Product FAQs
6 answersWhat panelboards are compatible with the QBHGF1020?
This breaker is designed for use in Eaton Pow-R-Line panelboards that accept bolt-on BAB or Quicklag style circuit breakers.
What is the difference between the QBGF1020 and the QBHGF1020?
The 'H' in QBHGF indicates a higher interrupting rating. The QBHGF1020 is rated for 22kAIC at 120V, whereas the standard QBGF1020 is rated for 10kAIC.
What level of ground fault protection does the QBHGF1020 provide?
It is a Class A Ground Fault Circuit Interrupter (GFCI), meaning it features a 5mA trip sensitivity designed specifically for personnel protection against electrical shock.
Does this breaker require a neutral connection to function?
Yes, it features a pigtail neutral wire that must be securely connected to the panelboard's neutral bar for the ground fault detection circuitry to operate correctly.
Can the QBHGF1020 be backfed for use as a main breaker?
No. Eaton specifies that their circuit breakers with ground fault capabilities are not suitable for backfeed or reverse feed applications.
How do I verify the ground fault protection is working after installation?
Once installed and energized, press the built-in test button on the face of the breaker. The breaker should trip immediately, confirming the GFCI circuitry is functioning properly.
