    How do I get 100 AMPs to my Garage
    I would like to wire a 100 amp service to my garage. I have a 200amp main entrance box in my house and would like to get power to a panel box in my garage. The panel box I have to put in the garage has a 100 amp main disconect with 12 cicuit spaces. Questions:

    Can I simply put a 100 amp breaker in my 200 amp main box and run a cable to the 100 amp diconnect in the garage box?

    If yes what size cable (total distance about 60 feet)?

    Thanks for any help.

    Yes install the 2 pole 100 amp breaker in the main panel. The feeder to the garage panel can be either 3- #2 Al for the two hots and one neutal and 1- #4 for the equipment ground. Or you can use 3-# 3 copper for the hots and neutral and 1-# 8 for the ground.

    Be sure to isolate the neutral and equipment ground at the sub panel. The neutral is already insulated, just be sure there is no main bonding jumper, which usually is a screw that is driven through the neutral bar and threads into the panel backbox. The equipment ground must connect directly to th backbox, along with all the equipmnet grounds from the bracn circuits.

    If you have any other questions, please get back here with them.
