I am running a 100 amp circuit from an existing building to my new garage/shop. The feeder panel has two hots, a neutral buss and a separate equipment ground. Total length between panels will be a maximum of 65 feet. I plan to use #2 copper for the two hot wires (red and black). The neutral (white) will be #_____copper. The ground (green) will be #_____ copper.

Fill in the blanks for me.

Not looking to "get by," but don't want to spend more $$ on wire than necessary. Not looking to use aluminum - almost tragic experience.:eek

Thanks for the help!
