Fixing overly-sensitive AFCI circuit breaker? (not GFCI!)
Because of the commendable wiring job by Torbel's contractors, the plugs in both my bathrooms as well as along the outside walls of both bedroom are all on a common circuit, protected by a GFCI breaker. because of this, all my computer and AV equipment is plugged into this circuit.
The problem I'm having is that almost randomly, the breaker trips, cutting power to the circuit. For about a year it had stopped (only happened every 2-3 months) but now it's back to 4-5 times a week. Very often it happens 6-8am, so I'm thinking it could be related to voltage fluctuations from the grid.
Is this normal behaviour? Is it possible the GFCI breaker is defective or too sensitive? Any suggestions on what I can do to troubleshoot this? Aside from that all the equipment on the circuit is operating normally. It's getting annoying to come back home from work and find all my equipment off and UPSes drained..
