You are watching: 12-2 vs 12-3


I am removing a wall surface and need to re-route some wiring. My plan is to install a junction box and re-route the wire together necessary. The concern I have actually is what type of wire do i need for one outlet. The existing cable is stamped 12/3? (from what I deserve to tell; hard to read). I thought that 12-2 was what i would need for an outlet. Is this correct? go it do a distinction if the outlet is in a series of other outlets?Thanks
XX-2 would have one warm conductor. XX-3 might have 2 hot conductors, a black and also a red.Typical consumption for xx-3 is 3 means switching or as soon as 2 circuits space run come the same location in one cable and also can be separation off at a junction box.

Thanks Jim! That"s what i thought..just don"t know why the cable would certainly be stamped 12/3?? over there are just three wires (not certain of color..not in ~ home).
another question...maybe i am not knowledge this..would you usage 12/3 if you room running a variety of outlets in line?

you wouldn"t unless:1) the receptacle is semi regulated ( height or bottom section controlled by a switch)2) you have two circuits in the same area ( black color on one breaker, red on one more breaker and also sharing a neutral) That method you only need to run one 3 wire cable rather of two 2 wire cables.Edit: ns not sure if you"re in reality talking about receptacles or light outlets..alot of ppl speak to recpetacles, "outlets"
