I'm not certain what house1 service is, but house2 is very likely 200A since it was installed just 10 years ago. House1 was built in the 19th century, so who knows when the last time service was upgraded. It has a fuse box instead of a breaker panel. The utility is PGE.

We've got a section of direct burial 10/3+G that is probably long enough, so maybe it's best to just use that. I doubt we need more than 30A to the garage. I should find out what is already running from house1 to the garage.

I'll have to look at what breakers are in there already. There's no sub-panel, and I don't know if one is required by code. We might have a sub-panel available though if one is needed.

So, if we run 10 gauge to the garage, can we also keep the existing run to the barn? As it is, I think it's just a single outlet running to the fuse panel of house1. Probably 10 gauge running to the barn, as that would explain how we have a leftover section. It's direct buried at 3 ft with no conduit. An online calculator says 10 gauge 120v at 400 ft has a 13v drop at 15 amps. That seems acceptable for a single outlet providing minimal lighting.

I know it's a big no-no, but I'm going to try running cat5 in the same 1" conduit to the garage. Don't need a lot of bandwidth, just 2 PoE IP cams. If it sucks, I might try shielded cat6.
