Comment Comment by amluto Indeed. Maybe a new generation of aluminum wire could be better.But for big feeder wires, it’s a different story. Compare:2 AWG XHHW-2 Al: 0.358 inches OD, 0.081 lbs per ft, $0.90/ft4 AWG XHHW-2 Cu: 0.33 inches OD, 0.129 lbs per ft, $1.78/ftI know which one I would pick under most circumstances. And insurance companies are just fine with the aluminum option. parent amluto 4 years ago
