I have purchased a new subpanel for my attached workshop, and now I need to decide about 100-amp wire and conduit. I can either run three strands of #3 copper in metal conduit for the ground or I can run a 2-2-2-4 aluminum twist in larger plastic. The subpanel will be 50' from my main panel, and I will have four 90* turns along the way. The copper wire would cost me a little over $150.00, and the aluminum would cost about $50.00 less ... but then the plastic conduit for the aluminum would have to be larger than the metal for the copper ...
Also, I presently have a new and fine-for-now 60-amp breaker that might accept the #3 copper going to the subpanel, but I would have to buy a 100-amp breaker if I use the #2 aluminum wire.
Which way should I go?
