Question: Can 12/2 with Ground be used as a cheaper answer to 12/3 wiring?


Hi Eugene,

I think you know the answer to this. 12/2 and 12/3 are simple two different types of wire. The can not be substituted for one another. 12/2 has two conductors with a ground.
12/3 has three conductors with a ground.

If you need three wire then the 12/2 will never work.
