Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

The Square D HomeLine 20 Amp Arc Fault Single Pole Circuit Breaker is a purpose-built safety upgrade for indoor electrical panels. Designed for quick replacement in compatible HomeLine panels, this plug-in AFCI breaker adds essential protection to a single 120V circuit, helping reduce the risk of electrical fires caused by arcing faults while keeping your wiring compliant with modern safety standards.

  • Arc Fault Protection detects and interrupts dangerous arcing events on the protected circuit, providing an important layer of safety for living spaces, bedrooms, and home offices.
  • 20 Amp, 120V rating fits a wide range of general-purpose outlets and lighting circuits common in residential wiring.
  • Single Pole design protects one branch circuit, offering straightforward upgrade without reconfiguring your panel.
  • Plug-In Mounting enables fast, tool-free installation in compatible panels—minimizing downtime during upgrades or retrofits.
  • UL Listed & CSA Listed for proven safety and compliance across standard electrical installations.
  • HomeLine Series compatibility ensures a seamless fit with existing Homeline components and panel infrastructure.
  • Dimensions—1.3 in (W) x 4.5 in (D) x 8 in (H)—designed to suit standard panel spaces without crowding adjacent devices.
  • Indoor Use for residential applications, where AFCI protection is most beneficial in living areas and other occupied spaces.

Who benefits: homeowners updating panels to meet contemporary safety codes, remodelers improving risk management on living spaces, and electricians seeking a reliable AFCI upgrade that integrates cleanly with Square D’s HomeLine lineup.

Why choose this AFCI breaker over a standard 1-pole device? It delivers proactive fault detection that helps prevent fires from arc faults, while maintaining a familiar form factor and straightforward installation within HomeLine-compatible panels. Its 120V, 20A rating covers many everyday circuits, from outlets to lighting runs, making it a practical, code-friendly choice for adding essential protection where it’s most needed.

Practical tips: verify your panel accepts HomeLine plug-in AFCI breakers, turn off the main power before installation, and follow the panel’s labeling for the correct position of a single-pole AFCI device. If you’re upgrading multiple circuits to AFCI protection, consider a coordinated approach with other Homeline devices to maintain consistent protection and panel aesthetics.
