I have a detached work shop which I have installed a 100 amp sub panel with a few circuits to run lights and outlets (20 amp circuit breakers). I need to run service from my house to the sub panel. Hy house panel is full but I can run from a lug at the meter to the new building, approx 135 ft away. What size wire do I need?

The normal criteria for sizing wire is 125% of the max load. 100 amps X 1.25= 125 amps. #1 awg is good for 130 amps. If you are running under ground that requires up sizing the wire. At 135 feet you will have less than a 2 volt drop.

I called my electrician about 5 times. He wasn't big enough to get a deal from any of the local suppliers so I did all the layout, pulling and purchased all the wire. left about 6-8 inches hanging out of all the boxes, and about 2 foot on the main (following his suggestions) he came in wired for about $600. I live in town so i needed to make sure it was up to code.

I am @ 130, with 6 lights 7 110's 4 220's, and couldn't be happier, all the 220's are on their own fuse, this way the tig machine, doesn't mess with the lights or radio.

until i get that mill???
