Splicing main service wire (aluminum)
I'm wanting to make a change in my house that would mean moving the breaker box about 6' further from the meter. I'd like to avoid running a whole new service wire and I was told that it's legal to splice them. This is a 1960 era house and the splice would take place in an accessible attic.
While I've done a fair amount of wiring (for a carpenter) and I understand wiring basics, I've never spliced aluminum wire or any wire this big before.
I'm just starting to research the proper method and am asking for advice/direction here. I've been reading about parallel groove connectors and sealants, etc....
Thanks for all help,
