hi

I will be building a shed and want to run 100 amp 240v service into it
from my house (house main is 200 amp).

what gauge wire do I need? it will be about 145 feet ( 60 feet
underground in conduit)

#3 copper or #1 aluminum, minimum, and make sure you run four wires (2 hots,
neutral, and ground) -- but why 100A in a shed??
