Home | FAQ | GFCI/AFCI Outlets


Most homes are now built with two types of outlets: GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter). Both outlets are designed to trip if there is a hazardous condition detected in the home’s wiring. However, because of the outlet’s design, treadmills and incline trainers do not interact well with GFCI or AFCI outlets.


GFCI outlets are often found in bathrooms and kitchens, and are often identified by the red or white reset switch on the plate. GFCI outlets are designed to flip their breakers if there is too much power flowing through the ground port. Because treadmills and incline trainers use the ground prong on the outlets to disperse static electricity, if you plug your machine into a GFCI outlet, it will likely trip the breaker and shut down the machine. If this is occurring, move the treadmill to a different outlet. GFCI breakers often cover other outlets nearby, including outlets that do not have the red reset switch on the plate, so it is recommended that the treadmill is located in a separate area. It is also important that the treadmill is on a dedicated circuit.

AFCI outlets are designed to detect electrical arcs and will shut down the flow of electricity if they are detected. Treadmills and incline trainers may trip  in Treadmills and incline trainers may also have problems operating on AFCI outlets. However, homes are now required to have AFCI outlets to meet building codes. If your machine is tripping your home breaker through an AFCI outlet, recommended solutions include consulting an electrician, switching to a different model of outlet, or using a noise Tripp lite isobar.
