Do I have it correct that I should be using 10/2 w/ground on a 30A circuit?
I'm going to run new cable in conduit out to my shop, from my house. The current circuit is a 20A single pole with 12/2 UF running approx 40 feet to the shop. I notice when I have the lights on, and start the table saw or air compressor (not commercial grade), the lights dim pretty badly. I'd like to alleviate this by bumping up the service out there. I won't be running anything more than 120V, but I'd like to be able to have some overhead for when I'm running multiple machines.
Does this sound reasonable?
My plan is to put a 30A breaker where the 20A is now, and run 10/2 w/ground UF cable to the exterior wall, go through the sill to a weatherproof box, then down through buried conduit all the way to the shop, coming up the outside wall and through the wall of the shop...all in plastic conduit. From there, I would place a junction box. The 10/2 would be split at that point...one branch for lighting, the other for outlets.
Any thoughts on this? I'd run a feeder out there, but that would add significant cost, and my main panel is already full...no room for another double-pole breaker.
Thanks for the help.
