Hey, all, I have two estimates for installing the NEMA 14-50 outlet in our garage for use with the UMC. The main difference among them is the choice of wiring.
One is proposing to use "#6 Romex," which I assume is 6/3 copper, for $450.
One is proposing to use "#6 SER AL wire type XHHW," which is aluminum and rated for 50Amps at 75'C (per http://www.barr-thorp.com/wp-content/uploads/2011/04/Digest-176-NEC-Tabl...), for $350.
I'm not very jazzed about the idea of aluminum wiring. Anyone with electrical experience have some advice or opinions?
Thanks in advance.
