PLEASE use copper wire (as opposed to aluminum). You might want to get 3G copper compared to AWG 4. I just bought some AWG 3 and it was 4 cents a foot more than AWG 4.

Copper is really cheap now. Yes, them ampacity of aluminum and copper can be assessed and made equal, but copper will never, ever corrode.
