I am building a 16x20 shed for my woodworking projects. It is about 80 ft from house. I am attaching power to existing electrical panel on outside of house. What size wire do I need to run to shed? I have a 100a main breaker panel in the shed, I am thinking with a 220 service and the tools i will be using are med. table saw(110)planer(110) ect..I need to bury it with plastic grey conduit 18 in in the ground(min). What do you guys think.
I googled "amperage distance wire size" and clicked on the first wire size calculator that came up.
For 240 volts at 100 amps, at a length of 80 feet, it recommends 1AWG copper.
