GFCI (Ground Fault Circuit Interrupter) or AFCI (Arc Fault Circuit Interrupter) outlets in your home and your exercise equipment don’t and probably won’t ever get along with each other. GFCI and AFCI outlets are designed to protect you and your home.
Due to the design, amperage requirements, and the way that electric motors work, if you find that your treadmill is tripping the switch on either of these types of circuits or outlets you will need to move your treadmill to a standard outlet or circuit.
GFCI – Ground Fault
As part of the design of your treadmill or incline trainer the ground is used to disperse a lot of extra static energy. This use of the ground will cause your GFCI outlet to trip the button every time you use your exercise equipment, and you will have to press reset.
AFCI – Arc Fault
Your treadmill runs on an electric motor. These motors as part of normal use may arc within the motor. This may cause the Arc Fault breaker to trip.
