Buying Guide
- Outdoor vs indoor rating: Outdoor panels require weather-resistant enclosures, knockouts, and corrosion-resistant finishes. Indoor panels prioritize compact footprint and aesthetic compatibility with living spaces.
- Main breaker capacity: A 200A main is common for modern homes, but assess service size, panel space, and future loads (EV chargers, ACs, etc.).
- Expansion potential: Look for panels with more spaces or generous bus bar space to accommodate future circuits without rewiring.
- Neutral and grounding: Some panels come with plug-on neutral options or ground bars; verify compatibility with your local electrical code and wire types.
- Bus material and durability: Copper bus bars offer excellent conductivity; copper is often paired with rust-resistant enclosures for longevity.
- Installation kit contents: Some panels include a full breaker kit; others may require purchasing breakers separately. Plan for the required breaker types and slots.
- Compliance and listings: Ensure UL listing and local code compliance. Outdoor panels should be NEMA-rated for exterior use and rain exposure.
- Wiring space and layout: Consider panels with generous bend space and clearly accessible wiring paths to simplify installation and future reconfiguration.
- Warranty and support: Check manufacturer warranties and availability of replacement parts for long-term maintenance.
- Compatibility with existing service: Verify voltage, 120/240V compatibility, and whether the panel supports plug-on neutral if you plan to upgrade from an older setup.
