Buying Guide
- Indoor vs outdoor: Outdoor panels require weatherproof enclosures and corrosion resistance; indoor panels prioritize compact design and ease of access.
- Capacity and space: Match amperage rating (70A, 100A, 125A, etc.) with your sub panel load expectations and future expansion needs. Consider the number of spaces and compatibility with tandem or twin breakers if you foresee dense circuiting.
- Bus material and grounding: Copper bus bars offer excellent conductivity; ensure proper grounding provisions and compatibility with your service panel configuration.
- Main breaker vs main lug: Main breakers simplify power shutdowns; main lug panels rely on external disconnects but can be more versatile for sub panel layouts.
- Durability and installation: Look for NEMA ratings, enclosure material, and mounting options that suit your environment (indoor vs outdoor, RV or mobile use).
- Code compliance: Verify panel type, labeling, and compatibility with local electrical codes and the original panel you’re expanding from.
- Ease of wiring: Favor panels with clear labeling, accessible bus bars, and included mounting hardware to reduce install time and errors.
