A building with old wiring which is unable to be rewired because of architectural obstacles such as churches and synagogues specifically needs surge protection because of their lack of good insulation in their wiring.
Professional surge protection is also strongly recommended for any public facilities such as schools, laundromats, supermarkets, and other highly occupied areas where safety is important.
Surge Protection is also a necessity for businesses which require clean power for sensitive equipment such as hospitals, banks and medical offices. Fortunately surge protection manufacturers also offer a system specifically designed for single family and multi-family homes as well.
