I’m probably going to call an electrician to install in these locations, but I thought I’d post here if anyone had some insight. I inherited a house with two Lutron Maestro switches in the same room that independently control two sets of recessed lights. I figured they would each be a 2-way switch and I’d be done in 20 minutes, but I was wrong.
The light switches are flanked on both sides by electrical outlets, not sure if that matters. Here are pictures of the wiring, first the left switch and then the right: Imgur: The magic of the Internet
The left switch seems normal, but I have no idea what’s going on with the right switch. After some googling I thought maybe they repurposed the white wire for hot, but I tested it with a multimeter and got weird readings. Line-side the white wire is at 20v above ground potential, and load side it’s at 0v. The left side switch has a bundle of white wires capped in the back which I assumed was neutral, but on further inspection it looks like those white wires are also tied to the white wires that feed the right switch. Indeed, the black wires in the left switch are tied to a cap in the right switch as well, though I’m realizing now I should have done continuity testing while I had the power off.
I’m not an electrician but I haven’t seen anything like this while prepping to install my switches; so far I’ve got three in the house and they were all pretty straightforward. Does anyone know what’s going on with these?
