ECN Forum Forums Code Related Discussion NEC & other Code issues Outside Disconnect

Home owner doesn't want outside disconnect
for 12,000 watt natural gas generator
on the side of his house.
I can't find it in the code book that states
it is required for a backup generator.
Air conditioners require a service disconnect
ect.. but help me with generator code please.
Thanks Rob

445.18 Disconnecting Means Required for Generators.Generators shall be equipped with a disconnect by means of which the generator and all protective devices and control apparatus are able to be disconnected entirely from the circuits supplied by the generator except where:
(1) The driving means for the generator can be readily shut down; and
(2) The generator is not arranged to operate in parallel with another generator or other source of voltage

Thank you sir.

Please don't address any of us as 'sir', we are all friends.

The 445.18 disconnect is usually mounted on the generator. I would think the 225.31 & 225.32 is the applicable section at the house.
