I am planning to install a 12KW standby generator for a residential, but instead of choosing certain circuits to be on the transfer switch i have recommended to have a transfer switch without a load center so the whole house will be served by the generator. The generator will be protected by a 50A main disconnect and the customer knows that are limited to only 50Amps

But am i correct to say that 702.5(b)(2)(a) will prohibit this installation that i have proposed?

(2) Automatic Transfer Equipment. Where automatic transfer equipment is used, an optional standby system shall comply with (2)(a) or (2)(b).
(a) Full Load. The standby source shall be capable of supplying the full load that is transferred by the automatic transfer equipment.


Be kind to your neighbor, he knows where you live
