I want to make my whole house surge protected, there are several solutions available
- You can install MOV based surge protection on the entire house in line entry point - first line of defense
- You can use socket surge protection, MOV based as well - third defense line, protecting individual appliance
- Junction box SPD if such a thing exists - second line of defense.
How much of such defensive layers of surge protection makes sense to install from economical and technical point of view?
