Do you think that tiny circuit will stop what three miles of sky
could not?
Where does that surge energy go? Does this circuit stop or absorb
that energy?
Notice the ground wire simply carries the surge completely around
the circuit. And other components divert that surge energy into the
ground wire where it connects directly to the appliance on right side
connector.
Most of what would work in this circuit is already inside every
appliance. Internal appliance protection assumes that surge energy
gets earthed before entering the buillding. Again, where does that
massive energy get dissiipated? In this circuit? In the appliance?
Of course not.
Destructive surges seek earth ground. Once permitted inside a
building, destructive paths to earth may be everywhere. Protection
means the surge is given earth BEFORE entering a building.
Protection means massive surge energy gets absorbed and dissipated
harmlessly in earth. IOW any wire that would carry a surge into the
house must first be earthed where it enters the building.
Did you know all telco lines already have a 'whole house' protector
installed for free? What actually provides protection? Not that
protector. Telco 'installed for free' protector is so effective when
connecting each wire in that cable to earth ground - ie 'less than 10
feet' to earth. Where is surge energy harmlessly dissipated? In
earth and before that surge can enter a building.
Whereas cable and telephone have protection installed for free, AC
electric does not. So that protection already inside all appliances
is not overwhelmed, install (and properly earth) one 'whole house'
protector. See GE, Siemens, Square D, Kieson, Cutler-Hammer,
Intermatic, Levition, et al for effective solutions. No such
solutions are sold by APC, Belkin, Tripplite, Monster Cable, etc.

See that wire that is not drawn as a wire? It connects a surge on
any incoming wire to directly to the 'protected' appliance. Just one
reason why such circuits can sometimes provide surges with even more
destructive paths around protection inside the appliance. Instead
earth the surge before it even enters a building.
