Product FAQs
8 answersWhat does the VH stand for in the QO120VHGFI catalog number?
The VH designates a higher interrupting rating of 22kA at 120VAC, compared to the standard 10kA rating found on the base QO120GFI model. This makes it suitable for commercial or industrial applications requiring higher fault current defense.
Can I install the QO120VHGFI in a Square D Homeline panel?
No. QO series breakers have a 3/4-inch per pole footprint and are only compatible with QO load centers and NQ panelboards. Homeline panels require 1-inch per pole Homeline breakers and are not interchangeable.
Does this breaker require a plug-on neutral panel?
No. The QO120VHGFI features a pigtail neutral wire that must be manually connected to the neutral bus bar in your panel. It is designed for standard QO load centers and NQ panelboards that do not have plug-on neutral capabilities.
What level of ground fault protection does the QO120VHGFI provide?
This breaker provides Class A ground fault protection, meaning it is designed to trip when it detects a ground fault current between 4 mA and 6 mA. This protects personnel from electrical shock in wet or damp locations like bathrooms, kitchens, and outdoor circuits.
What is the difference between the QO120VHGFI and the QO120GFI?
Both are 20A, 1-pole GFCI breakers for QO panels, but they have different interrupting ratings. The QO120VHGFI is rated for 22kA, while the standard QO120GFI is rated for 10kA.
Can this GFCI breaker be installed in a commercial NQ panelboard?
Yes. The QO120VHGFI is fully compatible with Square D NQ panelboards as well as standard residential QO load centers, making it suitable for both commercial and residential 120VAC applications requiring 22kA interrupting capacity.
Does this breaker include arc fault (AFCI) protection?
No. The QO120VHGFI is strictly a Ground Fault Circuit Interrupter (GFCI) and provides thermal-magnetic overload and short circuit protection. If your circuit requires both AFCI and GFCI protection to meet NEC requirements, you will need a Dual Function (DF) breaker instead.
How do I visually identify if the QO120VHGFI has tripped?
It features the Square D Visi-Trip indicator. When the breaker trips due to an overload, short circuit, or ground fault, the handle moves to the center position and a red flag appears in a small window on the face of the breaker for quick troubleshooting.
