Electrician

I know a few of you are experienced electricians on the forum from some of your posts. Hve some pretty specific NEC code questions not related to residential systems. Can someone ping me with a PM?

Side show and maybe ray will be along shortly


I hate the pm me threads I want to hear about your internal dilemma trying to bring in 440 3 phase into your town house so you can power your giant machinist tools or 200 gallon whiskey still.

My post is in regards to the supply side boning jumper on a three phase 480 volt system supplied from a ungrounded delta-delta transformer. Just didn't want to bore everyone on the forum.

Yes! Thank you I have so many terms to research now.

Last time I played with 3 phase was getting a 9 wire in a 50 amp circuit to rotate the right way.

edit to add 3 phase 480 is scary. 120...just tickles. 240... keep one of your hands behind your back. 480 no bueno

I offered to sell you a whole shops worth of three-phase stuff but nooooooo.

I can tell you all about three phase, but I have a feeling that I will loose respect for how much of a nerd and dork I'am over this stuff. But hey I do it for a living and it pays really well.

Worst I experienced was a 115kV fault which wasn't fun.

there are some many nerds here. In all disciplines. Ask a question and someone is a professional

Can you ask your same question but instead of delta wired could it be wye? If not why?

If one of the requirements was tear down this external wall to load the tooling that’s way above my skill level
