Product FAQs
6 answersWhat is the ground fault trip sensitivity of the QBGFEP1020W1?
This Ground Fault Equipment Protection (GFEP) breaker features a 30mA trip sensitivity. It is specifically calibrated to protect equipment, such as heat trace cables and industrial machinery, from sustained ground faults rather than providing personnel life safety.
Can I use this 30mA GFEP breaker to protect standard bathroom or kitchen receptacles?
No. Standard bathroom, kitchen, and pool receptacles require a Class A Ground Fault Circuit Interrupter (GFCI) with a 5mA trip threshold to protect personnel from electric shock. This 30mA GFEP breaker is strictly rated for equipment protection.
What does the "W1" suffix indicate on this Eaton circuit breaker?
The "W1" suffix indicates that the breaker includes a factory-installed bell alarm. The bell alarm contacts change state only when the breaker trips, allowing panel builders and electricians to wire a remote indicator or monitoring system.
Which panelboards accept the QBGFEP1020W1 breaker?
This bolt-on miniature breaker is designed for direct installation into Eaton Pow-R-Line panelboards. It will also mount into legacy Cutler-Hammer and Westinghouse panelboards that utilize BAB or QB type bolt-on branch breakers.
How is the ground fault protection powered on this unit?
The breaker utilizes a factory-attached pigtail neutral wire. During installation, this coiled white wire must be routed and secured to the panelboard neutral bus bar to properly power and reference the internal ground fault sensing circuitry.
Is the Eaton QBGFEP1020W1 a direct replacement for older Cutler-Hammer versions?
Yes. Following Eaton's acquisition of Cutler-Hammer, the distribution equipment product lines were merged. The current Eaton QBGFEP1020W1 is the exact, manufacturer-approved replacement for legacy Cutler-Hammer and Westinghouse breakers bearing the same catalog number.
