The electrical inspector just left and I passed, but there was a glitch and my heart stopped beating for what felt like an hour.
I ran a 1" pvc conduit with four #8 wires for the generator inlet and 3 #10 for a 20 a,p cpnvenience outlet, lighting, etc. Oversized it for distance. Plenty of room in the pipe for that, here's the handy conduit fill calculator that tells me that:

He knew there was a problem with feeding more than one circuit to a building on the same property but didn't have a code book handy. Imagine - an inspector that didn't carry a code book. Nice guy, knowledgeable but looked like he just rolled out of bed. So I grab my 2014 code book and the magic pop-tart and I pull up the relevant section 225:
Multiple structures
Where more than one structure is on the same property, each must be served by no more than one feeder or branch circuit [225.30]. As you might expect, the NEC provides several exceptions.
The first one is “Special Conditions.” You can provide additional circuits for:
- Fire pumps,
- Emergency systems,
- Legally required standby systems,
- Optional standby systems,
- Parallel power production systems, and
- Systems designed for connection to multiple sources of supply for the purpose of enhanced reliability.
Thank The Great Magnet for that exception, I was thinking of maybe crying, pitching a fit, speaking in tongues, hurling around great clods of my own feces ..... the usual .....
The alternative would have been to put a small weather rated panel down there @ 30amps and pull the generator inlet out of that. That would mean wasting about $125 and plenty of materials. So, I gave the nice man the exception and his $110 and they will close my permit out at the town hall. Whew !
