Product FAQs
6 answersCan I install the QO235GFI in a Square D Homeline panel?
No. The QO235GFI is designed exclusively for Square D QO load centers, NQ panelboards, and NQOD panelboards. Homeline panels require Homeline (HOM) series breakers.
How is the neutral connection made on the QO235GFI?
This breaker features a pigtail neutral connection. The coiled white wire must be routed and connected directly to the neutral bus bar in the panel to power the GFCI circuitry.
Can the QO235GFI be used for straight 240V loads that do not have a neutral wire?
Yes. A 2-pole GFCI breaker can protect straight 240V loads, such as certain pumps or heaters. The breaker's white pigtail must still be connected to the panel's neutral bar, but the load neutral terminal on the breaker can be left empty.
What level of ground fault protection does the QO235GFI provide?
This breaker provides Class A ground fault protection, which is designed to trip when a ground fault of 4 to 6 milliamperes is detected, protecting personnel from electrical shock.
What does the LIG trip function mean on the QO235GFI?
LIG stands for Long-Time, Instantaneous, and Ground-Fault. This indicates the breaker provides thermal protection against standard overloads (Long-Time), magnetic protection against short circuits (Instantaneous), and Class A protection against ground faults.
Does the QO235GFI feature a tripped circuit indicator?
Yes. It includes the Square D Visi-Trip indicator. When the breaker trips, the handle snaps to a midpoint position and a highly visible red indicator appears, allowing for quick identification of the faulted circuit.
