Buying Guide
- Compatibility: Confirm the breaker type (QP, QPF2, THQL, QO, etc.) matches your panel model. Mismatches can affect fit, safety, and warranty.
- Interrupt Rating: Aim for at least 10 kAIC where possible to ensure fast and safe interruption of fault currents in typical U.S. homes.
- GFCI Requirements: For kitchens, baths, garages, and outdoor outlets, choose appropriate GFCI breakers (60 A, 2-pole or 4-pole as required) to meet NEC spacing and safety rules.
- Environmental Use: If the panel is exposed or subject to moisture, consider weather-resistant enclosures and enclosure-rated components (e.g., NEMA 3R) for outdoor use.
- Panel Brand Ecosystem: Using breakers from the same brand as the panel can simplify installation and support; however, cross-compatibility options exist with documented compatibility lists.
- Future Upgrades: Plan for potential panel expansions by selecting breakers and panel types that support additional circuits without rework.
- Warranty and Certification: Verify UL/ETL listings and manufacturer warranties. Replacement and support are easier when sticking to well-supported lines.
- Installation Practicalities: Some models offer plug-in connections or insta-wire features to speed up installation; ensure your enclosure design accommodates these features.
- Safety Practices: Always de-energize and lock out the main breaker before servicing panels. Use proper PPE and follow local electrical codes.
