Re: Whole House Surge Protector?

I don't see how this could protect anything. Wouldn't the surge go out to every circuit?

Can someone explain how these things work?
They work by either shunting the surge across the hots or shorting the surge to ground. The theory of operation is the surge protector takes the brunt of the surge until it either the surge clears or opens a protective device (fuse/breaker) ahead of the surge protector isolating all downstream equipment from the source of the surge.

This is one of the reasons the first line surge protector should be installed at the service entrance. Then if needed secondary protectors can be installed on branch circuits as required. Try to stop the surge ahead of the point where it enters the building and before internal distribution.
