Description
Part of the QO series, the Square D QO220GFI provides essential 20A ground-fault protection for electrical systems. This two-pole breaker is engineered to detect low-level ground faults and interrupt power to prevent electrical shock. It installs into QO load centers and NQ panelboards using a plug-on mounting style and included pigtail neutral. Featuring a 10 kAIC interrupt rating, it combines thermal-magnetic trip technology with 6mA Class A GFCI safety and a Visi-Trip window.Specifications

Product FAQs
7 answersWhat level of ground fault protection does the QO220GFI provide?
It provides Class A ground fault protection. The breaker is calibrated to trip when a ground fault exceeds 4 to 6 milliamperes (mA), providing standard personnel protection against electrical shock.
Does this breaker require a load center with a plug-on neutral bus?
No. The QO220GFI uses a pigtail neutral. The coiled white wire connects directly to the panel's neutral bus bar, making it suitable for both older standard QO load centers and newer panels.
How do I identify if this breaker has tripped during a fault?
It features the Square D Visi-Trip indicator. Upon tripping, the handle rests in a center position and a bright red flag appears in the indicator window, allowing quick visual identification in a crowded panel.
Is this 2-pole GFCI breaker suitable for a multi-wire branch circuit?
Yes. A 2-pole GFCI can protect a 120/240V multi-wire branch circuit (shared neutral) or a straight 240V load. For a shared neutral application, the circuit neutral must land directly on the breaker's neutral load terminal, while the pigtail connects to the panel neutral bar.
Can I install this QO circuit breaker in a Square D Homeline panel?
No. QO series breakers feature a 3/4-inch per pole format and specific mounting clips. They are mechanically incompatible with 1-inch format Homeline load centers.
How much panel space does this ground fault breaker require?
As a 2-pole QO series breaker, it requires two standard 3/4-inch spaces in a compatible QO load center or NQ panelboard.
What is the difference between catalog numbers QO220GFI, QO220GFIC, and QO220GFICP?
The circuit breaker itself is identical across these numbers. Suffixes like C or CP simply designate retail commercial clamshell packaging instead of standard bulk packaging.
