Buying Guide

Match amperage and circuit count

Choose panels and load centers whose amp rating and number of ways fit your service and expected circuit expansion (e.g., 16-circuit, 125A load centers or 18-way distribution boxes)

Check enclosure protection

Select an enclosure with an appropriate IP rating for the installation environment; IP65 waterproof enclosures are suitable for damp or outdoor-adjacent locations

Verify breaker compatibility

Ensure breakers or accessories are compatible with your existing panel type (e.g., Pushmatic-compatible replacements or Square D Homeline/QO-compatible interlocks)

Consider safety accessories

Look for surge protection and interlock kits that add whole-house surge suppression or safe generator connection without altering main service components

Prioritize reputable brands and ratings

Prefer products from established electrical brands and those with consistent user ratings to reduce risk in critical electrical components
