Circuit Breaker Panels

Match the panel's amperage rating to your service entrance (commonly 100A, 150A, or 200A), ensure the number of circuit spaces meets current and planned circuits, verify compatibility with your main breaker and bus bar type, and choose a panel listed for indoor or outdoor use as required

Look for listings from recognized testing labs (for example, UL or equivalent), correct voltage and amperage markings, short-circuit current rating (SCCR) appropriate for the installation, and manufacturer instructions that meet local electrical code requirements

You can often add circuits with a larger main breaker or subpanel if the service has capacity; cost depends on panel amperage, number of spaces, whether a main breaker or main lug type is needed, and local labor and permit fees. Always have upgrades performed or approved by a licensed electrician

A main breaker panel includes a main disconnect built into the panel, a main lug panel requires a separate upstream disconnect, and a subpanel is fed from a main panel to provide additional circuit spaces; selection depends on service setup and local code

Keep the panel accessible and free of dust and moisture, periodically check for signs of overheating or corrosion, tighten loose connections only by a qualified electrician, and test ground-fault/arc-fault breakers per manufacturer guidance

Price is influenced by amperage rating, number of circuit spaces, main breaker vs. main lug configuration, indoor vs. outdoor enclosure, and brand; panels in the residential/tools & industrial category commonly span from budget options under $50 to higher-capacity models in the low hundreds, with average prices around the low hundreds

Yes; many panels require breakers listed for use with that panel's bus design. While some breakers are cross-compatible, always confirm the panel's labeling or manufacturer documentation to ensure breakers are permitted for use in that panel
