Does a sump pump need a GFCI?

There is no NEC requirement for GFCI protection for a sump pump. The 2008 NEC removed the exception for 120 volt non-GFCI receptacles in dedicated spaces in garages and unfinished basements. If the location of the sump pump *receptacle *requires GFCI protection then you must have GFCI protection.

Subsequently, one may also ask, does a sump pump need a dedicated circuit?

The power supply to a sump pump should not only have a dedicated outlet, but should also be a Ground Fault Circuit Interrupter. The sump pump needs its own circuit breaker to prevent tripping of the breaker and the Ground Fault Circuit Interrupter is essential in preventing electrical shock.

Additionally, do finished basements need GFCI? If it's officially considered "habitable space", then it's a finished basement and GFCI is not required.

Also, why does my sump pump keep tripping the GFCI?

The GFCI is tripping because the pump has a leak from the wet side to the dry side. Moisture is present in the motor, and causing current from the motor windings into the case. This current, instead of flowing through the neutral, now flows either through the ground wire, or worse, through the water and/or plumbing.

Does a sump pump need a dedicated circuit in Ontario?
