreciate your level of OCD!
¡Semper Utile!
Very helpful and information. Buy why did he put a GFCI outlet on a GFCI breaker? Isn't the idea of a GFCI breaker that you don't have to buy expensive GFCI outlets to attach to them? Also, since that was a 20 amp breaker, shouldn't the outlet have a little horizontal slot to indicate that it is 20 amps visually?
