Want to change a switch that now goes to an outlet to a double switch and add a fan (no light). How to wire?

The switch currently has a black, white and green wire. The replacement double switch has a green, 2 black and 2 gold screws. opposite each other.Want to change a switch that now goes to an outlet to a double switch and add a fan (no light). How to wire?ok, Green is your ground black is neg and white is postiveWant to change a switch that now goes to an outlet to a double switch and add a fan (no light). How to wire?This cant be done if you only have 2 wires in the box ( green is ground) this is called a switch loop where one wire from the switched outlet feeds the switch then loops back to switch the outlet on and off ,there is no neutral wire in the box which you need to operate the fan, you could come out of the outlet box and then go to the fan but that will switch the fan and outlet at the same time or you could do fan only.

The switch you have sounds like a 4 way switch not a double pole switch, if there is no on or off printed on it then it is a 4 way just so you know.

If you have any ? you can e-mail meWant to change a switch that now goes to an outlet to a double switch and add a fan (no light). How to wire?Assuming the current wiring was installed correctly...



Besides the white (neutral) and green (ground) wire, you should have two black wires in the current switch box, both connected to the current switch.



One is an always %26quot;hot%26quot; wire feeding the switch, the other is the switched leg that goes from the switch to the receptacle to provide power only when the switch is in the %26quot;on%26quot; position.



The new double switch will act like two separate switches getting their power from the one existing hot wire, so connect the %26quot;hot%26quot; wire to both gold screws of the new switch.



One of the black screws on the new switch will be for for the switched leg to feed the receptacle, and continue to turn it off and on. Connect the other existing black wire that was not hot to it.



The other black screw is for the fan. You need a new black wire to connect to this screw, which black wire you also need to run to the fan. Along with it, you also need to run a new white and new green (or bare) wire to the fan. This can be done with a 12/2 with ground. (the ground will be bare, that's OK)



Connect the green wire in the box to the green screw on the new switch, and also connect it to the new green (or bare) wire you need to run to the fan.



Connect the white wire in the box to the new white wire you run to the fan.



Once you have made the wire run to where the fan is to be installed, connect the new black, white, and green (pr bare) wires to the fan. You now have a switched fan circuit.



PS Ignore the suggestions from the two previous guys, and...



to BigJoe, you are referring to DC with %26quot;positive and %26quot;negative%26quot; talk, which would not apply here;



and to brndnh721, dude, what are you smokin', if you really are an electrician, re-read the question.
