2008 NEC Eliminates GFCI Exemption This only applies to cord-and-plug connections of a septic or sump pump, because the code applies to receptacles, not the appliances that might be connected to them.

Should a sump pump be on a 20 amp breaker?

Re: Sump Pump Wiring ??? If it’s a 20 amp circuit, #12 should be used as wiring to a 20 amp breaker. It need not have 20 amp receptacles, however. If it’s a 15 amp circuit, either #12 or #14 could be used, as a lower amp circuit can always safely use wire rated for a higher amp circuit.

Can a sump pump trip a GFCI circuit?

Most sump pumps will not trip a GFCI circuit but it can if there are electrical problems with the pump or power surges.

What should I use to avoid tripping my GFCI breaker?

For best reliability—and to avoid tripping the subpanel circuit breaker when both pumps are active—the backup pump should also connect to a dedicated GFCI-protected branch circuit (typically 120 VAC, 15 A or 20 A).

What causes nuisance tripping of basement sewage pump?

Sewage basin in residential-home basement (Zoeller Company). After 10 years of reliable operation, a California homeowner experienced nuisance (ghost) tripping of a basement Ground-Fault Circuit-Interrupter (“GFCI”) whenever activating the sewage pump.

What to do when a sump pump is tripping a breaker?

It is important that your sump pump has its dedicated outlet to plug into. If other devices are plugged into an outlet, then there is a much greater chance of using too much power. Also, it may be the other device that is causing the entire problem and not your sump pump. It is important to use only a GFCI outlet for a sump pump.

What causes a GFCI nuisance tripping of sewage?

This breach sets up a hazardous condition wherein the 120V hot conductor is in direct or intermittent contact with accumulated wastewater. The wastewater, which is composed of contaminating organic material, salts and other chemicals, conducts electricity to the ground wire via the GFCI and back to the circuit-breaker panel.
