GFCI tripping when tv is turned on from a different circuit
I have gfci tripping when I turn a big screen tv on from a different circuit. A vacuum doesn't cause the gfci on a different circuit to trip.
This is a 1940 home with all BX wiring. Some years ago I replace all the outlets putting a gfci in the first outlet for each circuit.
There was an odd two prong outlet that did not have the usual side by side inserts for a two prong plug but rather one of the inserts was at an angle of about 45 degrees. I simply replaced it with a gfci and this is the one that trips when I turn a large screen tv on from a different circuit. Interestingly the tv circuit's gfci does not trip! Just the other or second circuit?
