You are a smart electrician i was in the game for 34 years and im glad to watch your videos do it right the first time

Nice job explaining this. It’s important for this to be wired correctly especially with that much voltage and amperage.

Maybe get rid of the background music first while trying to explain something like this. Thanks for the effort though

[shanemcdaniel]

It does get overwhelming thanks for this video

Wow, terrible install. Thank you for the information on how this is all wrong and how you corrected it.

Full load amps won’t go to the other panel without any load. I’m not saying it’s a wrong setup. The feeder protection is defiantly undersized. I’m just saying.

You scared me when you touched that bus. Cause those main disconnects I think are on the on position. But I dont know whats feeding that, and if you locked out there. But there seems to be a working restaurant behind you. So it scared me when you touched those bus bars. LOL
Be careful bro.

Is that transformer feeding more than one panel???

[DavidBerquist]

Hay great video im proud of you i do lots of wiring my self i put pictures up on youtube and face book i use a trypod and if in small space i took a selfie stick to a big clamp and use my phone to record. I have 3000 electrical wiring videos i hope you get to look threw them consult codes before doing wiring i think your a bright young man keep up the good work let me know if you like my selfi stock idea

Great job! Would it be possible to use a bigger wire instead of a new transformer

[golife]

Great job! Would it be possible to instead of adding a transformer just use I bigger wire and a disconnect breaker?

Freddyamerica, how can I get a hand book to read about 3 phase 480/ 277, high delta conections??

[jartoliapackmech]

we supply the machine to him but machine require 480v, and they set-up transformer but he couldn't get 480v from transformer. please sir help us its request to you.

[Useertsjnradjz]

Please help
Hi guys,
I have tons of 277v light that needs to be installed but I'm not sure which gauge wire, circuit breaker and electrical panel to get. Please help!!

They used a pass through lug to another panel.

How many panels can you feed in parallel my friend? I know when you’re feeding in parallel you have to use the same type of cable etc but I don’t know how many panel you can feed with the same voltage

[dedofofo]

Sorry to say that, but you’re explanation. It’s really fast and you can explain it better.

[aten]

I don’t think you know what you are doing either . Guy had that right other then he didn’t put Breaker on sub panel. Just because on panel says 225A that doesn’t mean it’s 225A it is rated for 225A. So he had 1x 400A 480v with Sub panel probably 150/125/100A for lights. Transformer then 1 400A 208Y with Subpanel. You need to know the demand.

Hard to explain how to wire a panel correctly in a 4 minute video.
