Buying Guide: Key Purchase Considerations
Protection level and type: Decide between Type 2 (upstream protection at the panel) and Type 1/Type 2 combinations. Type 2 devices are common for whole-home protection, while Type 1 may be used at service entrances in certain codes.
Panel compatibility: Verify that the surge protector fits your panel’s space and connector style. Some units occupy two breaker spaces; others install in-line with a plug-on neutral design.
Surge current rating: Higher ratings (kA) generally indicate greater protection for a wider range of devices. Consider your home’s electronics, HVAC, and internet infrastructure when evaluating ratings.
Installation flexibility: Look for devices that are described as universally compatible or adaptable to various load centers. Quick-connect or modular designs can simplify installation and future upgrades.
Environmental suitability: Indoor vs. indoor/outdoor use matters for weather exposure. NEMA ratings and enclosure materials should align with your installation environment.
Code compliance: Ensure the device complies with relevant standards (for example UL 1449 3rd Edition) and local electrical codes, which may influence the appropriate type and placement of the SPD.
Maintenance and indicators: Some units include LED indicators or status alarms. Clear indicators help verify operational readiness after installation or during power events.
Cost and warranty: While prices are not listed here, consider overall value including efficiency, warranty terms, and ease of replacement or service life within your home’s electrical system.
