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

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.
