Default DIY surge protection...

Do you magically make that energy just disappear? Of course not.


Where the energy goes has often been explained (including this thread)
but w's religious blinders prevent the words from penetrating.


According to Bud, that energy magically disappears. Clamping
somehow make energy disappear? He says that often. Meanwhile the
NIST (his own citation) says what happens when the protector cannot
connect that energy to earth:
The best surge protection in the world can be useless if
grounding is not done properly.


Or Dr Martzloff who discusses the same problems in his 1994 paper.
A plug-in (point of connection) protector can even cause damage to
nearby appliances. It is the first conclusion in that IEEE paper:
Conclusion:
1) Quantitative measurements in the Upside-Down house clearly show objectionable
difference in reference voltages. These occur even when or perhaps because, surge
protective devices are present at the point of connection of appliances.


Each layer of protection is defined by the only item that makes
surge energy harmless. Protection is always about where energy
dissipated. And why more responsible companies sell the 'whole house'
protector. A protector is only as effective as its earth ground. An
effective protector also costs tens or 100 times less money per
protected appliance.
