I'm trying to change my light switch to a Leviton dimmer switch (4).
I checked with a voltage detector pen...
- Both bottom two wires connected with my old switch has power when switch is off. Does that mean there are 2 hot wires? How do I connect it with the dimmer?
- The upper wire connected with old switch has no power when switch is off but has power when switch is on. So I assume it is the load wire.
I can't find any ground wire connected to old switch, but there is a red wire in the wire box connected with nothing. Should the ground wire to connect with Leviton green wire?
