Can I Use 20-Amp GFCI On 15 Amp Circuit? You can''t use 20A GFCI on a 15A circuit because a 20A GFCI will draw more power than the 15A circuit can handle. This will cause the breaker to trip. If the breaker malfunctions, you could start a fire, especially if you are using that 20A GFCI to operate a 20A appliance. 15A GFCI Pros & Cons Pros

GFCI Outlet Troubleshooting Testing GFCI Outlets: Plug in a device and push the TEST button. If it works properly, the device should turn off, confirming there is no electrical current. It is recommended to test your outlets monthly. Resetting GFCI Outlets: In case of a trip or test, the RESET button is intended to return power to the outlet.
A GFCI outlet runs about $15, such as this Levitron GFCI Outlet (available from Home Depot). An electrician will charge an additional $50 to $100 dollars per hour to replace outlets.
