That person appears to be unaware of the requirement that applies to feeders (as others have cited already). There is a similar requirement for services. But your distribution panel is not a service panel, so that would not apply.. . . the other is telling me that since it is not a service entrance that the MCB doesn't have to be GFI.
That is true, I think, perhaps, maybe a little. :grin: Do you know if there is a breaker upstream of you new D/P, but downstream of any transformer, that has a GFI device?One is telling me that the MCB needs to be GFI because it's over 1000 amps. . . .
I'm bad about reading more into something than I should but in this case exception 2 states in part: Exception No. 2: The provisions of this section shall not apply if ground-fault protection of equipment is provided on the supply side of the feeder
It appears to me that applies precisely to the OP's situation. Am I "under looking" this time ?
No, but we are all making an assumption that there is, in fact, GFI protection somewhere upstream. There should be, I suppose, and if there is then this new panel won't need it. But the presence of upstream GFI protection needs to be verified.It appears to me that applies precisely to the OP's situation. Am I "under looking" this time ?
It does not. There is a switchboard upstream, and the one-line only shows the feeder breaker on that switchboard and the feeder to the new D/P. We don't see the main breaker on the switchboard, and we don't have any breaker setting information (such as the annotation LSIG on the main).does his attached schematic not show a GF upstream ?
