Product FAQs
6 answersWhat panelboards are compatible with the QOB215GFI?
The QOB215GFI is a bolt-on circuit breaker designed exclusively for use in Square D NQ and NQOD panelboards. It cannot be used in standard QO load centers, which require plug-on breakers.
Is there a plug-on equivalent for the QOB215GFI?
Yes. If you are installing a breaker in a standard Square D QO load center rather than a bolt-on panelboard, the plug-on equivalent is the QO215GFI.
How is the neutral connection made on the QOB215GFI?
This breaker features a pigtail neutral connection. The coiled white pigtail wire must be connected directly to the panel's neutral bus bar for the ground fault protection to function correctly.
What level of ground fault protection does the QOB215GFI provide?
It provides Class A ground fault protection, which is designed for personnel safety. It detects ground faults and trips when the leakage current reaches the 4 to 6 mA range, meeting NEC requirements for wet or damp locations.
Can I use the QOB215GFI for equipment protection?
No, the QOB215GFI is a Class A GFCI designed for personnel protection. For equipment protection requiring a 30mA trip threshold to prevent nuisance tripping on heat trace or industrial equipment, you need an Equipment Protection Device (EPD) breaker.
What does the LIG trip function code mean on this breaker?
LIG stands for Long-Time, Instantaneous, and Ground-Fault. This indicates the breaker provides thermal protection against overloads, magnetic protection against short circuits, and integrated protection against ground faults.
