I’m racking your brains on in the event that setup We’m considering is NEC code compliant.
I understand that backfeeding the panel that is main limited by 20% associated with panel score, to ensure a 200 amp solution may have a optimum 40 amp backfeed breaker.
However, the things I can’t find is given information regarding feeding into a generator panel this is certainly for 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 method that energy even would reach the generator panel will be by switching the manual transfer switch far from grid power up to power that is backup.
I simply aren’t able to find any information or paperwork with this situation though, and so I ended up being 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 an easy 1-line block diagram showing just how your circuit is wired and where in actuality the energy sources/consumers are.
Basically, from my understanding, you will need to locate right straight back all power sources (AC Line, Generator, Grid Tied, etc.) sourced elements of energy as well as for a commercial installation, none of the places should complete up significantly more than the score for the breaker panel/bus pubs.
