1000 amp gfi protection

[wmthompson90]

How does one know if gear has gfi protection? Working with gear from Germany and waiting on unit specs.

GFI or GFPE?

It won't be there unless someone specifically specified.

GFI or GFPE?

Most manufacturers and engineers call it GFI when the trip point is above 30ma, which would be the case with a 1000A circuit.

I am willing to bet they did not. I have a temp on main inspection tomorrow and even if the inspector does not catch it, i will have to bring it up to him. We did not provide the gear yet rushed for power.

what the code requires for 1000 amp or greater.

So my answer to the inspector would be "yes if its programmed"?

Don't you have drawings of the gear if it is being temped tomorrow?

nvm i understand that was your reply to infinit and not my answer

i have one lines. no drawings on the gear. my scope was getting power to it and another contractor taking over from there.

I thought of the gfi protection a little late and requested gear drawings 2 days ago.

what the code requires for 1000 amp or greater.

210.13, 215.10 or 230.95 depending on the circuit being a branch circuit, feeder, or service. Note that this only applies to solidly grounded wye systems having more than 150 volts to ground but not exceeding 1000 volts phase-to-phase.

Isn't 30 ma the threshold for GFPE?

This is a 480/277 wye system/systems

The 1000amp gfi rule applies. There is no hazard had something trip(rules out the exception).

That may only be part of your problem. You need to assure the gear had acceptable NRTL certification.

 

[wmthompson90]

I started in the trade in 08. I’m still green I guess. I’ll google it after this reply. I don’t know what that is or recall it in a code reference.

I’m not use to gear coming from overseas. I have learned something from you more than once now. (Grim reaper) thank you
