Buying Guide
- Outdoor vs indoor: Outdoor panels require weather-resistant enclosures (NEMA 3R) and corrosion protection. Indoor panels use NEMA 1 enclosures and are typically easier to install in finished spaces.
- Space and circuits: Choose based on current load and future expansion plans. Panels with 32 spaces and up to 64 circuits suit growing homes; 20-space panels fit smaller upgrades.
- Main breaker rating: A 200A main is standard for modern residential service. Verify service entry capacity and compatibility with your utility disconnect.
- Included breakers: Some kits arrive with a bundled set of THQP or THQL breakers. Ensure compatibility with your preferred breaker type.
- Material quality: Look for copper bus bars and galvanized enclosures for durability and better electrical conductivity.
- Installation considerations: Plan for accessible labeling, clearance around the panel, and local code compliance. Outdoor installations may require frost-proof or weatherproofing steps.
