I am trying to puzzle out in the event that setup We’m contemplating will be NEC rule compliant.

I realize that backfeeding the panel that is main limited al green singles by 20% regarding the panel rating, in order for a 200 amp service may have an optimum 40 amp backfeed breaker.

Nevertheless, the things I can’t find is given information regarding feeding into a generator panel that is on a transfer switch. For me, if you should be “backfeeding” into that panel only once the ability is not on, would not it is rational you could backfeed any amount up to the utmost generator panel score? And, the only path that power would surely even arrive at the generator panel will be by switching the manual transfer switch far from grid power up to backup energy.

I recently aren’t able to find any information or paperwork with this situation however, thus I had been hoping someone here may help.

My recommendation, would be to draw an easy 1-line block diagram showing exactly how your circuit is wired and in which the energy sources/consumers are. Continua a leggere Backfeeding breakers for a generator panel
