Product FAQs
6 answersWhat panelboards are compatible with the QB1020GF?
This bolt-on breaker is designed for Eaton Pow-R-Line commercial panelboards, specifically the PRL1X series that accept Quicklag branch breakers. It will not fit standard residential plug-on load centers.
What is the ground fault trip threshold for this breaker?
The QB1020GF features a 5mA trip sensitivity. This classifies it as a Class A GFCI device intended to provide personnel protection in wet or damp locations.
What is the difference between the QB1020GF and the QB1020EP?
The QB1020GF provides Class A personnel protection with a 5mA trip threshold. The QB1020EP is designed specifically for equipment protection and uses a higher 30mA trip threshold to prevent nuisance tripping on machinery.
How is the ground fault circuitry wired during installation?
The breaker includes a coiled pigtail neutral wire that must be connected directly to the neutral bus bar in your panelboard. The load neutral also connects directly to the breaker terminal to complete the GFCI monitoring circuit.
Is the QB1020GF a direct replacement for the QBGF1020?
Yes. Eaton occasionally lists this 20A GFCI model under the legacy catalog number QBGF1020. Both numbers refer to the exact same bolt-on breaker footprint and electrical specifications.
Can this breaker be used in continuous load applications?
Standard thermal magnetic breakers, including the QB1020GF, are rated for 80 percent continuous load under the National Electrical Code. You should not exceed 16 amps for connected continuous loads that operate for three hours or more.
