The NEC 2020 Code requires Surge Protection devices for new and replaced service equipment supplying dwelling units.
Using Generac’s whole-house Surge Protection Device (SPD) helps
protect sensitive electronics like mobile phones, laptop computers, TVs
and smart appliances from voltage spikes caused by lightning strikes,
downed power lines, and routine utility switching activity. The ESFI
estimates homes have on average $15,000 worth of these sensitive
electronics that can be damaged by surges. The new Surge Protective
Device (SPD) is a convenient, cost effective solution to protect
electrical devices and appliances.
It has thermally protected MOVs (metal oxide varistors) that
reduce the risk of thermal damage. It is also compact,
weather-resistant, and can be installed quickly, in minutes.
