Clamping to what?

Clamping to earth ground. Destructive surges seek earth ground.
Surges enter on any wire to find earth ground, destructively, via
electronic appliances. Or surges are shunted (clamped, bonded,
diverted, connected, equalized) to earth ground without damage.

Bud is promoting for plug-in protector manufacturers. Since those
protectors have no earthing connection, then Bud must pervert the
definition of clamping.

Either that surge is clamped to earth where it enters the building
OR it is clamped to earth, 8000 volts destructively, via the adjacent
TV. Bud's own citation Page 42 Figure 8 demonstrates it.

Obviously a protector cannot be clamped to nothing. And yet
nothing is what Bud calls protection. No earth ground means no
effective protection. Even the NIST says a protector must ground
surges - from Bud's other citation page 6 (Adobe page 8):
You cannot really suppress a surge altogether, nor
"arrest" it. What these protective devices do is
neither suppress nor arrest a surge, but simply
divert it to ground, where it can do no harm.

Divert it to ground which is also called clamping, shunting, or
bonding to earth. Destructive surges obtain earth ground safely via
an earthed 'whole house' protector or destructively via household
appliances. Which item do you want clamping that surge to earth?
Page 42 Figure 8 shows a TV clamping destructively because of a plug-
in protector.

Ben Franklin demonstrated other surge conductors - ie wood church
steeples. To protect church steeples, Franklin clamped lightning to
earth ground using Franklin lightning rods. How did Franklin create
church steeple protection? He shunted, diverted, conducted, clamped,
bonded lightning to earth ground. Now lightning did not be conducted
destructivley by wood in a steeple.

Bud assumes tables, linoleum, wall paint, concrete floors, etc are
not conductive. That 'TV destructive current' can be incoming from a
plug-in protector and 8000 volts destructively to earth even via the
tabletop and linoleum tile. Just another reason why effective
clamping is to earth beneath a building. Just another reason why Page
42 Figure 8 shows a plug-in protector clamping (shunting) a surge 8000
volts destructively through the TV.

No earth ground means no effective protection; as demonstrated by a
plug-in protector clamping a surge destructively thru that TV.
