Buying Guide: Key Considerations for GFCI Breakers
- Electrical system compatibility: Confirm voltage (120V vs 240V) and the number of poles required by your panel and circuit plan.
- Protection type: Choose between GFCI-only, AFCI-only, or dual-function AFCI/GFCI breakers based on location and code requirements.
- Current rating and interrupting capacity: Match the breaker’s amperage rating to the circuit load and ensure adequate interrupting rating (AIC) for safety.
- Self-test features: Self-testing helps verify device functionality without manual checks; preferred for critical installations.
- Mounting and installation: Determine whether plug-in, bolt-on, or other mounting styles suit your panel type and DIY comfort level.
- Environmental suitability: For damp or wet locations (kitchens, baths, outdoor areas), ensure the breaker is rated for those conditions.
- Brand and warranty: Reputable brands with solid warranties offer longer-term reliability and support.
