Zerosurge avoids a discusson about earthing. Typically
destructive transients would go right around the Zerosurge
protector using the ground wire. Better to avoid discussion
even of that safety ground wire. Zerosurge sells series mode
protectors. By themselves, series mode protectors are
ineffective. Manufacturer hopes a 'dam' will stop, block, or
absorb the flood (destructive transient).

However Zerosurge protectors can be effective if
supplementing a protection system. If used in conjuction with
a properly earthed 'whole house' protection system, then the
Zerosurge protector acts like a 'dike'. Major difference
between a dam and a dike. A dam never stops, blocks, or
absorbs the destructive flood. But dikes help divert the
destructive flood downstream. This means earthing
(downstream) is essential for series mode protectors to be
effective.

Appliances already contains a dike. Internal protection
that can be overwhelmed if the primary and secondary
protection systems are not installed. What is the most
critical component of primary and secondary protection
systems? Earth ground. But Zerosurge avoids that discussion.

The protection built into appliances is sufficient when part
of a protection 'system'. Internal protection alone is
insufficient without the primary and secondary protection
'systems'. Internal protection can be overwhelmed by
trasnsients that occur typically once every eight years. From
trivial transents created by refirgerators, dishwasher, and
furnace (also called noise), the appliance protection is more
than sufficient.

What is this transient picked up by a building's grounding
system especially during thunderstorms? If that transient
was so destructive, then nearby lightning would destroy
electronics literally tuned to the destructive frequencies of
lightning - AM radios. How many AM radios inside cars are
damaged after every thunderstorm.

Why is that damage number virtualy zero? Because those
mythical surges created by nearby lightning strikes are
promoted only on myth - without numbers. Any transient
created by nearby lightning on the ground wire is made
irrelevant by protection inside the appliance.

However, plug-in (point of use) protector do create other
internal transients. Induced transients are created when a
plug-in protector tries to earth a transient on the safety
ground wires. Safety ground wires are bundled with all other
wires. Any transient being earthed by a plug-in protector now
induces transients on all other wires. IEEE papers discuss
this problem. Earthing a transient on wires bundled with
other wires only complicates transient solution. Just another
reason why plug-in protector are ineffective.

Effective 'whole house' protectors earth a transient on
wires separated from other wires. But again, notice that
Choreboy does not ask about earthing. How a 'whole house'
protector is earthed determined protection. Described are
induced transients that can be created when the electrician
does not properly install a 'whole house' protector or when
using plug-in protectors.

A protector is only as effective as its "connection to and
quality of" earth ground. Something that Zerosurge avoids
discussing to sell their product. It's called lying by
telling half truths - or propaganda.

Choreboy demonstrates another myth:
.. the power company's grounding rods will pick up the surge
and bring it right to your house.
An example of 'lying by telling half truths'. A problem
eliminated when using the single point earth ground. Again,
the primary protection system is demonstrated by these
pictures:
http://www.tvtower.com/fpl.html
If the primary protection system is compromised, then extra
stress is placed on a secondary protection system. And if no
secondary protection system exists, then a plug-in protector
may provide the transient with potentially destructive paths
through your household appliances.

Again Choreboy muddies the water:
Earth ground is for human protection, ...
Yes. And it is also required for transistor safety - as was
posted both previously and repeatedly. Bottom line: the
plug-in protector provides no effective protection and can
even contribute to damage of the adjacent appliance. I have
even traced such damage through a network of powered off
computers. But then I learned by doing the work - fixing
things at the electronic component level and then kept asking
why. Choreboy instead claims:
A plug-in protector will keep it from killing your computer.
This posted without a single fact or number to prove his
point. He would recommend plug-in protectors that are even
undersized- too few joules? Unfortunately, he recites half
truths and myths promoted by those plug-in protector
advocates. He even denies a basic concept. What does
lightning seek? Earth ground. What did Franklin even use to
protect church steeples? Earthing. Instead Choreboy states:
Earthing once cost me a computer.
Then he contradicts himself:
Zero Surge says a protector won't protect your equipment
if the earth grounds aren't bonded.
Which is it? Earthing causes damage or earthing is necessary?

Choreboy later admits to defective earthing. Meanwhile,
earthing for electronics protection was well proven even
before WWII. How can Choreboy deny this? He does not even
know what inside each appliance was damaged. A dead body is
best evidence. But one mustfirst learn the underlying
theories. Unfortunately, Choreboy now recites propaganda from
plug-in protectors advocats - much like those religous leaders
who insisted the sun goes around the earth. One who learns
also performs an autopsy. Those who worship myths from
plug-in protector advocates, instead just somehow know - facts
be damned.

Choreboy had damage due to defects in his earthing system
which he eventually admits to. But he still does not ask a
single question as to how to fix his earthing system. He just
knows a grossly overpriced and undersized plug-in protector is
effective. This even though numbers previously demonstrated
why his stereo and TV could be damaged; and internal
protection inside the computer protected the computer.

Choreboy eventually admits why his protection system did not
work:
I have two points here. I needed four points at the farm
to stop damage.
Ironic. Previously he posted that earthing causes damage?
Now he admits a violation of single point earthing
principles. Instead we consult those who do the science. A
figure from the National Institute of Standards and Technology
demsonstrates how multiple grounds cause damage to a fax:
http://www.epri-peac.com/tutorials/sol01tut.html
But again, I am discussing what provides effective
protection. Earthing. What Choreboy avoids learning about
and yet assumes is not effective? Earthing.

Choreboy suffered damage to TV and stereo. How does an AC
line surge enter these appliances? Incoming on AC electric
hot wire. Outgoing paths include the properly earthed
antenna, or via speaker or antenna wires draped on floor, on
baseboard heat, against chimeny, on lioleum tile, etc. Other
earthing paths could also exist. Two wire appliances are
damaged when those transients are not properly earthed (which
BTW has nothing to do with a safety ground wire on appliance
power cord). A surge may find destructive paths through and
damage transistorized appliances because, as Choreboy now
admits, his earthing system is defective.

For those who want real world protection at about $1 per
protected appliance: the protector is only as effective as
its earth ground.

Unfortunately, Choreboy's knowledge comes from sources of
propaganda such as Zerosurge and from myths promoted by
plug-in protector advocates. He even now denies the critical
need for single point ground, as even the NIST says is
necessary. His defective earthing suggests why he suffered
unnecessary appliance damage. Damage from a transient so
trivial as to not even overwhelm protection inside a computer.

The astronomers who first said earth revolved around the sun suffered
because their observations contradicted theory. The guy who found that
medal objects had buoyancy also suffered for contradicting theory.
...

Is the protection built into a computer undersized?

No wonder those plug-in manufacturers avoid all
discussion about earthing.

Zero Surge used to discuss it on their website.
...

No, the grounding conductor in your wiring could pick up a surge at
various points in a building, especially in a thunderstorm.

BTW, the utility already has installed protection on the
utility wires. You should inspect this protection - the
primary protection:
http://www.tvtower.com/fpl.html

It's no protection for computers. If lightning hits in your area, the
power company's grounding rods will pick up the surge and bring it right
to your house.
...

All that matters to electronic gear is whether it's
connected to conductors with large voltage differences.
...

Earthing once cost me a computer. A lightning surge came in the power
company's grounded conductor, through the whole-house protector to the
120 line, from that line through the computer to modem to the phone
line, from there through the telco entrance lightning protector to the
telco entrance earth ground.

I discovered the problem and bonded the grounds before the next strike.
Zero Surge says a protector won't protect your equipment if the earth
grounds aren't bonded.

Choreboy suffered damage even with a 'whole house'
protector. That means he should begin by asking questions
about his earthing system.

The only electrical path to my stereo and TV was from the hot wire to
the neutral. There was no ground wire. The antenna was rabbit ears.
...

If there is any other path by which a ground surge can affect you, a
single-point earth ground is a hazard to people and equipment. I have
two points here. I needed four points at the farm to stop damage. A
lineman I know needed three points at his house.
