Product FAQs
5 answersCan I install the QPHGFEP2020 in any Eaton panelboard?
No. This specific plug-on breaker is designed exclusively for Eaton Pow-R-Line 1a and Pow-R-Line 2a panelboards. If you are working with a panel that requires bolt-on connections, you will need the QBGFEP equivalent instead.
What is the difference between this GFEP breaker and a standard GFCI?
The QPHGFEP2020 is a Ground Fault Equipment Protector (GFEP) with a 30mA trip threshold, designed to protect machinery and heat tracing cables from low-level faults. Standard GFCI breakers have a 5mA threshold and are intended for personnel protection.
How do I connect the neutral on the QPHGFEP2020?
This breaker is equipped with a pigtail neutral wire. You must route and terminate this pigtail directly to the panelboard neutral bar for the ground fault protection circuitry to function correctly.
Is the QPHGFEP2020 interchangeable with QBGFEP or QCGFEP breakers?
No. While they offer the same 30mA equipment protection, the mounting styles differ. The QPHGFEP is a plug-on breaker, the QBGFEP is bolt-on, and the QCGFEP is cable-in/cable-out or panel mount. You must match the mounting style to your specific panelboard chassis.
Does upgrading to a GFEP breaker require more panel space?
No. The QPHGFEP2020 shares the same physical footprint as a standard two-pole QPH breaker. It will fit in the same space, provided there is adequate room to land the pigtail neutral on the neutral bar.
