Wire and Panel for Workshop
I need some help. I have a workshop that needs to get power re-connected. Our septic repair guys accidentally tore out the electric line and now we need to fix it. I am new to this and have never posted before so I apologize if I use the wrong lingo.
The 1" conduit is still in place and can probably be repaired. I have an electrician who said I can put new wires back through it (3 wires #6 and 1 wire #10 THHN). However, this looks like an opportunity to upgrade to me. But to what is the question.
The shop is 800 sq' and I will primarily be using it as a 1-person shop, with woodworking, ceramics, whatever. I figure I need 2 15-amp circuits for lights, and 1 20-amp for outlets, and then I thought I would put each stationary machine on its own 20-amp (table saw, router, kiln, etc.) though I think those will just be used 1 or 2 at a time. So do just add that up? It looks like I need 70 amps (before voltage drop). Oh, and the shop is 138' away from the house, so I know there will be some voltage drop.
So what if I put in a 100-amp subpanel and run #4 THHN back through the 1" conduit (3 wires) and a #10 for ground? Does that sound right? Will that still fit in my conduit?
Any suggestions would be helpful.
