Buying Guide: Key Purchase Considerations
- Configuration: Decide between main breaker and main lug panels. Main breaker panels simplify disconnection of all circuits at once, while main lug panels may be suitable for existing service with a separate main disconnect.
- Amperage and space: Match panel amperage (e.g., 100A, 125A) to anticipated load. Ensure there is enough spaces for current and future circuits.
- Enclosure rating: For indoor installations, a NEMA 1 steel enclosure offers dust protection and durability, while higher ratings (e.g., NEMA 3R) suit damp or outdoor environments.
- Neutral and grounding: Some panels include a plug-on neutral, which can simplify wiring. Verify required grounding methods for your local code.
- Expansion potential: Consider whether the panel supports tandem or twin breakers if future circuit growth is expected, and whether service panels are compatible with existing breakers.
- Brand and support: Reputable brands (Square D, Siemens, ABB) typically provide better warranty support and easier availability of compatible breakers.
- Safety features: Look for features such as clear labeling, dead-front design, and secure termination spaces to reduce arc-flash risk and improve wiring organization.
