Troubleshooting

Two years ago you had a bathroom electrical problem....Plumbing delivering a shock.......did you ever resolve that one ?

The bath is a special circuit....adding the bath fan may not be allowed.....what does the circuit feed ?......any GFCI protection ?

I assume this is a digital VoltOhmMeter.....have you metered the incomming service at your main.......

Fuses or Circuit Breakers ?

IF the service voltage is Normal AND the voltage is High in the bath.........there is a cross connection to another circuit......The circuit is wired in SERIES with another circuit......with a potential of 220 volts split between them......

Maybe the neutral bar is cracked in the panel.....

Could be a multi-wired circuit problem (shared neutral)......

And the Original problem sounded like a bootlegged neutral......

One way to attempt to find the cause is to Monitor the voltage in the bath while flipping circuit breakers......I'm betting Two different circuit breakers will affect this receptacle.......

(Run an extension cord from bath to the panel an observe voltage on the cord)

"......measure Once.....cut Twice....
throw that one away and cut a new one...."
