replacing double switch (with two circuits) with single pole on/off and dimmer switchReport
Please briefly explain why you feel this question should be reported .
Hello. Please see included photos as you read my details.
I currently have a double switch in a bathroom. Two different circuits power this switch- one for the lights and one for the fan. In the switch box, excluding the ground wires, there are two white wires feeding one side of the double switch. On the other side of the switch, two black wires are feeding that side. The bottom white wire is the incoming hot wire for the light and the top white wire is the incoming hot wire for the fan. The bottom black wire is powered when the bottom (light) switch is activated. When the top switch (fan) was activated, neither top wire (black or white) showed voltage on my meter. I do not know if that is normal or not but I got no read from either top screw when the fan was running.
Anyway, I am replacing that double switch with a single pole on/off switch (for the fan) and dimmer switch (for the lights). This new switch has three screws- a black screw for live, a switch screw, and a dimmer screw. It also has a ground wire attached.
On the new switch, the “dimmer” and “switch” screws are outgoing to the actual light and fan, right?
The live white wires coming in from the breaker box should connect to the black “live” screw, right? If I twisted both white wires together, wouldn’t that give power to both circuits, even when one is off?
Any help would be appreciated with this project. I have replaced light switches and outlets before but I am really questioning this one.
