While measuring the current at the circuit box for the posting above, I
noticed that one of my 20a breakers has a #14 wire attached to it. The only
thing on the circuit is a refrigerator that draws 7a to start and 1a to run.
As a practical matter, just how dangerous is this? The only outlet on the
circuit is in a position where it could not possibly be used for something
else by accident, so the only problem would be some weird overcurrent of
more than 15a and less than 20a in the refrigerator; and that just doesn't
It would require replacing a double breaker, so it would be about $10. Yes,
I realize that is cheaper than replacing the house.
