Aluminum + Copper Feeder

[Kenny Rigler]

Hey Guys-

This is the first time I've seen the combo of aluminum and copper on the feeder. I wasn't able to see a size label on the conductors. Any thoughts on whether or not those conductors are appropriate for 200 amps? Thanks.

Size looks fine for 200 Amps

AL would need to be 4/0 for 200 A service.

Copper would need to be 2/0.

Any thoughts on whether or not that's a 4/0 AL conductor? Same for the SEC going to distribution panel???

Kenny,

Look at this:

The Al and copper are fine as long as they're properly sized as Micheal outlined. Hard to tell if those are #4/0 Al or not from the photo's.
