Buying Guide
- Compatibility: Verify that the panel type (load center vs. enclosure) matches your electrical service and that breakers are compatible with your bus bars.
- Indoor vs. Outdoor: Outdoor-rated enclosures require weatherproof sealing, corrosion-resistant finishes, and proper enclosure ratings (NEC/UL). Indoor panels may be more compact but need protection from moisture.
- Ampacity and Circuits: Decide how many spaces and circuits you need now and in the near future. A 30A unit may be sufficient for a single RV site or a small outdoor shed, while a larger enclosure might be preferable for full outdoor power distribution.
- Certification: Look for UL and ETL listings, CSA compliance, and NEC conformity. Listings help ensure safe operation and compliance with local codes.
- Installation Considerations: Check whether the unit requires pre-wiring or is ready-to-install. Consider space, mounting options, ventilation, and ease of access for maintenance.
