How An Electrical Panel Should Look. : Cableporn - I'm not disagreeing with the middle of your declaration however the "never ever" part isn't real. Grounding and bonding is probably the most misunderstood a part of the nec so much so that there are publications handling just that subject matter. I've taken the osha grounding and bonding route and still should look things up now and again. In a industrial or industrial installation with a couple of mdps and ldps, you're 100 correct. In a unmarried residential panel, it's far perfect in step with the nec and i haven't come upon a unmarried municipal inspector who has asked for some thing different.
It as a minimum seems to be a subpanel so the you don't connect the impartial and floor collectively. If you bond impartial and floor together someplace apart from the principle carrier panel you effectively simply turned your ground line right into a neutral among there and the principle ground/impartial bond.
Honestly? In no way? I guess the 12 panels i swapped out at a coast guard facility closing summer season by no means happened. I know you weren't there, but who am i to question a man who honestly knows the whole thing.
It's a 3-phase panel, which means that every 0.33 breaker is on the identical segment. Happening the panel they land on segment 1, 2, three, 1, 2, three, etc. If you fit the wire colors this will be black, purple, blue, black, purple, blue... Approximately halfway down the proper facet, this sample is blended up, which means that that a blue and black twine is sporting present day from a unique section.
Surely they could have been switched round to provide a even load accross the levels, whilst going against colour conventions, this still shouldn't be an difficulty and except a impartial changed into tied to every other segment, you continue to could no longer get phase to segment. Notice how the large incoming wires are shade coded black-red-blue. And from top to bottom, the shade coding maintains. This is important to understand what section every twine is; a, b or c. If a wire is coded incorrectly then you could have large issues (e.G. Tying b phase and c phase together). Circuits 12 and 14 are incorrectly coloured.
