Al,
Just the usual concerns with aluminum conductors. A little light =
corrosion in an aluminum connection has a lot of resistance, whereas a =
little light corrosion on copper adds only slight resistance. Extra =
resistance causes heat, which accelerates corrosion. A vicious circle. =
Therefore, you need to make extra certain you do what you can to prevent =
corrosion at the connections to an aluminum buss. Special coatings, =
etc. On balance, I don't think it's worth it - I'd get some more =
copper!

Subject: REFLECTOR:Buss material
I had some 1/8" copper buss material that I used most of for ground =
buss. Any reason not to use 1/8" aluminum for circuit breaker buss?
