Eaton QBHGFT2020 – Frequently Asked Questions

1) Will an Eaton QBHGFT2020 GFCI breaker fit my panel, or do I need to check the bus type first?
Check the bus first. The QBHGFT2020 is an Eaton QB-type bolt-on breaker, and bolt-on breakers mount to a panelboard bus drilled and tapped for that specific line. It will not seat on a plug-in load center bus, and it is not interchangeable with another manufacturer's bolt-on. The breaker body measures 2.75 x 4.5 x 2 inches, so confirm you have the gutter depth and two-pole space for it. If your panel takes plug-on breakers, you want a plug-in GFCI type instead, not this one.
2) Can I use a two-pole 20A GFCI breaker for a 240V hot tub or spa disconnect?
A two-pole 20A GFCI breaker is the right configuration for a 240V load that needs ground-fault protection, and the QBHGFT2020 is rated 20A at 120/240V with GFCI protection built into the breaker. The load has to actually be a 20A circuit, though. Most spa packs call for 50A or 60A, so size the breaker to the equipment nameplate and the feeder, not to what fits the space. At 20A this is more commonly used for a 240V pump, small heater, or a 120/240V multiwire branch circuit.
3) Is the Eaton QBHGF 20A breaker rated for an air conditioner or heat pump circuit?
Yes, it carries an HACR rating, which is what an inspector looks for on a breaker feeding heating, air conditioning, or refrigeration equipment. Combined with the GFCI function, that makes the QBHGFT2020 usable where an HVAC branch circuit also needs ground-fault protection. Match the 20A rating against the maximum overcurrent protection figure on the condenser or air handler nameplate, since HVAC nameplates frequently specify a maximum breaker size that is larger than the minimum circuit ampacity.
4) I am replacing a standard two-pole 20A Eaton QB breaker with this GFCI version. Does anything else have to change?
The circuit gets a neutral requirement it may not have had. A GFCI breaker needs the circuit's neutral landed on the breaker's own neutral terminal, not on the panel neutral bar, plus the breaker's pigtail run to the neutral bar. A straight 240V two-pole circuit pulled with two hots and a ground has no neutral to land, so it cannot be converted without pulling a new conductor. Electrically the QBHGFT2020 matches a standard two-pole 20A at 120/240V, and it is 2.75 inches wide, so the panel space is the same.
5) What is the difference between putting in a GFCI breaker like this and using GFCI receptacles on the circuit?
A GFCI breaker protects the entire circuit from the panel out, including the wiring in the walls and any hardwired equipment, and it lets you put ground-fault protection on a 240V two-pole load where no receptacle option exists. GFCI receptacles only protect from their own terminals downstream, and they cannot protect a hardwired motor, heater, or HVAC unit. The QBHGFT2020 is the breaker-side approach for a 120/240V two-pole circuit. The tradeoff is resetting: a trip sends someone to the panel rather than to the device, so for a single 120V receptacle location in a finished space the receptacle is usually the easier call.
6) Does this Eaton GFCI breaker carry a UL listing I can show an inspector?
It is UL 489 certified, which is the standard for molded-case circuit breakers used as branch-circuit overcurrent protection, and it is HACR rated for heating, air conditioning, and refrigeration circuits. UL 489 is the listing an AHJ expects on a breaker installed in a panelboard, so specifying the QBHGFT2020 will not create a plan-review problem on that point.
7) Will a two-pole GFCI breaker work on a multiwire branch circuit feeding two 120V circuits?
That is one of the standard uses for it. Because the QB two-pole GFCI is rated 120/240V and handles the neutral through the breaker, it senses both hot legs and the shared neutral together, which is what a multiwire branch circuit needs for the ground-fault sensing to work correctly. Each leg is protected at 20A. Two separate single-pole GFCI breakers cannot be used on a shared neutral, because each one would read the other's return current as a fault and trip.
8) Does a GFCI breaker also satisfy an AFCI requirement?
No. Ground-fault and arc-fault are two different protections. The QBHGFT2020 is a ground fault circuit breaker, type QBHGF, and it detects current leaking to ground, which is a shock and fire hazard from a ground fault. It does not detect the arcing signature that an AFCI looks for. Where the NEC calls for arc-fault protection on a circuit, you need an AFCI or a dual-function breaker instead. Where the requirement is ground-fault only, this covers it.
9) What exact part number do I order for the Eaton two-pole 20A QB GFCI breaker?
The manufacturer part number is QBHGFT2020, an Eaton QB Series two-pole ground fault breaker rated 20A at 120/240V with a 22 kAIC interrupt rating. Reading the designation: QB is the bolt-on breaker line, HGF marks it as the ground fault version, and the trailing 2020 is the 20A rating on each of the two poles. There is one configuration, so there is no finish, trim, or terminal option to specify with the order.
10) How much panel space does the Eaton QBHGFT2020 take up?
Two full-size spaces. The breaker is 2.75 inches wide overall, covering two poles on the bus, with a 4.5 inch length/depth and a 2 inch height. The depth figure is the one that catches people on a shallow panel or a tight can, since GFCI breakers are deeper than a standard thermal-magnetic breaker and the neutral pigtail needs bending room in the gutter. Measure from the bus to the inside of the cover before you commit on a panel that is already full of wire.
11) Can I standardize on one GFCI breaker across a portfolio of buildings with mixed panels?
Only across panels that take the Eaton QB bolt-on line. The QBHGFT2020 is type QBHGF, and breaker type is what determines whether it seats, so a property with a mix of Eaton QB panelboards and other manufacturers' panels cannot run on a single breaker part number. Where the QB panels are consistent, this one part number covers 20A two-pole 120/240V GFCI needs, including HVAC circuits thanks to the HACR rating, which is usually enough to keep a single line item on the truck stock list.
