No surge device protects from a direct lightning strike to the home itself. It significantly reduces damage and handles common indirect surges almost completely. Layering with quality plug-in strips is best.
Most quality units last 5 to 10 years in typical Derwood conditions. The indicator light signals when replacement is due.
No. The device installs at the main panel. Manufacturer warranties and insurance recognition typically require licensed installation.
Many insurers in Derwood, MD offer rate considerations for properly installed surge protection and better claim outcomes.
