Thanks from New Orleans!!
You are welcome
This is what Ive been waiting for. Looking forward to this series.
Glad to hear it Adam
Many thanks from the UK.
You are welcome!
you probably have the best presentation so far. good stuff. will be watching the entire series.
Glad to hear that, thanks!
great way of teatching
thank you from Morocco.
You are welcome!
Thank you so much Tim! I just love watching yours video!
Glad to hear it!
Nice job with the ferrules.
Thanks!
I work for Prime Controls in Dallas and really enjoy your videos!
Glad you like them Jeremy!
I would like to question the spacing requirements for your components. UL got me with that on my first panel that got inspected. Typically a power supply, especially ones that convert 3 phase into 24vdc require at least about 1.5 inches above and below. It does not look like those requirements have been met. Love your videos man. Great content. Would love to ve able to bounce automation ideas back and forth.
love it! do more of these!!
We plan on it Jason!
Much appreciated Tim
You are welcome
wonderful, I liked your all playlist and save in library and subscribed before your promotional words :)
Awesome, thank you!
I like that your disconnect handle will literally cover an inch of your HMI when you turn it on with the door closed.
That's all you got out of the video....😂
Awesome vid Tim....Thanks
Put in your request for what you want to see in this series.
@@TimWilborne would really like to see how you size up and set up the electrical panel .
Good video'
I want to learn this tips.
Great, we'll be uploading more videos about this soon so subscribe.
I always leave the space above disconnect open. Thought it was code back in 90s??
I watched the "hater" episode. I like how you were accused of selling yourself for AB when in reality most things you have in your videos is AD stuff. That's a testament to an untrained eye. Minus maybe the PLC! I'm pretty sure I even saw a DL05 in there somewhere. Personally I'd rather use the DoMore! in one of it's various form factors, or I hate to say it, a Micro800 of some sort for simple applications. (although you absolutely should hard code you're variables in those as they have a tendency to go brain dead for no reason!) The Click! isn't much more reliable, but it is cheaper. Both software's are free. (At least the non-developer edition for the AB) Anyway, I like you're series, you are a pioneer in the socialization of the field. WE NEED MORE CONTROLS GUYS, people don't understand how fun this stuff is! I almost want to keep it a secret, or everybody will want to do it!
Hi Tim,
Thanks a lot for all the tutorial videos. I learned a lot by following your tutorials really appreciate that. Is there any video about calculating the total load of the whole control panel by going to each components? I'm trying to get that for my application in order to size a step down transformer and a safety disconnect switch. Thanks a lot!!!
This is one I have avoid because it's not as simple as adding up all the loads and multiplying that by safety factor, it depends on the types of loads, size, and locality.
Nice video Tim! Can you talk about the wire color coding when building a panel? I can't find much information for the color coding for such as AC voltage, DC voltage and etc.
Thank you!
I am going to soon but you won't like it. The only color that is required is green for grounded conductors :)
Can you use MTW 16 or 18 AWG wire inside control panels for the control wiring to save on money for wire as long as the proper fuse size is chosen? I read somewhere that UL508a says only 20 AWG or smaller wire has special requirements limited to PLC connections only.
UL says "power wiring" must be 14awg, with a few exceptions, they don't specify control wire size.
I don't see a grounding lug for the incoming power.
It's the green thing 🙄 Did you have a question about it?
Just wanted to let you know that I found your youtube channel from Linkedin and Jake Hall!
Love Jake Hall's videos!
I really enjoy this video break down in easy terms to understand. I would like to see in one of your videos how and why you choose the panel lay out you did. Like which components can be next to one another and how you have to be careful about wiring crossing each other (high voltage/low voltage)
We're working on a panel layout video. It is a little tricky but hopefully we'll get the kinks worked out.
@@TimWilborneHI Tim. Have you made any progress on doing the Panel Layout video? That would be great information to show and it could help many of us. Thanks.
Is there a list of labels that are required by UL for ICP's? For instance "to maintain overcurrent protection...."
Not in a broad sense. There are some labels every panel may require but many are specific for the situation.
Hey Tim! Have you done any videos yet going over how to calculate SCCR?
It is up for the next group of control panel videos.
Hello, I don’t find wiring diagram on video description
You're right, we're revising our website and that link is missing. See if I can get it put back up.
I have main ac panel ,ac distribution junction box.in ac panel we have main mccb(earth protection) for on-off,
Ac distribution Power cable taken from Ac panel main circuit breaker control.
Is this needed any separate mccb for ac distributions box .(in ac distribution box we have 30 MCB,30ssr,two controller).
Yes there is more needed, you need to dig into the NEC book.
@@TimWilborne Thanks for your response.Could you please share authentic links for NEC ,UL508A.
Suggest any course are there for ul508a .
Hi Tim. Thanks for your videos. I have a question about UL508 wire colors. Can you please provide some basic info on recommended AC & DC wire color guidelines.
Also, what format do you use for your wire numbers? Thanks.
I have a video on wire colors in my drafts. Many people don't like my answer but according to UL 508A for industrial control panels which is what 99% of labels are, you only need to mark grounds as green. The rest is regional and even varies across the USA. I'll have some examples in it.
Here are some sample wiring diagrams, the wire numbers are based on the page and line number.
controls.tw/sample-drawings
@@TimWilborne Thanks. Doesn't UL508A make some statements about wire colors (i.e.66.5 (Power) & 66.9.1 (Control Circuits) (not sure if these are current section #s)? I believe they state that all ungrounded AC power connections should be BLACK (RED if < supply voltage) and all grounded AC connections should be GREY or WHITE. For DC control circuits they say to use BLUE for all ungrounded DC connections and WHITE WITH BLUE STRIPE for grounded DC connections. I realize there is some openness in the spec regarding these colors. But if you were to follow this basic color scheme would that be sufficient? Are there any other basic colors that you tend to use? Regarding your upcoming Wire Color video, any idea when it will be released? Looking for a beta tester? Appreciate any help you can provide. Thanks.
@@christopherlyons7613 No, this is the most commonly misused sections. 65, 66, and 67 are for Industrial Machinery, not industrial control panels. Industrial Machinery labels are very rarely used, in fact I've never seen one.
Hi, I dont see schematics in description to download. Is it removed?
No, we're moving some links around right now trying to consolidate items, here you go.

Hi Tim, great series! I noticed one thing in particular that surprised me, you don't label your panel components, why is that? Also I live in Canada and this may just be a difference in code requirements but I also noticed no fuse charts on the door, are you guys not required?
Our UL standards are the same. As far as labeling, it can be done by the component, on the door in a panel layout such as you mention, or on a drawing. This is one of our training panels so it get reconfigured often, hence not permanent labels.
Hey Tim, Do you through bolt your components to your back plane or drill and tap?
I'm 99% sure code doesn't allow through bolting components. And if code doesn't prohibit it then it should. I always drill and tap. If the diameter is too large for the thickness of the panel then they make volts that can be riveted into the panel.
How do you make the label for the outside of the panel is this special software ?
Hi Kevin. I use a Brady BMP71 for all my labeling. See links below.
BMP71 amzn.to/3cqs3FN
Nameplate labels amzn.to/3oAsDD9
@@TimWilborne thank you
What kind of license/permit/certification do I need to do this kind of job and being certified by UL?
For UL, it is UL508A
Would products certified only to the UL508a standard be accepted in Canada?
There is a Canadian marking for UL 508A. It has a C on the left side of the UL and a US on the right side.
@@TimWilborne OK, one more question, please. Would cUL508 certified products be accepted by CSA standards in Canada?
Hi Tim,great videos..i really like that disconnect switch what brand and or PN is it?
It is a Noark.
Thank you!
please am from Ghana
how can I buy a micrologic 1100 or 1000. I have been searching since in my area but can't find one
The first question is what PLC is popular in your area.
@@TimWilborne so far in all the company's I worked as an intern they don't use one brand, I have seen Mitsubishi, Siemens, Omron and in my school they use Allen Bradley
Do you still have classes? Where are you located?
Yes in Roanoke Virginia. You can learn more about our training at:

Where can I get that enclosure?

Good afternoon, I’m about to start classes to be a ul 508a Mtr. Do have any advice and recommendations of books I should have? Thanknyou
Do UL's practice exams. They cover everything you need to pass.
@@TimWilborne thank you
Good luck. Definitely don't go into the test blind. It was difficult
Good afternoon, do you know how I can find the practice exam? I’ve looked on ul website and couldn’t find anything on an practice exam for ul508a
I don't see the wiring diagram, I'm still a nube and I like following those for practice. I love this channel though!

@@TimWilborne Hey, you actually answered! Well I enjoy your videos so I signed up for the first tier of Patreon. Keep up the good work! Thanks for the link too.
@@danielsowa8209 Thank you for your support!
what is standard of wire color sir?
According to UK standards, ground has to be green. The rest is regional. I have a video coming on this.
@@TimWilborne I hope to see it soon
sir pls make videos over VFDs
See link below.

Iwant take online course so how to take?
Here you go.

Where's your overcurrent protection (fuses)????
Uh did you watch the video? There in it...
I'll answer myself = 15A main CB so motors are group protected. The LVPS must be a self protected type?
@@TimWilborne I don't see any fuses, nothing rated 5kA but I may be blind. Is there a link to the electrical schematic? Might be a good idea?
UL508A requires that the main switch (CB) be able to be switched with door open, I don’t see a handle that allows that? Anyway I subscribed and will check out some other video's. Great response time ... lol
What!? I like the beard.
"Does it need a label?"
Can you just say yes next time?
That would be the best answer 😀
Is grounding important? 🤣😂
Can you tell I used to work at a place where they didn't think grounding was important 😁
Hi Tim, I have a computer science degree and a minor in electronics, I became an electrical contractor while studying. I did an online PLC basics certification. I am thinking of doing the PLC II which covers Rockwell 5000 series, SCADA, DCS etc. My question you you is what else do I need to get enough knowledge and experience to start offering my services for the automation industry specifically, PLCs, scada, MES, and ERP integration?
The biggest thing would be opportunities for troubleshooting experience. That will go further than PLC II.
