GFI in bathroom tripped and wouldn't reset, purchased new one ,after unhooking old one I lost track of which set of wires were line in and which set were power out to the outlets.. How do I determine...
Part of the problem is that the instructions showed the two recepticals with the ground plug in the up orientation for the hook up .the one I took out had the plugs on the bottom. I don't remember when I changed it out several years ago if it was the same and I just rotated the assembly when I put it back into the wall. Does it matter if the line in and out is reversed?
