Product FAQs
7 answersCan I install the QOB230GFI in a standard QO load center?
No. The QOB230GFI is a bolt-on breaker specifically designed for NQ and NQOD panelboards. If you need this breaker for a standard plug-on QO load center, you must use the QO230GFI.
What class of ground fault protection does the QOB230GFI provide?
This breaker provides Class A ground fault protection. It is designed to trip when a ground fault of 4 to 6 milliamps is detected, ensuring safety for personnel against electrical shock.
How do I wire the neutral connection on the QOB230GFI?
This breaker utilizes a pigtail neutral. The white pigtail wire must be connected directly to the panelboard neutral bar, and the neutral from the load circuit must be terminated at the breaker load neutral lug for the ground fault sensing to function correctly.
What is the plug-on equivalent for the QOB230GFI?
The direct plug-on equivalent is the QO230GFI. It shares the same electrical and trip characteristics but features a snap-in mounting style for standard QO residential and commercial load centers.
How much panel space does this breaker require?
Because it uses the Square D QO format, the 2-pole QOB230GFI requires two standard 3/4 inch spaces in an NQ or NQOD panelboard.
Can I use this 2-pole GFCI on a multi-wire branch circuit?
Yes. A 2-pole GFCI breaker like the QOB230GFI can protect a 120/240VAC multi-wire branch circuit with a shared neutral, provided the shared load neutral is properly connected to the neutral terminal on the breaker.
What is the difference between the QOB230GFI and the QOB230EPD?
The QOB230GFI offers Class A personnel protection with a 5 milliamp trip threshold. The QOB230EPD is an Equipment Protection Device (EPD) that trips at a higher 30 milliamp threshold to protect equipment from damage rather than providing life-safety shock protection.
