T. Keith T asked:
My power company is now charging over $400 a year to provide power to an outbuilding on a separate service. I would like to feed this outbuilding with a sub-panel from my house’s 200 amp, 42 breaker main panel. I need 60 – 100 Amps +/- to power my wood shop. It is a 200′ run (total l.f.) from my homes service panel. What size wire would I need to run (underground) to feed my work shop (30 Amp table saw, one (1) 20 Amp conv. recp. circuit and one (1) 15 Amp lighting circuit). Other tools would never be run with table saw.
Honest…honestly
