Product FAQs
6 answersWhat is the ground fault trip sensitivity of the Eaton QBGFT2020?
This Class A GFCI breaker features a 5mA trip sensitivity threshold, designed specifically for personnel protection against electric shock.
What does the LIG trip function code mean for this breaker?
LIG indicates the three specific trip protections this breaker provides: Long-Time for sustained thermal overloads, Instantaneous for magnetic short-circuit protection, and Ground Fault for 5mA personnel protection.
Is the QBGFT2020 a replacement for the older QBGF2020?
Yes, it is the direct replacement for the legacy QBGF2020. The newer QBGFT model includes an automated self-test feature to ensure the internal ground fault circuitry remains compliant with current UL safety standards.
Can I install this bolt-on breaker in a standard residential load center?
No. The QBGFT2020 is a BAB-frame bolt-on circuit breaker designed for commercial Eaton Pow-R-Line 1a and 2a panelboards. It is not compatible with load centers that require plug-on type breakers like the standard BR or CH series.
How does the neutral connection work on this GFCI breaker?
The breaker is equipped with a factory-installed pigtail neutral wire. During installation, this pigtail must be securely terminated at the panelboard's neutral assembly for the ground fault sensing circuitry to operate correctly.
Does the QBGFT2020 provide combination arc fault (AFCI) protection?
No, this model is exclusively a Ground Fault Circuit Interrupter (GFCI) with standard thermal-magnetic overload and short-circuit protection. It does not provide AFCI protection.
