Power Distribution HELP
Power Distribution HELP
(OP)
So I'm a young EE, and my boss quit and hasn't been replaced yet. Still have a job to do. Please help if you can.
I've got a system to set up that has a Utility feed to a building carrying roughly 1600A. There is no room for Switchgear, so I have to distribute the load to have multiple breakers feeding loads. To do this, I need some busbar between the utility source and the downstream breakers. Just wondering if there's a section of the code that outlines requirements for this installation. As in - DO I NEED TO PROTECT THE BUSBARS??? I don't know of a 1600AT breaker that's not in SWGR.
Any help/pointers would be greatly appreciated.
Thanks!

RE: Power Distribution HELP
Q1) Are you wanting to add a switchboard?
Q2) Sounds like you have an incoming utility feed and you want to "tap" it to feed another switchboard. The NEC talks about services in section 230. NEC section 240.21 talks about tapping circuits.
Good Luck!

Perhaps I didn't clarify the problem - the electrical room has only one means of egress and is not big enough for Switchgear. So my options are anything that is outside, or some way to distribute the loads without switchgear.

But also, this does not appear to be that large of a system, nor one with very high IC, likely 65kA or less. You could likely do this with a small switchboard instead of switchGEAR, it woul not take up much more room than the 3 separate breakers and bus bar and all that conduit, separation etc.

RE: Power Distribution HELP
Actually, the IC is a little above 80kA, which doesn't help the problem. I think I would still need a room with two means of egress for a switchboard, right?
