Hi, all.
Great forum community. I am seeking a little "affirmation"... If I have a main breaker load center sub panel with 4 critical breakers and install a generator inlet circuit / breaker and a generator interlock plate in this sub panel to isolate it from the main panel / main feed when enabling the generator breaker to feed only the sub panel, is this code compliant?
Let me know if I am not clear. I was told by a contractor this proposed set-up was not compliant unless I replaced the sub panel with a Gen Tran switch. Thank you in advance.

Depends on your city. Some cities do not allow cam and slider interlocks in panels for backfeeding by generators via a side breaker.
Otherwise it is generally okay to put the interlock kit in the subpanel pretending that the subpanel was the main panel.

I'd say yes because you are isolating the subpanel from the main panel and only powering the circuits in the subpanel via the generator. Provided your locality allows interlocks.
