The required religious belief in earthing.
Repeating:
The IEEE guide makes clear that plug-in suppressors work by CLAMPING,
not earthing. The IEEE guide explains earthing occurs elsewhere.

Good reason why Ben Franklin's lightning rod diverted (clamped)
lightning so that surges did not conduct destructively through wooden
church steeples. Earth ground. Good reason why industry
professionals in telephone switching centers, commercial broadcasting
stations, US military facilities, and 911 emergency response centers
earth 'whole house' type protectors. Surges seek earth ground. Good
reason why Will Honea learned from experience; earthing essential for
protection. Good reason why 1910 ham radio operators would suffer
electronics damage even with their antenna lead inside a mason jar;
damage stopped when antenna lead was earthed. Same good reason why TV
and FM radio electronics atop the Empire State Building are struck 25
times annually without damage. Even 1930s GE and Westinghouse papers
defined that protection: earthing.

No earth ground means no effective protection. So why does Bud's
guide Page 42 Figure 8 show a protector too far from earth ground and
too close to the TV? Why is 8000 volts destructively through the TV
acceptable? Bud misrepresents that guideline. Protectors misplaced -
without earthing - can even damage appliances. IEEE Standards - Red
Book, Green Book, etc - also made that same statement. Page 42 Figure
8 demonstrates a protection *clamping* a surge destructively through
a TV.

Bud's own NIST guide says protectors work by grounding? As defined
by IEEE, protectors shunt (clamp, connect, bond, divert) a surge to
earth ground. Bud does not challenge this. He continues to post a
half truth. Protectors clamp. Yes, and what do they clamp to?
Destructively (8000 volts) through a 'too close' TV? Or safely to
earth when the protector is a 'whole house' type - with that dedicated
earthing wire?

All of Bud's citations were used to expose his half truths. Page 42
Figure 8 shows a protector too far from earth ground *clamping* 8000
volts destructively through a TV. Page 8 of 24 (paper page 6) even
says a protector must
... simply divert it to ground, where it can do no harm."
Bud ignores facts from his own citations to recommend ineffective
plug-in protectors.

He has no facts. So he posts insults: 'drivel', "old political
trick", and "religious belief". His own citations even contradict his
claims. So he posts insults.

Responsible manufactures such as Leviton, Intermatic, Cutler-Hammer,
Square D, Siemens, and GE sell effective 'whole house' protectors.
Solutions that may cost less than $50 in Lowes and Home Depot.
Solutions that costs about $1 per protected appliance. Installed so
that protection already inside every appliance is not overwhelmed.

Each protector made effective by a dedicated earthing wire.
Earthing connection should be 'less than 10 feet', no sharp bends, not
inside metallic conduit, separate from other non-earthing wires (to
elimiinate induced transients), and joins all other earthing wires at
the same earthing electrode. The single point earth ground. Simple
enhancements mean effective surge protection. Effective protector
because of that electrically short connection to a single point earth
ground. Earthing that meets and exceeds post 1990 National Electrical
Code requirements.

Plug-in protectors will not discuss what is necessary for effective
protection.

Above is only 'secondary' protection. Responsible homeowners also
inspect their 'primary' protection 'system':
http://www.tvtower.com/fpl.html

But again, surge protection is about earthing - as Franklin
demonstrated in 1752. As Westinghouse and GE science papers
demonstrated atop the Empire State Building. How protection is
installed in every town where damage from lightning must never
happen. A protector is only as effective as its earth ground which is
why those responsible manufacturers sell 'whole house' protectors with
an absolutely essential earthing wire.

And then those 'scary pictures' when plug-in protectors are grossly
undersized.

Even the backup system needs one, properly earthed, 'whole house'
protector.
