Product FAQs
8 answersCan I install the QO250GF in a Homeline load center?
No. QO series breakers are not interchangeable with Homeline panels. This breaker is designed exclusively for Square D QO load centers and NQ panelboards.
What is the difference between the QO250GF and QO250GFI catalog numbers?
There is no functional difference. QO250GF is the base catalog number, while QO250GFI is often used by the manufacturer and distributors to denote the exact same ground fault circuit interrupter. Both refer to the same 50A 2-pole GFCI breaker.
How do I wire the pigtail neutral on the QO250GF?
The coiled white pigtail wire must be connected directly to the neutral bus bar in your QO load center or NQ panelboard. This connection is required to power the internal ground fault circuitry, even if your 240V load does not use a neutral wire.
Can this 2-pole GFCI breaker be used for a straight 240V load like a hot tub that lacks a neutral wire?
Yes. The QO250GF can protect a strictly 240V load. You will connect the two hot wires to the breaker load terminals. The breaker pigtail must still connect to the panel neutral bus, but the load neutral terminal on the breaker remains empty.
What level of ground fault protection does the QO250GF provide?
This breaker provides Class A ground fault protection. It is designed to trip when it detects a ground fault current of 6 mA or higher, which provides personnel protection for wet or damp locations.
Does the QO250GF require a plug-on neutral panel?
No. This specific breaker features a pigtail neutral connection, meaning it works in standard QO load centers and NQ panelboards. It does not require a specialized plug-on neutral panel chassis.
What do the LIG trip functions mean on this breaker?
LIG stands for Long-Time, Instantaneous, and Ground Fault. Long-Time protects against sustained overloads, Instantaneous trips during severe short circuits, and Ground Fault protects against leakage current to ground.
Will this breaker fit in an older Square D QO panel?
Yes, the QO250GF uses the standard QO plug-on mounting interface. It is backward compatible with legacy QO load centers as long as the panel is rated to accept a 50A 2-pole breaker.
