Scott,
The yellow wire is actually another extension cord... (I find these yellow flat cords attached to garage door openers constantly!) I'm starting to think they were sold with the openers! [Linked Image] The white wire coming from the FPE is attached to the neutral bus, goes out of the panel & swings in the breeze! Which BTW, the subpanel is doing as well... It's being held by a couple conduits, about 2 inches off the wall! [Linked Image]
