Re: Surge Protection Residential Whole House

How do these work? How can they protect 100+ Amp service with such small wires?

The load isn't going through those wires. The surge protector is wired parallel to the load as a shunt to absorb the surge energy. The surge itself is expected to only be a short pulse and not long enough to heat the wires.

These are not for high amperage lightning protection but simply over voltage spike protection.

Lightning would fry that real fast, so i hope no one thinks it's good for direct lightning strikes, it isn't. just surge protection.
