Most people think of surge damage as a lightning problem. Lightning is one cause, but it is not the only one. Utility switching, grid fluctuations, downed lines, and large equipment cycling can also create voltage spikes.
Modern homes contain more sensitive electronics than ever: smart appliances, HVAC control boards, routers, security systems, computers, entertainment systems, and EV charging equipment. Replacing even one major component can cost far more than prevention.
A whole-home surge protective device is installed at the electrical panel. Its job is to reduce damaging voltage before it spreads through branch circuits.
It does not replace point-of-use protection for delicate electronics, but it creates a stronger first layer for the entire home.
If your home has expensive smart tech, an EV charger, or newer appliances, surge protection deserves a serious look.
