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.

Why this AFCI breaker matters

Arcing faults are a common and dangerous electrical fault condition. This AFCI breaker detects non-visible arcing events that conventional breakers may miss, then trips to prevent potential fires. It complements standard overcurrent protection, delivering a stronger safety net for your home’s wiring, outlets, and devices.

Ideal applications

Perfect for branch circuits in living spaces, bedrooms, hallways, and other indoor areas where enhanced arc protection is warranted. Use it on circuits that power lighting, receptacles, or general-use loads to bolster overall electrical safety.

Simple guidance for use

Verify panel compatibility (single-pole, 120V, plug-in type) and ensure the unit is the correct amperage (20A). Install per local codes and the included instructions. If you’re unsure about panel compatibility or installation requirements, consult a licensed electrician for a safe and compliant setup.
