Electrical Wiring- 3 phase panel detail

www.electricalindustrynetwork.com In this video I am describing how a 3 phase panel is built and how the bussing works in accordance w/3 phase power. It is part of electrical wiring systems common in the U.S.. This electrical panel is a 3 phase 4 wire 120/208 v 200 amp panel with 42 spaces. It is considered a bolt on breaker style with a main circuit breaker.

Considering this was uploaded many many many years ago means video quality is always going to be an issue. Regardless, love this video. As a licensed electrical engineer, most of my work evolves around drawings and getting to see how the actually detailed mechanism and wiring works great. This also allows me to understand how the breaker is actually mounted. Thank you!

[@electricalindustry]

Thank you! Over the years I have had many EE's ask me to see pic's of the real thing for the same reason. Let me know if there is something in particular you would like to see and perhaps I could do a video about it!

[@AndrewMcJannettSmith]

Great explanation on how a 3 phase panel works.. one of the only video's i have found that is simple, short and that you feel like you have come away educated.

[@electricalindustry]

Awesome! Thanks so much for your comment!

[@markrarey3834]

I have a commercial building and it has 3 phase. We had one of the phases go out. I had to learn that its possible for that to happen. 1/3 of our power was on in the building. A real learning experience. Thanks for the video!

[@electricalindustry]

Thank you!

[@Neondream531]

Thank you! Sign guy here buried in learning the NEC code book, and this video helped me with visualizing this!

[@chasecrump9276]

great explanation! I've been so confused in the 3 phase panels in school. I mainly do residential electric work so i never get to see these panels. This cleared it right up for me!

[@electricalindustry]

Thank you,I'm glad it helped!

[@Amanda_Axolotl]

I really find your videos useful. I like Fritz have a degree that has gone unused because I went in a different direction but find myself returning to old skill sets to make a living. You videos are a wonderful refresher to those of us that are a little behind in the actual application of the trade and as you said to some goof down ing the postings, we all have to start somewhere. Thanks and keep up the great work.

[@texasjourneyman207]

I'm a journey man in Texas and I will be the first to tell u that that's a beautiful looking panel and people don't understand that's it's not easy to make them look that good it takes finesse lol but u did a great job

[@muchacamara]

It takes BIG balls to do that.

[@georgeswindolljr1980]

Is that strande wire or solid????

[@ryanthepianoman27]

@@georgeswindolljr1980 hype!!

[@electricalindustry]

That really is a good question! For years I thought that I didn't need to know about Ohm's Law.But as I moved into a different direction in my career I realized how important it is to understand it. I started doing a lot of remodels and service calls about 15 years ago and found out quick that I need to know more. I think if a person really wants to succeed in the Electrical Ind. they must understand all aspects of this industry.My advise--Learn as much as you can about all aspects of electrical

[@robertgreenwood5160]

Nice presentation explaining the panel! Appreciate your time and trouble, and answered most of my questions too.

[@danmcclaren5436]

New mechanical engineer at Schneider Electric here. You helped out a lot sir. Thanks.

[@electricalindustry]

Good luck in your career and thank you for the kind comment!!

[@wm79198]

Congrats on the job, designed in America! Tell your boss they need to up their game on the QO/HLINE breaker terminals. Those basically flat plates that can take two wires are a real weak spot, and pain to tighten down square. Whoever wired that panel in this video knows what I'm talking about. www.google.com/search?client=ms-android-verizon&tbm=isch&q=square+d+qo+breaker+wire+terminal&spell=1&sa=X&ved=0ahUKEwi_lOz6ydjZAhUo5IMKHZ_IBtEQBQhLKAA&biw=360&bih=612&dpr=2#imgrc=JOBubWs_jkqu-M:

Absolutely the Best 3 phase video, great !

[@driver9313]

Excellent video that simplifies 3 phase into laymen's understanding!

[@mossielgomez2646]

Great video, very thankfull for people like you that takes time to teach alot of people like me in 6 minutes, is awesome thanks alot sir !!!

[@Ishootback239]

Awesome video, you literally broke it down so simple and easy to understand.

[@ritawix8217]

Thank u for the video. It is the most succinct explanation of a 3PH panel I have seen. Being a female apprentice I am hesitant to ask for more explanation if I dont initially understand something bc the belittling I get from the instructors is just not worth it. I have learned more from KZbin than I have in 3 years of classroom theory. I really appreciate ur knowledge & the fact that u share it so freely. Be safe & thanks again!

[@electricalindustry]

You are so welcome. It really helps me to know that people can learn from videos like these. All too often I forget to mention something or misspeak in a video and I become a hack or whatever else the youtube trolls feeling like calling me that day. NOBODY needs or should be belittled. Let me know if there is anything else I can help you with!!

[@ritawix8217]

Thank u - appreciate the response. What I can say is that what helped the most is that u broke down the panel into its most basic components thereby making the info that follows much easier to absorb. All to often senior mechanics tell u WHAT to do, but rarely tell u WHY ur doing it (I realize that time constraints do not permit explanation of every little thing but really, panel installation instruction HAS to be concise . . . its basically the heart of ur electrical system) Even when a mechanic is actively trying to impart knowledge they inevitably omit something because it is so rote, or ingrained in them and their personal experience is so far beyond that initial step, they automatically gloss over it. I love the detail in ur videos. And when u think about it, WHO are u trying to reach . . . the people who want/need to learn the trade or the trolls who think they already know everything? As for "anything else" . . . If u have a video on Fluke testers please let me know. As much as I hate to admit it this far in, I have basically no experience with it (we are treated as assembly-line monkeys) so we just do commercial installations before anything is energized.

[@electricalindustry]

Thanks, I know over the years I've heard "your not ready for it" or "I don't have time to explain, we need to get this done" Another thing is they don't know how to explain it they just know how to do it. I haven't made any videos specific to a Fluke,you didn't say what type but maybe it's time I make one. I have a couple different Flukes designed for different purposes. Thanks again for commenting and watching my videos.

[@kr5746]

as a female apprentice, it is your job to learn as it theirs to teach you. electricians and shops will come and go, but the knowledge needs to stick. the best revenge is success.

[@lgrantcdg]

Excellent introduction for those of us who have worked only with single phase. Thank you.

Halo bro

[@luisamoroso3648]

Brother thanks a lot for the video. I never comment on you tube but I had to on this one. I'm an apprentice and just joined the union and this really helped me have a better field understanding of phasing. Thanks again bro.

[@robertmcknight1352]

I'm studying three phase from an electrical engineering book for my Master's License. (plus a challenge from my company) Although we use it and know how to use it, the principles behind it is intriguing. Keep up the good work.

[@electricalindustry]

Thank you and good luck in your studies!

Great Video! Thanks For putting it together!!

[@electricalindustry]

@davec3487 Most of the installations I run across the motor starters are located near the motor. All of the car wash's I work on have a MCC,Motor Control Center, located some where in the equipment rooms. So really it depends on the application.

[@Movielunatic]

We are a third of our lives at work! How little we store memories from this period? In fact, I have tried to record some of the events on film and video! Use every opportunity and record the people on the job, working methods, in order to leave some memories to future generations. The time it takes an amazingly fast!

[@fedotbarsukoff9599]

Thank you for keeping it simple understand perfectly

[@epetelawrence]

Great video great explanation

[@electricalindustry]

Absolutely.You would need 1-single or double pole breaker installed. Wiring to your device would be hot,neutral and ground for a single pole and depending on your requirements you could run two hots to a motor,light or whatever. Always check your spec's before running any power.

[@electricalindustry]

Much thanks for your comment.

[@jeepernj99]

hey this is a really good video. You explain it very well. Nice job.

[@stanislavf]

I find these useful and my degree is in EE. They are a good, quick sanity check after not using my degrees in decades and of course for EE I was concentrating on integrated circuits and signals and systems, not power engineering. Keep up the good work and ignore the criticisms that are out of wack.

[@jaybrown7088]

Thanks for sharing, great learning experience.

[@electricalindustry]

There are many varieties of breakers and panels. 3 phase panels are built both plug on and bolt on styles. There are 3 phase load centers(plug on) and 3 pahsepanelboards(bolt On).You need to use the specified style breaker to match the type of panel your using.

[@frankiek.3742]

It would have been really cool if you had also detailed the wiring on this breaker by doing mock install of the wires into the terminals as you explained the panel. All n' all, great video.

Really like these videos, there isnt a whole lot out there that explains in detail on three phase panels / wiring.... Do you run into a lot of three phase with a high leg, or are most 3 phase 208 / 480 systems?

[@sheseems]

Awesome video, keep them coming. Can you explain a splitter panel setup? I just went through intermediate for my apprenticeship. We did a lot of splitter calculations but nothing practical.

[@andrewperez5290]

Great video man

[@isaacvmadrigal1047]

great explanation

[@NWPRcharlie]

Great explanation of the subject, but I do have a question specifically about the MCB panel. I have a Siemens panel that looks identical to the MCB panel in your video, maybe a little smaller. However it didn't come with the white switch at the bottom, nor is there room or a location to mount one. How do I go about getting my power into the panel? Any help is appreciated thanks.

[@jmb1rox]

Finally a decent looking panel button-up on youtube! :)

[@marqaudio]

Very helpful - thanks!

[@noshmasters]

great video.

[@peterwillymcjohnsonator7837]

my father had installed a GFCI outlet in the kitchen. He wired it up, turned the power on, and plugged in the coffee maker, the bottom outlet worked fine, the top when plugged in tripped the GFCI breaker. So he broke out the manual, and found the wiring was backwards. turned power off, removed outlet, and wired it the right way. Works great now. Still goes to show. Even AC power doesnt have poles, (like DC) correct wiring is a MUST to prevent faults. I believe hot and ground was switched?

[@layintrax]

Great info, thanks!

[@MrWhalen80]

Great video, glad I found it and i understand the explaantion too. It would be better if u had more lighting on the pics, but they were not bad either.

[@tedlahm5740]

Wonderful explanation. Only small change, On a single phase step down transformer ( Panel not shown) used for most households, only one phase. "which is split phase" Thank you, of great information, although most of us will never deal with this much power, which is 1.5 times more power than single phase.

[@electricalindustry]

What are the breaker configurations 1p vs 2p?Have you taken amp draws on all breakers or just the main? Balancing is done by relocating breakers to another phase depending on 1p vs 2p breakers. Balancing a single phase panel vs 3phase panel are 2 different animals. How did this panel get to having a load difference? 200+ on line 1? What size is that panel? THere is a little more to it but these are the basics.

[@gladiator2.039]

Good and helpful video

[@anomalyjustin]

Also, I'm asking mostly from a theoretical standpoint, not necessarily whether unbalancing the phases will cause specific problems like burning your house down (I know it won't). And I know that the overwhelming number of boxes I've worked on had circuits both originally placed, and later added, without any sort of real forethought, so I know it is common to just pop breakers in wherever. Does it make a difference?

[@jeepernj99]
