Looking at an electrical box (wall switch box) - helping a friend.
How would it happen to see one wire at 120VAC and another wire at 280VAC?
This is with VOM checking 3 wires in conduit. No color matching here. (no white or black wires and only blue, red and orange wires?)
Wire 1 - wire nothing except one time saw a 120VAC load using metal box neutral
Wire 2 - 120VAC load - using metal box neutral
Wire 3 - 280VAC load - using metal box neutral
Used box once for neutral and saw the above loads.
I have never seen anything like this before.
No neutral wire in box that I was able to test with VOM.
