Can 2-poles be used on a 3-pole breaker?

Can 2 poles be used on a 3 pole breaker with the remaining 1 pole not used / unconnected to any conductors?

Why not!

I'll even venture to say you can use just ONE pole.


Better yet, it's legal to use NONE of them.

Yes you can use 2 poles of a 3 pole breaker although it may raise the eyes of an inspector.

Thanks. I couldn't find anywhere where it wasn't allowed. The conductors would still be protected in accordance with their ampacity. Figured article 240 would have been the place to not allow it.

Can and do.
