does the "2" and "3" mean the number of wires?
what is the 3rd wire for?
Kind of... A 12/2 has three conductors. A 12/3 has four.
fans or multi-switch lights?
Basically, I want have a few 220volt capacity outlets in my shop so I called an electrician. He said I could buy some "12 guage with ground Romex" and he would wire it for me.
I just don't know if i should get the 2 or 3 wire?
see that \/
For 220v you need the 12-3nmb with ground.
220v needs two hot wires and a neutral.
220 needs 2 hot wires and an insulated neutral, PLUS a seperate ground.
uh, that is what 12-3nmb with ground is....
And you don't NEED the ground to get 220. Just for code compliance and safety.
Is the brand Cerro Wire okay to use? I was at Lowes and they didn't have Romex.
As long as it is copper and has the protected sleave on it then yea.
Just cut the ground wire out. Everybody does it.
Just make sure it is labeled '12/3 nmb' and you will be fine.
