So I was looking for a spot to connect a transformer for outdoor lighting when I noticed a blank off plate near the top corner in my garage. I popped it off and discovered 3 separate circuits going to it.
I figured a good way to start would be to connect my DMM and start flipping switches....
I only found one switch in my house that turns on one of the 3 circuits in this mystery box, its one that turns on the accent lights one both sides of the garage door..
How can I find out what the other two circuits are in this mystery box? Why would they put this mystery box here in the first place?
Thanks for any help!
