Product FAQs
6 answersWhat is the difference between this GFEP breaker and a standard GFCI breaker?
The Eaton QB1030EP is a Ground Fault Equipment Protector (GFEP) with a 30mA trip sensitivity, designed specifically to protect machinery such as heat tracing cables. Standard GFCI breakers (Class A) have a much lower 5mA trip threshold intended to protect personnel from shock.
Which panelboards are compatible with the QB1030EP?
This bolt-on miniature circuit breaker is engineered for installation in commercial Eaton Pow-R-Line panelboards that accept Quicklag QB type breakers. It requires a busbar designed specifically for bolted connections.
How is the neutral connected on this ground fault breaker?
This breaker utilizes a pigtail neutral connection. The attached white pigtail wire must be wired directly to the neutral bar of your panelboard to enable the ground fault monitoring circuitry.
Does the QB1030EP replace older Cutler-Hammer part numbers?
Yes, the QB1030EP serves as the direct replacement for the legacy Cutler-Hammer QBGFEP1030 equipment protection breaker.
Is this 30mA GFEP breaker suitable for wet location personnel protection?
No. Because this breaker features a 30mA ground fault threshold, it is not rated for personnel protection (Class A 5mA) required for bathrooms, kitchens, or general residential wet locations. It is intended strictly for safeguarding equipment from line-to-ground faults.
What size wire is accepted by the terminals on this 30A equipment protector?
The box lugs on the QB1030EP accommodate copper or aluminum wiring ranging from 14 AWG to 4 AWG. Always verify local codes for correct wire sizing on 30A branch circuits.
