Hello All,

I just installed a Generac 7,000 watt generator with a Connecticut Electric Switch
Energen Manual Transfer Switch Model 10-7500.
Two of the circuits on the Manual Transfer Switch are wired to supply power, in a power-loss situation, to two bedroom arc-fault circuit breakers in this Square D distribution panel. The Arc-fault breakers trip whever the generator supplied power is placed on the circuits.

Is it possible to wire to these circuits so as not to trip the distribution panel arc-fault breakers?
Is it likely that I have made a mistake????
Should these circuits be wired differently than all the others???

Thank you for your help,

Ron Gabaree,
Master Electrician/ Contractor

Verify that, in the transferred condition, the (one) neutral-to-ground bonding jumper is intact. [For a typical residential system, that should almost always be the case regardless of the transfer-switch position.]
