Electricital question
FACTS:
I need to run about 190' from breaker box to my shop. I have a double pole breaker on a 200 (+ or -) v. that says 30 on each leg. In the shop, I will be running a SP175+ 220v MIG Lincoln welder rated at 22 amps, but that only when cranked fully open. Most of the stuff is half that. I will be running about four shop lights, radio, and a power tool or two at any given time. My electrician buddy has suggested IIRC a #6 wire. Does this sound adequate? Do I get the bundled wire, or use the separate strands? How much voltage drop on that far? Is #6 marginal, or should I slightly oversize? Mike (my electrician) will put the right thing, but I just wanted to start shopping and getting prices together. BTW, does anyone know what #6 copper solid strand goes for now? There would be just about a 200' run. I did get about 800' of 2.5" underground conduit for free, so that helped. Steve |
