GFCI Outlets and Nuisance Trips With Inductive Loads
Background: Bill, a Homeowner from Londonderry, NH
Question: I installed a GFCI outlet in my attic and ran the load side wires to a new, through the wall, Broan 6″ round exhaust fan via a wall switch. The GFCI seems to trip occasionally when the fan is turned off.
Not sure what to look for?
Thanks for your electrical question Bill.
GFCI Outlets are known for causing nuisance tripping for inductive loads such as:
Motors, Refrigerators, Freezers, Whole House Vacuum Systems and other devices that have an inductive load.
GFCI Protection is not required for specific dedicated circuits for such devices, however the outlets for these devices should be Single and not Duplex which would prevent using the second outlet.
NOTE: This is NOT true for GFCI protected equipment such as Jacuzzi Tubs, Spas, Hot Tubs and other such devices which are used in the presence of water which are usually protected by GFCI Circuit Breakers
