Awesome! thanks for what you do. In my line of work being an electronics maintenance technician i wish we had more people in the industry that use the guidelines and presicion that you yourself use. It is very satisfying to watch your videos, whether you are wanting to get into that field of expertise or you are like me and always want to continue to excel and learn more information. I appreciate you being very thorough and making it simple for most people to understand.
I am an older PLC engineer from the UK now living in Canada. After being out of the game for quite a few years, I decided I wanted to get back into it when I was contacted out of the blue by a recruiter & wanted to brush up my practical skills a bit, no interview yet but it is coming I am assured. I love the videos, practical & very good, I have forgotten a few bits & bobs in 10 years completely out of it as well as learned a few new tips. I lost interest back then because I had been made up to management, ending up as production manager but I prefer getting my hands dirty. Back then I had to critique my production guys' panels as their mentor/supervisor. What got to me in the end was having to lay several off in 2008, after which I resigned because I felt so bad about doing it. One point about shielded cables: You strip them back & remove the foil...OK as long as you can do this...check the drawings, notes or with the designer first! The biggest area where these signal cables will be exposed to electrical noise is inside the cabinet & especially when bundled alongside (not so much at right angle passing) inside wire ducts with other cables. Duct groupings & pack density are important...don't put high energy cables in with small signal or data cables wherever possible. Your point about slipping a bit of heat shrink over the bundle of MC cable is a good one (video 5.08). If you look at the cable, it is made of individual twisted pairs...this is to cancel out induced noise & cross talk so you want to preserve the twist as best as possible.... ALSO... Shielding for cables where it is preserved must only be connected to Ground at one end (source end normally) to prevent stray or induced current flow in that shield.
@@TimWilborne Thanks for the response! I work one 48 shift a week so I have 5 other days to do something. I was thinking of doing something like this. I think automation/control panel building is awesome. I just don't know where to start. Where can I go for training After I learn how to build the panels, whom do you sell to? Who is in the market of control panels?
Hey these are some great videos. We had a company come in for certification and they were strict on removing paint under din rail where it screws in for more of a bonding connection. Also I've tried the drill/tap combo bit and found that they broke rather easily, do you use tap oil when using these bits or have any suggestions on using them? Maybe I just had a cheap brand? They sure would save a lot of time.
Hey Tim! I have been binge watching your videos and always look at your videos for support when needed. I can’t seem to find the article section on your website. Has this been removed? I see a bunch of articles that look very interesting. Love the videos!
These videos are awesome!!!! I still need to send you that email. I really appreciate how you keep everything like an operating room. Your work is only as good as the work station and the manner it’s kept in. I wish more people took pride in their work as you do things would be a lot less complicated. I need to get with a pro like you and just learn.
Thanks. I think our next series will go through the basics of getting started PLC programming. We've covered it before but it could use freshened up. Thoughts?
Just stumbled upon your videos. I had a question about the color code. What is the preferred color code for wiring. Im currently working on a project now and I just want it to look as best as possible for whoever works on it after I'm gone. Awesome Videos!
Thank you! Do you do your own drawings for panels? If so, what program do you use? Is that the one you recommend. Also, what kind of printer do you use for your heat shrink labels?
My CAD software is out of date but I am seriously exploring ePlan. Check out this video we did with Phoenix Contact on printers. ua-cam.com/video/jk9ECl5yd0k/v-deo.html
I don't recall on this particular panel. It was controlling two motors that needed variable speed. Once controlled by a START/STOP and the other was a momentary FORWARD/REVERSE.
Hi Tim, thanks for the great tutorials! Quick question - according to the governing bodies (UL, etc.) - when feeding a branch circuit's breaker from a main breaker, do all the wires between the two need to be rated at the rating of the main breaker? I.e. 100 A main breaker feeds ten 10 A branch circuits' breakers - do all the wires on the supply side of the 10 A breakers need to be rated at 100 A? Seems overkill, but really nothing protecting the branch circuit feeder wires from shorting to one another and exceeding their capacity (up to 100 A), in the alternative case (using wires sized for 10 A). Or is that edge case assumed to be unlikely enough to not address it? Thoughts? Thanks in advance!
Hi Tim, iv been going through and watching a lot of your videos, all explained very well! Just curious here, i see that the panel is powered by 3 phase. Did you just pull from 1 of the phase lines and a neutral to get a single phase line for the 24vdc power supply? If so, is there any disadvantage of having one of the phase lines drawing more current than the other two? Thanks
Hi Jordan. That power supply is a 240VAC single phase so it was capable of being powered off of two legs of household 120VAC. The drives are capable of being powered for a short time off of single phase 240 single phase as well but will eventually fault. Overall you want to keep your loads as balanced as possible across the three phases as possible. Also I do have a rotary phase converter that creates 3 phase power for testing, here is a video on it. ua-cam.com/video/k9tR9d3DsqY/v-deo.html
Thanks for watching! While we aren't planning on a how to make a schematic video, we are planning on going through reading some various sample schematics and talk about the pros and cons of each one.
@@TimWilbornethank you for the quick response. All the same it should be equally helpful, I am building a control panel for a senior project for engineering school; they don't show any of inner working or how to go about designing one so your companies videos are extremely helpful. The sample schematics helped a lot.
Hi, Tim, I have a question. Do you use #4 wire to connect the first 3P breaker from disconnect , then use a smaller size to hook up from the first to the rest breakers? Thank you very much. I am a fan of ya.
Are you talking in general or on this specific panel? In general you may start off with #4 going to a 60 amp load, but if you are going off of it to a small transformer then I would drop to #14. Thanks for being a fan!
@@TimWilborne Thank you so much. I mean on this specific panel. It looks like a #4 wire connecting the first 3P breaker from disconnect , then wires in a smaller size jump up the breakers from up sides. This was my understanding and observation for the above video.
Yes, electrical equipment must be approved by a Nationally Recognized Testing Laboratory (NRTL) in accordance with the OSHA requirement at 29 CFR 1910.303(a).
Hi David. It is much easier than you think. The series at the following link covers most of what you must do to build a UL panel. Once you're comfortable, pick up the phone and call UL. They we're very helpful when we were getting started. twcontrols.com/ul508a-control-panel-building

Why didn't you heat the shrink tubing? Great videos btw!
I did, just hadn't done it by the end of the video. One of the last things I do.

Thanks for another great video! Do you have to ground every din rail when wiring a ul 508a panel?
As long as the panel is steel, you only need one ground connecting to it. DIN rail is grounded through the screws that hold it down.
@@TimWilborne thank you! You’ve been a big help throughout the years!

Thank you very much, but I'm wondering, this panel is for what exactly, for which kind of control ?
I don't recall on this particular panel. It was controlling two motors that needed variable speed. Once controlled by a START/STOP and the other was a momentary FORWARD/REVERSE.

What model wire stripper and crimper do you use. Appreciate if you can post the link
Wire Strippers amzn.to/2T4fw34
Wire Crimpers amzn.to/3vXHPij
What is that crimper that you used in this video. I think it would be a great tool in my box. Thanks

@@dennisjiu1771 Yes your observations are correct.
Hi there just found your video series. What type of printer do you use for your wire labels? Great Video
Hi Cory. I use a Brady BMP71. See link below. controls.tw/trndr
What is the process to sell these? Is there certifications? Would like to do something like this on the side after school
Yes, electrical equipment must be approved by a Nationally Recognized Testing Laboratory (NRTL) in accordance with the OSHA requirement at 29 CFR 1910.303(a).
What are the radial strippers you used for the larger power wire?
Hi Alexander. I haven't been happy with mine overall. I think next time I would try these, amzn.to/2JCaAOu
@@TimWilborne thanks!
What size control wire do you normally use?
That is very dependent on the system design.
How do I become UL 508A panel building certified or is it even cost efficient for small companies.
Hi David. It is much easier than you think. The series at the following link covers most of what you must do to build a UL panel. Once you're comfortable, pick up the phone and call UL. They we're very helpful when we were getting started.

Sir if have problem in electrical control panel nd I don't know where is connected one side is control cable then how I find nd check that cable
Finding the wiring diagrams would be the best place to start. We have a troubleshooting series coming out that will help you from thre.
I just checked my hands xD
