House is ~50 years old. Copper Wiring. On one 20a circuit there are a number of duplex boxes. On three adjacent to each other the voltage reads 120 -- ~40 -- 120. The previous owner switched one box to a single receptacle and switch. And wired to the switch a lamp (incandescent) in a new skylight. The operation of which has always been problematic.
I tracked down the low voltage recaptacle when I move the refrigerator plug to that outlet.
Any thoughts on this? Thanks.
Does that 40V outlet work at all? Are you measuring it under load? Are you using a digital meter? I suspect that outlet may not be getting any current, but still will show voltage on a sensitive digital meter. A quick check using an old analog meter would tell you what is happening?
IMHO, not your electrician, you have a wiring problem, that should be looked at. Low voltage conditions can be detrimental to your equipment.
Now if I was there, my first step would be to toss in a circuit checker. The proceed on based on the results.
Good luck,
