[Edited from original version apparently read into a cell phone's voice reco.]
I am trying to wire a dimmer switch into an existing light switch that was in the box before. It had three wires connected to it:
- a white wire which was labeled line negative on the old switch [NEUTRAL]
- a black wire that was labeled line positive on the old switch [ALWAYS HOT]
- in a red wire that is presumably the power wire To the light the light. [SWITCHED HOT]
The dimmer switch has a ground wire, a red wire, a black wire, and a striped red wire. According to the instructions on the dimmer the black wire should be connected to power; the red wire should go out to the light; the striped red wire should just be capped; and the ground should go to the ground.
What confuses me in the situation is that the white wire coming out of the wall doesn’t actually attach to anything. Is this correct? Do modern dimmers not need a negative [NEUTRAL] return?
