I am racking your brains on in the event that setup We’m considering could be NEC rule compliant.
I realize that backfeeding the panel that is main restricted to 20% for the panel rating, in order that a 200 amp solution might have an optimum 40 amp backfeed breaker.
Nonetheless, the things I can’t find is information on feeding in to a generator panel this is certainly on a transfer switch. I think, that you could backfeed any amount up to the maximum generator panel rating if you are «backfeeding» into that panel only when the power isn’t on, wouldn’t it be logical? And, the only path that power even would arrive at the generator panel is by switching the manual transfer switch far from grid power up to power that is backup.
I recently aren’t able to find any information or documentation with this situation however, thus I had been somebody that is hoping may help.

Re: Backfeeding breakers for a generator panel
I will be having a little bit of a time that is difficult your connections.
My recommendation, will be draw a simple block that is 1-line showing just just how your circuit is wired and where in fact the power sources/consumers are.
Essentially, from my understanding, you will need to locate straight right back all power sources (AC Line, Generator, Grid Tied, etc.) types of energy as well as for an installation that is commercial none of the places should complete up significantly more than the rating of this breaker panel/bus bars. For the system that is residential none of these points should soon add up to significantly more than 120percent for the box/bus club rating.
