Product FAQs
6 answersCan I install this 25A GFCI breaker in a Square D Homeline panel?
No. Square D QO breakers are not interchangeable with Homeline breakers. This unit is designed exclusively for QO load centers and NQ panelboards.
Does this breaker require a neutral connection?
Yes. It features a pigtail neutral wire that must be connected directly to the neutral bus bar in your panel to ensure proper ground fault detection.
Can I use this 1-pole breaker for a 240V circuit?
No. This is a single-pole breaker rated for 120VAC applications only. A 2-pole breaker is required for 240V circuits.
How can I tell if this breaker has tripped?
This unit features the Square D Visi-Trip indicator. When the breaker trips, the handle moves to a center position and a highly visible red indicator appears, making it easy to identify the tripped circuit in your panel.
What level of ground fault protection does the QO125GFI provide?
This breaker provides Class A ground fault protection. It is designed to trip when a ground fault of 5mA is detected, offering personnel protection against electrical shock.
What are the alternate catalog numbers for the QO125GFI?
This breaker is also commonly referenced under alternate part numbers QO125GF, QO125GFIC, and QO125GFCI.
