Product FAQs
6 answersWhat panelboards are compatible with the QOB115VHGFI circuit breaker?
This bolt-on breaker is designed exclusively for use in Square D NQ and NQOD panelboards. It will not fit standard QO load centers, which require plug-on breakers.
What does the VH designation in the QOB115VHGFI catalog number indicate?
The VH designates a higher interrupting rating of 22kAIC at 120VAC. Standard QOB breakers without the VH suffix typically feature a standard 10kAIC rating.
What class of ground fault protection does the QOB115VHGFI provide?
This breaker provides Class A ground fault protection. It is designed to trip when a ground fault current of 6mA or higher is detected, providing personnel protection against electrical shock.
How is the neutral connection made for this GFCI breaker?
The QOB115VHGFI features a pigtail neutral wire. This wire must be routed and connected directly to the neutral bus bar in the panelboard to ensure the ground fault detection circuitry functions correctly.
What is the recommended tightening torque for the load terminals?
The pressure plate terminals on this breaker should be torqued to 40.7 lb-in (4.6 N.m) to ensure a secure connection when using 14 to 8 AWG copper or 12 to 8 AWG aluminum conductors.
Is there a plug-on equivalent to the QOB115VHGFI?
Yes. If your application requires a plug-on connection for a standard QO load center rather than a bolt-on panelboard, the equivalent part number is QO115VHGFI.
