I'm planning to build a shed next spring, and want to make sure my thoughts on power are correct.
The shed is about 100' from the house, with another 20' inside the house to get to a subpanel. All I plan on having out there is some LED lights and a couple 120v outlets for convenience. The heaviest load I can foresee would be a leaf blower or maybe an electric lawn mower, if I ever get one.
Coming out of the house I'd go underground for about 15' to get under 2 gates, then I'd bring it up and run it on the backside of a fence, to save myself trenching the whole way.
With 8 AWG THHN wire I'm calculating a 2.62% voltage drop (down to 116.86) on a 20-amp load. Is this right, and sufficient? And I would need 3 conductors (black, white, green), correct?
How deep does my conduit need to be for the trenched sections? I'm planning 1" PVC conduit, is this good for both buried and aboveground sections? Any reason to go with a trench the whole way?
Any other tips? Thanks!
