Introduction to UL 508A Industrial Electrical Control Panels with PLC

[@LuisHernandez-pr9xv]

Hi Tim! I would like to thank you for the excellent work you have done. About a month ago, I started studying for the UL MTR exam and came across your video. While I was studying for the test, I used your videos at the same time. I can tell you it was very helpful. I have been designing control panels for a while, and our company decided to build our panel. I don't know why this test and certification don't get more recognition. The test was difficult, even with my background in electrical engineering. So again, thank you. You have a new fan here. And yes, I passed the test. Lol

[@TimWilborne]

That is great to hear! Congratulations!

I like that your disconnect handle will literally cover an inch of your HMI when you turn it on with the door closed.

[@TimWilborne]

That's all you got out of the video....😂

Many thanks from the UK.

You are welcome!

[@taylor2160]

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.

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.

[@TimWilborne]

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

[@christopherlyons7613]

@@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.

[@TimWilborne]

@@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.

[@isaacparry8686]

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!

[@bblee2150]

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!

[@TimWilborne]

I am going to soon but you won't like it. The only color that is required is green for grounded conductors :)

[@aboshnb97]

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!!!

[@TimWilborne]

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.

[@rixpanapasa8977]

Awesome vid Tim....Thanks

[@joshkraai7657]

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)

[@TimWilborne]

We're working on a panel layout video. It is a little tricky but hopefully we'll get the kinks worked out.

[@christopherlyons7613]

​@@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.

[@irwinjimenez]

I see that you are using the NOARK MCP's and contactors. Can you make a video with brands that you can recommend? I get told often that Automation Direct parts are low-grade, Phoenix Contacts are mid-grade, and Allen Bradley is top-grade. The pricing would reflect that. I personally like using any of these brand. What is your take?

[@TimWilborne]

I don't get into these brand debates. Here is my only take. kzbin.info/www/bejne/oIGUlJ9ojrefiKc

[@steveestey]

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?

[@TimWilborne]

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.

[@Bosanac_99]

Would products certified only to the UL508a standard be accepted in Canada?

[@TimWilborne]

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.

[@Bosanac_99]

@@TimWilborne OK, one more question, please. Would cUL508 certified products be accepted by CSA standards in Canada?

[@csdrip]

Is there a list of labels that are required by UL for ICP's? For instance "to maintain overcurrent protection...."

[@TimWilborne]

Not in a broad sense. There are some labels every panel may require but many are specific for the situation.

[@dwaynes5983]

I always leave the space above disconnect open. Thought it was code back in 90s??

[@EETechs]

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.

[@TimWilborne]

UL says "power wiring" must be 14awg, with a few exceptions, they don't specify control wire size.

[@coasterbp]

Hey Tim, Do you through bolt your components to your back plane or drill and tap?

[@TimWilborne]

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.

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.
