Eaton Bolt-On Dual-Function AF/GF Circuit Breaker, Single-Pole

The Eaton Bolt-On Dual-Function AF/GF Circuit Breaker is a single-pole breaker that combines arc-fault (AF) and ground-fault (GF) protection in one device for enhanced circuit safety. Featuring a bolt-on connection for a secure, vibration-resistant mount to the panel bus, this breaker is built for reliable performance in residential and light commercial load centers. It carries a voltage rating of 10 and is engineered to meet the demands of modern branch-circuit protection where combined arc-fault and ground-fault detection is required.

Key Features

  • Dual-Function Protection: Combines arc-fault (AF) and ground-fault (GF) circuit interruption in a single device for broader protection against dangerous fault conditions.
  • Bolt-On Connection: Bolt-on mounting style secures the breaker firmly to the panel bus bar, reducing the risk of loosening from vibration over time.
  • Single-Pole Configuration: Single-pole (1P) design suited for standard 120V branch circuits requiring combined arc-fault and ground-fault coverage.
  • Voltage Rating: Rated at 10, supporting compatibility with Eaton-compatible load centers and panelboards.
  • Panel Compatibility: Designed as a bolt-on replacement/addition breaker for compatible Eaton panelboards and load centers.

Technical Specifications

  • Number of poles: Single-pole
  • Voltage Rating: 10
  • Department: Electrical

Typical Applications

  • Residential Load Center and Panelboard Circuit Protection
  • Branch Circuits Requiring Combined Arc-Fault and Ground-Fault Protection
  • Panel Upgrades and Breaker Replacements

Eaton QB1020AFGF – Frequently Asked Questions

1) What amperages does the Eaton QB bolt-on dual-function AF/GF breaker come in?
The Eaton QB single-pole dual-function AF/GF breaker is offered in two ratings: 15 amp, model QB1015AFGF, and 20 amp, model QB1020AFGF. Those are the two standard 120V branch-circuit sizes, 15A for general lighting and receptacle circuits and 20A for kitchen, laundry, and other small-appliance circuits. Order by the circuit the conductor is sized for, not by what fits the space in the panel.
2) Will an Eaton QB bolt-on breaker fit my panel, or do I need a plug-on type?
The QB dual-function breaker is a bolt-on device, so it only goes into a panelboard or load center with a bolt-on bus. It fastens to the bus with a screw rather than clipping on, which is why it holds up in equipment that sees vibration. If the interior in your panel takes plug-on breakers that snap onto bus stabs, this one will not seat, and a bolt-on breaker cannot be adapted to a plug-on bus. Check what is already in the panel before ordering: bolt-on breakers have a visible mounting screw at the bus end.
3) Can I use a single-pole AF/GF breaker on a 240V circuit or a shared neutral?
No. The QB AF/GF breaker is single-pole, built for a 120V branch circuit with its own hot and its own neutral. A 240V load or a multiwire branch circuit sharing one neutral between two hots needs a two-pole dual-function breaker instead. Putting a single-pole dual-function device on a shared neutral will trip it, because the return current it sees will not match what left on its hot leg.
4) Can I swap a standard bolt-on breaker for an Eaton QB AF/GF breaker in the same panel slot?
Mechanically, yes, in a panel already built for bolt-on breakers, and the single-pole QB AF/GF occupies one pole the same as a standard single-pole. The wiring is what changes: you have to pull that circuit's neutral off the panel neutral bar and land it on the breaker, then run the breaker's pigtail to the bar. If the circuit shares its neutral with another circuit, the swap will not work until the neutrals are separated.
5) What is the difference between a dual-function AF/GF breaker and a plain AFCI breaker?
An AFCI breaker detects arcing faults only, the kind of damaged-cable or loose-termination arcing that starts fires. The Eaton QB dual-function breaker does that and adds ground-fault protection in the same device, so one breaker covers both. That matters where a circuit falls under both requirements at once, a kitchen or laundry circuit for example, because the alternative is an AFCI breaker plus GFCI receptacles at each point of use. On a panel rebuild it also saves a slot compared to stacking separate protection.
6) How do I wire a dual-function AF/GF breaker in an existing panel?
Wiring differs from a standard breaker, which is where most callbacks come from. The circuit hot lands on the breaker's load terminal, the circuit neutral lands on the breaker's neutral terminal, and the breaker's own white pigtail goes to the panel neutral bar. Both conductors of the branch circuit have to come off the neutral bar and onto the breaker, otherwise the ground-fault sensing has nothing to compare. The QB bolt-on breaker also gets torqued down to the bus with its mounting screw rather than pressed on.
7) Which Eaton AF/GF breaker do I order for a bedroom circuit versus a kitchen counter circuit?
A bedroom lighting and receptacle circuit on 14 AWG takes the 15 amp QB1015AFGF. Kitchen counter small-appliance circuits are run on 12 AWG and take the 20 amp QB1020AFGF. Both are single-pole dual-function devices, so the choice between them is purely the conductor size and the load the circuit was designed for. Never fit the 20 amp on a circuit wired with 14 AWG.
8) Are Eaton bolt-on AF/GF breakers suitable for commercial panelboards or only houses?
Both. The QB dual-function breaker is used in residential load centers and light commercial panelboards, and the bolt-on bus connection is a large part of why: it stays tight in equipment subject to vibration, which is common in commercial mechanical spaces. For a property manager standardizing across a building, the two ratings offered, 15 amp and 20 amp single-pole, cover ordinary 120V branch circuits in either setting.
