If you already have a location for the second switch, and it has power, then you don't need to run any additional wires. You can use the old work (wing) boxes for putting an electrical box into a wall that is already covered with drywall. The only additional wiring you need, is to get a feed to wherever you want the second switch, using a 14/2 wire. Then you only need to run a 14/2 feed to the second switch location.Įxisting/Replacement- If you want to add a 3 way switch to an existing light switch, then you don't need any additional wiring at that location. New- If you are adding a new switch, then you run the 14/2 from the light, and a 14/2 from the electrical panel, or from a sub feed, into the same box. Similarly, 14/3 has a black, a white, and a bare ground wire, but includes an additional red conductor, hence the 3 in the name instead of the 2. 14/2 wire has two power carrying conductors, a black, and a white, plus a bare ground wire. You will need 14/2 Romex, and 14/3 Romex. You will need two different types of 14 AWG wire, to wire your three way switch. Keep it at 12 Amps or less when using 14 AWG wire and standard 15A three way switches, to be safe. This will give you the approximate number of Amps.
