he is the best i have seen at teaching electrical. he explains everything so thoroughly and gives all kinds of examples it makes it so easy to grasp to concepts. he will explain the code then sometimes he will tell you why it was added.
Awesome Mr. Ryan, everyday I learn more of your videos, thanks for the time and dedication that you take making this videos us in the Electrician trade. Good Bless You.
Hi mr Ryan as always something useful for the trade thanks for keeping us up to date with the code i do help a few contractors and if something really annoys me is when they have me use single devise boxes on my personal jobs i always use 4/S deep boxes and if i know costumer plans to use dimers i like to set the box a little deep and use a deeper plaster ring just to be safe and have plenty of room even if the difference has to come out of my pocket as i ask them to pay for material and my labor that's how i do my jobs so if i have a disagreement i will only lost my working hours but no material
When I started out back in the 1960's a lot of guys used roofing nails to secure metal boxes. At a large slaughter house that I worked at they nailed in couple hundred of think they were only 1.25" deep octagon boxes for porcelain lamp holders. They used long roofing nails on the beams that supported the metal tracks in meat cooler that meat trolleys rolled down. The vibration over several years caused some of the roofing nails to come loose causing a short when it came into contact with screw that black wire attached to. Took us several days to move heavy hanging sides of beef and pull out all the roofing nails and install hex headed screws to secure boxes. Luckily have not seen anybody use roofing nails in last 45 years. Never a fan of how some guys only use a chase nipple to secure a 1900 box to side or bottom of a panel. Thanks for another great vid.
Hey Ryan, new subscriber. Wyoming licensed electrical contractor. Been on an extended "sabatical." I'm a bit rusty to say the least. Watched your video on xfmrs-very good. Looking forward to seeing more of your content. Thank you so much.
Most of the electric work I have done was on an old lath and plaster building. A trick I learned from an electrician was to use new work plastic boxes and attach them to the studs with screws through the sides of the box. Using old work boxes on lath and plaster walls is problematic because it is difficult to position the box so as to make sure the clamps are positioned to clamp on a solid piece of lath. Even if you succeed in positioning the box optimally with respect to the laths, as the box is used it can work loose. IMO, using the screws was the perfect solution, but I was always concerned that it might not be code compliant. Based on this video it sounds like it was. Although if I had seen this video I would probably have put the screws a little closer to the top and bottom of the box than I did. Thanks for the video.
Ryan, curious about your thoughts on enforcing 314.23 H 2. I was shown a method for hanging exit signs with emt, where we would drill through the connector and the emt and use a bolt of some sort to throughbolt the emt to the connector. Would you let this slide if you saw it out in the field? Im not sure if I would do it personally.
Hi Ryan thank you for the wonderful videos always I have a question about section e the exception that attaches I know this has usually been applied to 2 lb's but I'm still not understanding why does not apply to boxes and I'm also not understanding what is talking about when it deals with only one conduit this appears to go directly against the code above what are you need to entry conduit and say if you have a box that is rated for three-quarter inch pipe and you only have one pipe going into it can be supported from only one pipe can you help me
(4:05) as soon as you mentioned "through the box," and including screws, my mind went straight to wondering about how to protect the conductors' insulation from the slicing of the screw threads
Thanks for the informative video. I was left with a question regarding pendant light fixtures hanging from swivel plates - you cover these at 15:36. I'm clear that RMC / IMC must be used, but what about when the light fixture in question wants to be mounted to an electrical box - for instance an exit sign that doesn't have a threaded hub in it? Like Lithonia LQM. Could one use a 4x4 box with a Myers hub in the back?
Thanks. I'm not an electrician but am frequently called upon to look over work before the inspection so try to understand the "bible." This is helpful information.
I understand that the box can be supported by the raceway, but the example in 10:27, the raceway coming out of the box to the top of the screen seems to have a conduit support fastened to another raceway. I can tell it’s a raceway because there’s a strut strap securing it to the the strut. I can’t tell if the support is secured with a back to back mini set up or zip screwed to the conduit. Is this still legal?
You show a picture 10:23 in video with compression emt entering threaded box and leaving , my question is emt allowed or is it supposed to be threaded pipe like ridged or imc.
Great video Ryan. But on the example on 10:27 that is a EMT raceway with EMT connectors on the threaded entry of the box it is not a threaded raceway, if I was RMC or IMC it would definitely comply but on this example it just causes more confusion.
Great video as always. On the topic of 314.23 (E) it appears to have emt with compression fittings. Is that acceptable or does it need to bed RMC or IMC?
Mr ryan , is there anything on the nec code book that says we have to use galvanized screws to mount electrical boxes onto wood stud?? Just got a red tag because I used drywall screws instead of galvanized screws
You can read it that way, but it definitely is not the intent. I've brought this issue up as well, and it is a valid issue, but reading the statements from the Code-Making Panel make it clear that the intent is for the AHJ to evaluate on a case-by-case basis.
I would fail any screws going through the side of a box that are not part of a non metallic box. I get you saying it is not a 3-way switch but someone could trim it out with a dimmer and many these days have the option of being a 3-way or single pole. If they used pan head screws and used a bond jumper I might be okay with that? Best bet if if you have a tight space there are other type boxes you can buy to avoid the entire issue. Old school me would just use my linesmans and a hammer, would just take a few seconds.
On the box hanging from a cord, a 1900 box may pass NEC (?) It will not pass an OSHA inspection and is a violation. The enclosure must be used for its intended use. A 1900 box is not intended to be used in such a fashion, the yellow box in the photo is. A client had many 1900 boxes on cords with nice grips but OSHA wrote them up and we had to replace them all. Yes, they were fined and reinspected after installation. Talking to the inspector they said more or less the unused knockouts can bend inward can short or contact the hot wire. I don't recall the actual code anymore... Lesson learned, use the properly rated enclosures
That's not entirely correct. I spoke with OSHA on this exact issue. They said it doesn't comply with 314.23(H)(1), and they are completely wrong. The word in that section is APPROVED, not LISTED.
At 10:46 those conduits look like emt. I do not believe that's code compliant even with the support within 3ft on opposite sides. Also, there is a question on whether the conduit has to be threaded itself to be wrench tightened into the box with hubs or threads. So basically emt cannot be used to support a j box, but can be used to support a conduit body
@@RyanJacksonElectrical I’ve come across videos that say it is illegal to put standard interior Romax, inside of a conduit apparently metal or pvc just wonder why. Thank you

Thank you!!
Great video. I appreciate how you use real pictures and match them to the code references.
Great video! In your example at 4:30, another option for the installer would've been to use a 6" bar clamp to squeeze the nails into the stud.

I would enjoy a video on your literature collection back there! Maybe spotlight a few good reads and/or useful information sources.
Interesting. I might do that.

You are the best 👍
Very educational...🙏✅️✅️⚡⚡
Agreed with the increase on Suze
Of single boxes devices...too small
My dad used to do that mounted a box to a tree for lighting up the yard.
Keep the videos coming.. 👍
Here in Houston it’s impossible to get QO dual function breakers
excellent. Thank you.
Are you talking about plastic cut in boxes or metal boxes cannot be install in fire rated walls as well?
A like is the least I can do for the intel thanks brother

I’m curious about his too ,I thought it had to be threaded pipe ?
@@jlmm3968 my thoughts exactly, I’m very confused lol
what about requirements of supporting junction boxes in the attic?
Great video as always. On the topic of 314.23 (E) it appears to have emt with compression fittings. Is that acceptable or does it need to bed RMC or IMC?
From my understanding it appears as long as the box is threaded it does not matter what type of conduit is used
Good catch. The raceway must be IMC or rigid.
@ 10:30 one of the raceways out of the box looks like it is supported by another raceway, is that an approved support?
5:40 What if they mount the switch upside down?
Thank you
This is a good example where an electric/pneumatic hammer cold be used to drive the nails into the stud
Video on code requirements for wiring docks.
Mr ryan , is there anything on the nec code book that says we have to use galvanized screws to mount electrical boxes onto wood stud?? Just got a red tag because I used drywall screws instead of galvanized screws
No.
@@RyanJacksonElectrical thank you mr.Ryan, it must be personal preference for the inspector or city then
Support holes made in the field must be approved. I read that as they cannot be turned down. They "must be approved".

@@RyanJacksonElectrical are you going to edit your video to show that photo was not code compliant?
I'll put it on my to-do list. I can't do it right now.
Sure driving the cost up
I know it’s not relevant to this but why can’t you use run standard Roman in a EMT for protection?
I'm not sure what you are asking.
@@RyanJacksonElectrical I’ve come across videos that say it is illegal to put standard interior Romax, inside of a conduit apparently metal or pvc just wonder why. Thank you
@morgan79347 NM cable in a raceway is fine, unless the raceway is in a wet location. See 358.22, 300.9, and 300.5(B).
Only a woodpecker can mount a tree. Lol
I approve those holes in that box ...
