I am wanting to do a run from my garage to a future site for a slab. the length is about 80 feet or so and the slab will hold about 200 amps (going to be half shop and half billiard room-- basic 110 outlets, one or two 220 outlets, and lighting). my father-in-law has about 100 feet of 2/0, maybe 1/0, aluminum cable, leftover from Entergy, the local utility company. It's the same wire they ran from a transformer to a outside breaker box and then about 50 ft underground to go up into a mobile home.

I was always taught to use copper wire but here, the utility company used aluminum and there's plenty left over to do what I need. Is it okay to use it?
