Product FAQs

6 answers
Which panelboards are compatible with the QBGF1020 circuit breaker?

This BAB-frame breaker is designed for bolt-on installation in Eaton Pow-R-Line and legacy Cutler-Hammer Quicklag panelboards.

How is the pigtail neutral connected on this breaker?

The QBGF1020 includes a coiled white pigtail wire that must be landed directly on the panel's neutral bus bar. This connection is required to power the internal circuitry that monitors for ground faults.

What level of ground fault protection does this breaker provide?

It provides Class A ground fault protection with a 5mA trip threshold. This level of sensitivity is required by the National Electrical Code (NEC) for personnel protection in locations where water or moisture may be present.

Can the QBGF1020 be used for equipment ground fault protection (GFEP)?

No. This breaker trips at 5mA for personnel safety. For equipment protection, which typically requires a 30mA trip threshold, you need a breaker from the QBGFEP series.

What is the difference between the QBGF1020 and the QBHGF1020?

The main difference is the short-circuit interrupting rating. The QBGF1020 is rated for 10 kAIC at 120V, while the QBHGF1020 provides a higher 22 kAIC rating. Both are bolt-on GFCI breakers with identical physical dimensions.

Are Eaton and Cutler-Hammer QBGF1020 breakers interchangeable?

Yes. Eaton acquired Cutler-Hammer, so you may see the QBGF1020 branded under either name. Both versions share the exact same engineering, fit, and UL listings.

    Pleasantly Surprised!

    Items came new, in factory boxes. Well packaged, not damaged.

    Someone cared when the order was picked and packaged that says a lot.

    Thanks

    Right stuff, right price

    Got an Eaton "BR" type 2 pole 30A bolt-in GFI breaker. OEM packaging and paperwork inside. Would buy from them again.
