Surge Protection for Properties with Multiple Dwellings.
Many buildings only include one SPD located at the main incoming load center and do not cascade SPDs throughout
the building as recommended by IEEE (Institute of Electrical and Electronics Engineers). Adding or cascading QSPDs
can increase the modes of protection and the surge capacity for your entire home grid.
