Why Eaton?

Eaton engineers the QBGF Quicklag Ground Fault Circuit Breaker for dependable, code-compliant performance in demanding electrical environments. With UL 489 listing, HACR certification, and a rugged bolt-on mounting design, this breaker protects personnel and equipment through sensitive 5mA ground fault detection across a wide range of amperage, pole, and interrupting rating combinations. Electrical professionals can specify Eaton QBGF breakers with confidence for new construction and panel upgrades, relying on 10 kAIC and 22 kAIC interrupting ratings to match the fault-current demands of residential and light commercial installations. The bolt-on design resists loosening from vibration over time, helping panelboards and load centers maintain secure connections through years of service in both new construction and retrofit panel upgrades where sensitive ground fault protection is required by code.

Eaton QB1020GF – Frequently Asked Questions

1) Will an Eaton QBGF Quicklag GFCI breaker fit my panel, or do I need a plug-on breaker?
The QBGF is a bolt-on breaker. It fastens to the panelboard bus with a screw instead of clipping on, so it only goes into a panelboard or load center that is built to take bolt-on breakers. If your panel uses plug-on (snap-in) breakers, a QBGF will not seat in it and you want a plug-on GFCI breaker instead. Bolt-on bus is what most commercial and industrial panelboards use, and it is the reason this style holds its connection where there is vibration.
2) Should I order the Eaton QBGF in 10 kAIC or 22 kAIC?
Order to the available fault current at the panel where it lands. The QBGF comes in 10 kAIC and 22 kAIC interrupting ratings at 120/240 V. 10 kAIC is the standard residential load center rating; 22 kAIC is for higher fault-current commercial and light-industrial panels, and it is what a panel schedule usually calls out when the service is large or the panel sits close to the transformer. A breaker's interrupting rating has to be at least the available fault current at its terminals, so if the drawing states a minimum AIC, that number decides the choice, not the amperage.
3) Do I need a 1-pole or 2-pole QBGF ground fault breaker?
Pole count follows the load. Single-pole QBGF breakers serve 120 V branch circuits: receptacles, lighting, general-purpose outlets. Two-pole serves 240 V or 120/240 V loads, which is what a water heater, a condenser, or a large appliance needs. If the equipment nameplate says 240 V, or the circuit runs two hots, it is a 2-pole. Both pole options carry the same 5 mA ground fault trip.
4) Is the Eaton QBGF a people-protection GFCI or an equipment ground fault breaker?
People protection. The QBGF trips at 5 mA, which is the sensitivity used for personnel protection on bathroom, kitchen, garage, and outdoor branch circuits. Equipment ground fault protection devices are a different animal and trip much higher, around 30 mA, because they exist to protect the equipment and the wiring, not a person in contact with it. If an inspector is asking for GFCI protection of personnel on a branch circuit, 5 mA is the number they are looking for.
5) Should I put in a GFCI breaker like the Eaton QBGF or just a GFCI receptacle?
A GFCI breaker protects the whole branch circuit from the panel outward, so every outlet, light, and hardwired piece of equipment downstream is covered, including the cable in the wall. A GFCI receptacle only protects itself and whatever is wired to its load terminals. Go with the QBGF breaker when the circuit feeds hardwired equipment with no place to put a receptacle, when the outlets are outdoors or otherwise hard to reach for testing, or when you want one device to cover several boxes. Its 5 mA trip is the same personnel sensitivity a GFCI receptacle uses.
6) Can Eaton QBGF breakers protect outdoor and wet location circuits?
That is what the 5 mA sensitivity is there for. The QBGF is intended for branch circuits in wet and damp locations, so outdoor receptacles, garages, bathrooms, and kitchen circuits are all in scope. The breaker itself lives inside the panelboard, in the dry, and protects the circuit that runs out to the wet location, so the enclosure rating you need at the far end is a separate item from this breaker.
7) Is the Eaton QBGF UL listed for use as a branch circuit breaker on a commercial panel schedule?
The QBGF Quicklag is UL 489 Listed, which is the standard for molded case circuit breakers used as branch circuit and feeder overcurrent protection, and it is HACR rated on top of that. If a spec or panel schedule calls for a UL 489 listed branch breaker with 5 mA ground fault protection, the QBGF meets that description. Pair the UL 489 listing with the correct interrupting rating for the panel, since the listing and the AIC are separate requirements.
8) I'm upgrading GFCI protection across a building's panels. Can I standardize on the Eaton QBGF Quicklag?
For any panel that takes bolt-on breakers, yes. The QBGF range runs 15A through 50A in 1-pole and 2-pole, in both 10 kAIC and 22 kAIC, and every one of them trips at the same 5 mA, so one family covers the 120 V receptacle circuits, the 240 V appliance circuits, and the HVAC circuits across a mixed building. The limits worth checking before you commit the whole property: panels that take plug-on breakers will not accept these, nothing above 50A is in the range, and lower fault-current panels and higher ones need their own AIC rating.
