Buying Guide
Key purchase considerations for a 200A, 40-space panel:
- Indoor vs outdoor use: choose enclosures with appropriate NEMA ratings for climate exposure (indoor panels require basic protection, outdoor panels should be weather-rated).
- Main breaker vs main lug: main breaker panels include a factory-installed main disconnect; main lug panels require separate main gear or service disconnect in some installations.
- Plug-on neutral capability: reduces wiring complexity and can support arc-fault protection, but verify compatibility with your breakers and local codes.
- Space and wiring clearance: ensure enough space for full-size, tandem, or quad breakers and adequate bending space for conductors.
- Grounding and bonding: confirm the availability of ground bars and the ability to accommodate multiple grounds for safer installations.
- Equipment compatibility: ensure breakers and accessories are compatible with the panel brand and model to meet NEC requirements.
- Expansion considerations: plan for future circuits, ensuring the chosen model supports additional breakers or tandem configurations if needed.
- Service entrance requirements: if installing outdoors or near property lines, verify local permits and electrical code compliance for outdoor service equipment.
