Copper and aluminum SEC

[Mike Lamb]

Is there any prohibition of mixing copper and aluminum for the SEC hots?

[Marc]

I don't see how it could be a problem, assuming all connectors and devices are listed for it.

[Erby]

I agree with Marc.

Right, just never under the same screw, in a case where 2 conductors are allowed.

The Al conductor needs to be the correct gauge, usually one size larger than the corresponding Cu.

I understood anti-oxidizing paste to be a requirement, but that could be just a Canadian thing.

It's not a requirement of the NEC unless the wire manufacturer or the panel manufacturer require it.
