I've removed a Lutron dimmer switch with the goal of installing a regular light switch. There are two romex sets of wires coming into the box. One set reads a normal 118VAC between black and white. But the other set reads nothing between the black and white wires but on that set, there is 118 VAC between the black wire and ground AND between the white wire and ground.
Why do the readings on the second romex set make sense? Where would they be getting power from? The power goes away from all of the wires when the breaker is opened.
Appreciate your explaination on these readings.
