Sorry didn't read all threads yet so maybe this came up maybe not, but is that actually a problem? Particularly if both are service disconnecting means?
I agree, show me what wire could possibly be overloaded if I feed one generator, with the neutral unbonded in the generator, to two panels, using 4 wires to each, that happen to have the neutrals connected together in the meter socket?
The generator (in this case given) has a capacity to provide 30 amps per leg (not per phase, that is a discussion for another time
![ROFL :ROFLMAO: :ROFLMAO:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
single phase you know!) and protects those two legs with 30 amp breakers. So the maximum unbalanced neutral current is 30 amps, even if a white becomes disconnected in a main breaker panel. 10 AWG wire. Why the discussion?
I too did the 2 200 amp panels because I could. Now after 20 years of joining circuits from one panel to another to get what the family needs to run, like last night when the power went out because of a fallen tree, and still not having light where needed, I'm ready to do the two interlocks instead of the 6 circuit Generac box from 20 years ago. And just manage loads as I do now, with my hands, but better.
