Buying Guide: Key Purchase Considerations
- Panel compatibility: Ensure the SPD matches your panel type (Type 1, Type 2, or specific brand compatibility) and check for space availability in the service panel.
- Surge rating: Higher per-phase ratings (e.g., 35–36 kA) provide stronger protection for modern electrical loads and electronics; match rating to home size and critical devices.
- Indication and monitoring: Some models offer mechanical indicators, LEDs, or status displays to show protection status. Consider visibility preferences for maintenance checks.
- Indoor vs. outdoor: Outdoor-rated enclosures support harsher environments; indoor units suit standard basements, garages, or utility rooms.
- Installation considerations: Confirm whether professional installation is recommended or required by local codes. Review NEC guidelines (Article 230.67 references type of SPD required for dwellings).
- Brand and warranty: Reputable brands often provide longer warranties and clearer support for panel integration and replacement after surges.
- Maintenance and replacement: Some SPDs may require periodic testing or replacement after significant surge events; verify service life expectations with the manufacturer.
- Cost vs. protection balance: Weigh each unit’s surge capacity, panel compatibility, and installation ease against project budget and potential electrical load priorities.
