I took some photos and checked out specs on what's currently installed. It's way more crackpot than I had realized, so meeting code from house2 to the garage hardly matters.
house2 (new house) has 200 amp service on a pole at the corner nearest the garage, and the 1" conduit is already in place with a pull string (bailing twine). I think I just install a 30 amp breaker in this exterior panel and run my 10/3 UF-B to it.
house1 Has 100 amp service. Check out the photos to see how jenky it is. I think the siding of the house is just asphalt shingles. Didn't seem like a crapshack when I was growing up.
The garage currently has a 20a 240v and 15a 120v breaker fed by 10/3 from the old house. I guess that wire is spec'd to 30a.
The barn has the same 10/3 wire running from the old house to a switch, which then feeds 2 light bulbs and 2 receptacle boxes.
Here's the rub, the old house has separate circuits running to the garage and to the barn, so you can run max load at any location without affecting the usable load at any other location.
If I feed everything in series from new house, to garage, to barn from a single 10/3 line, then concurrent loads all add to the 30a limit. Not a huge deal since the barn is rarely used, and has very small loads.
Now, do I pull the cable with the bailing twine, use a heavier yellow poly rope, or see if I've got a fish tape long enough?
