Go to Lowes. Ask him for the Cutler-Hammer 'whole house' protector
that costs less than $50. That protector (model CHSPMICRO) is for
50,000 amp surges. Don't take my word for it. Read the numeric
specs. It will connect a direct lightning strike harmless to earth
if connected to a breaker box that connects 'less than 10 feet' to
earth ground. Massive energy dissipates harmlessly in earth. That
Cutler- Hammer protector is required to protect the Tripplite.

It is always about where energy dissipates. Why does that
Tripplite
numeric specifications not list protection from each type of surge -
in numbers? Because it only claims to protect from surges that are
typically not destructive. How does its hundreds of joules absorb
surges that are hundreds of thousands of joules? Ask bud for those
specs that claim protection from each type of surge. He will never
provide those specs.

A protector is only as effective as its earth ground. Which is why
the Cutler-Hammer protector - about $1 per protected appliance - is
also the superior solution

OK, I can't find it on their website.

Read here. You say hundreds of thousands of Joules.
This one has 100KA at 840 Joules


The little bitty Tripplite laptop protector is over a 1000 Joules.

This is twice the amperage as you state.

http://www.drillspot.com/products/423212/Supco_SCMPLUS_Surge_Protector

grge

surge protectors don't ABSORB strike energy,they shunt it to
ground,providing a low resistance path to ground.
Instead of the energy passing thru your equipment on it's way to ground.

A higher Joules rating means the device absorbs less than a lower rated
device,and thus can divert more energy before IT blows up.

One more limit is your home wiring;how much strike energy can those lines
carry? (to ground)

and how good is the house ground?

So service panel suppressors absorb hundreds of thousands of joules?

Of course not.

As explained early in this thread, the amount of energy that can reach a
plug-in suppressor is surprisingly small. The information came from
Martzloff, the NIST expert on surges.

That $3 power strip with some ten cent
protector parts is selling for how much?

One of the suppressors I use has 3 MOVs with ratings of 590J each.
Provide a source for a 590J MOV for $.10.

Go to Lowes. Ask him for the Cutler-Hammer 'whole house' protector
that costs less than $50.

Last I heard this didn't exist. Apparently Greg couldn't find it either.

Why does that Tripplite
numeric specifications not list protection from each type of surge -
in numbers?

Why does service panel suppressor manufacturer SquareD not list "each
type of surge in numbers"? Because it is nonsense - just another bogus
argument. UL listed suppressors have MOVs from H-N, H-G, N-G. That is
all possible combinations and all possible surges.

How does its hundreds of joules absorb
surges that are hundreds of thousands of joules?

How does "hundreds of joules absorb surges that are hundreds of
thousands of joules" in a service panel suppressor? It doesn't. Neither
service panel or plug-in suppressors protect by absorbing energy. They
absorb some energy in the process of protecting.

Ask bud for those
specs that claim protection from each type of surge. He will never
provide those specs.

I have provided specs often, so have others. They are always ignored by
westom, who just continues to repeat his lies.

A protector is only as effective as its earth ground.

The religious (immune form challenge) belief in earthing.

Why aren't flying airplanes crashing every day when they are hit by
lightning? Do they drag an earthing chain?

Still missing - answers to simple questions:
- Why do the only 2 examples of protection in the IEEE guide use plug-in
suppressors?
- Why does the NIST guide says plug-in suppressors are "the easiest
solution"?
- Why does the NIST guide say "One effective solution is to have the
consumer install" a multiport plug-in suppressor?
- How would a service panel suppressor provide any protection in the
IEEE example, page 42?
- Why does the IEEE guide say for distant service points "the only
effective way of protecting the equipment is to use a multiport
[plug-in] protector"?
- Why did Martzloff say in his paper "One solution. illustrated in this
paper, is the insertion of a properly designed [multiport plug-in surge
suppressor]"?
- Why does Dr. Mansoor support multiport plug-in suppressors?
- Why don’t favored SquareD service panel suppressors list "each type of

For real science read the IEEE and NIST surge guides. Both say plug-in

Bud's job is
to promote plug-in protectors.

Lacking any valid technical arguments westom attacks those who challenge
his nonsense.

So he will say anything to avoid that
reality.

westom will say anything to avoid the reality that plug-in suppressors
are effective.

The IEEE, NIST, General Electric, Siemens, Leviton, Intermatic, Keison,
and Square D all say they are.

Every responsible source discusses earth as the means of
eliminating those voltage differences.

It is the religious belief (immune from challenge) in earthing.

Everyone is in favor of earthing.

And every responsible source says plug-in suppressors are effective.

The IEEE surge guide explains, for those that can think, that plug-in
suppressors work primarily by clamping the voltage on each wire to the
ground at the suppressor, not earthing. The IEEE says earthing occurs
elsewhere in the system.

To do that means the protector must connect even direct lightning
strikes harmlessly to earth. To connect 20,000 amps (a typical
lightning strike) harmlessly to earth means, at minimum, a 50,000 amps
protector. At 24,000 amps, you would need two of those Grainger
protectors just to do a minimum.

A 20,000A direct lightning strike to a power line will have multiple
paths to earth. The maximum surge current to a house from a much more
powerful lightning is 10,000A according to accepted standards.

The IEEE surge guide recommends - for homes - ratings of 20-70kA, or for
high lightning areas 40-120kA.

westom, of course, is smarter than the IEEE.

More responsible companies make these 'whole house' protector
including General Electric, Siemens, Leviton, Intermatic, Keison, and
Square D.

All these "responsible companies" except SquareD make plug-in suppressors.

SquareD says for their "best" service panel suppressor "electronic
equipment may need additional protection by installing plug-in
[suppressors] at the point of use."

Surges created by motors
are the myth that Bud promotes

westom is prone to hallucinations. "Motors are not a particular surge
threat in a home."

Ask bud for the manufacturer spec that claims protection from
each type of surge. He works in this business.

The lie repeated - 2nd time.

UL is only about human safety. Says nothing about whether a
protector is effective.

Nonsense. As has been detailed previously, a UL listed suppressor has to
suppress a series of surges and remain functional.

He will not even admit he is paid to promote plug-
in protectors - ie that Tripplite.

The lie repeated - 3rd time.

What will that Tripplite do when its hundreds of joules somehow
absorbs surges that are hundreds of thousands of joules? Explode.
Vaporize. Create a human safety problem also seen in these other
scary pictures:
http://www.hanford.gov/rl/?page=556&parent=554

In addition to completely failing to understand how any suppressor
works, westom refuses to understand his own hanford link. It is about
"some older model" power strips and says overheating was fixed with a
revision to UL1449 that required thermal disconnects. That was 1998.
There is no reason to believe, from any of these links, that there is a
problem with suppressors produced under the UL standard that has been in
effect since 1998. None of these links even say a damaged suppressor had
a UL label.

But with no valid technical arguments all westom has is pathetic scare
tactics.

Bud's job is to keep you from learning these realities.

The lie repeated - 4th time.

Plug-in protectors (ie that Tripplite) require
protection that only earthing and the 'whole house' protector can
provide.

Funny - neither the IEEE or NIST surge guides mention that.
Another of westom's hallucinations

Yes, to do what bud is claiming,
you must buy at least 20 plug-in protectors for all over house.

Yet another hallucination.

Did bud forget to mention what his job is?

The lie repeated - 5th time. People with valid arguments don't have to lie.

Still missing - any source that agrees with westom that plug-in
suppressors are NOT effective.

Still missing - answers to simple questions:
- Why do the only 2 examples of protection in the IEEE guide use plug-in

How does it fail? Open - sometimes explosively.

They fail shorted. If not removed from a supply of power they may fracture.

A thermal fuse
disconnects its protector circuit. Leave the appliance connected to
that surge – to fend for itself.

As pointed out previously, in a plug-in suppressor the protected load
may be connected across the MOV and be disconnected with a failing MOV.

If a service panel suppressor fails it leaves the appliance connected to

Earth
one 'whole house' protector so that energy dissipates harmlessly in
earth.

A service panel suppressor is a good idea.

But repeating from NIST surge guide:
"Q - Will a surge protector installed at the service entrance be
sufficient for the whole house?
A - There are two answers to than question: Yes for one-link appliances
[electronic equipment], No for two-link appliances [equipment connected
to power AND phone or cable or....]. Since most homes today have some
kind of two-link appliances, the prudent answer to the question would be
NO - but that does not mean that a surge protector installed at the
service entrance is useless."

A service panel suppressor does not limit the voltage between power and
cable/phone wires, which the NIST surge guide suggests is the cause of
most equipment damage.

A protector is only as
effective as its earth ground.

westom's religious mantra protects him from confusing thoughts - like
plug-in suppressors work primarily by clamping, not earthing.

Ratings are good. I wouldn't buy it because I have never heard of the
manufacturer. I would like to explicitly see that it is UL1449 listed.
"Meets UL" is a manufacturer claim and is not the same as UL listed (UL
tested). The "UL 1449 Clamping Volts" have nothing to do with UL ratings
- a red flag.

grge

surge protectors don't ABSORB strike energy,they shunt it to
ground,providing a low resistance path to ground.
Instead of the energy passing thru your equipment on it's way to ground.

That is probably appreciated by people here, but not in general. Neither
service panel suppressors or plug-in suppressors protect by absorbing
the surge. But they both absorb some energy in protecting.

A higher Joules rating means the device absorbs less than a lower rated
device,and thus can divert more energy before IT blows up.

The energy rating of a MOV - say 100 joules - is the singe event energy
that can be absorbed by the MOV and put it at the defined end of life
(but still functional). If the energy hits are less, say 10 joules, the
cumulative energy rating will be significantly higher than 100 joules.
If the energy hits are far lower, say 2 joules, the cumulative energy
the MOV can absorb will be far larger than 100 joules. A very high
rating means the suppressor is far less likely to fail. I don't expect
my plug-in suppressors with high ratings to ever fail.

One more limit is your home wiring;how much strike energy can those lines
carry? (to ground)

and how good is the house ground?

If a house has a surge current to earth of 1,000A and a quite low
resistance to earth of 10 ohms the system ground will rise to 10,000V
above "absolute" earth potential.

Martzloff has written "the impedance of the grounding system to `true
earth' is far less important than the integrity of the bonding of the
various parts of the grounding system." Make sure the phone and cable
entrance protectors are connected with short wires to the ground at the
power service. (Other systems, like satellite must also be connected.)
If they are, the power and phone and cable wires can rise together. IMHO
'improving' the earthing is less important.

High voltage between power and phone/cable wires is likely a major cause
of equipment damage.

That is not what your protectors do. Others can observe same. A
power strip protector with the 'failed' light on still power
appliances. Because the appliance is not disconnected when the
protector circuit fails. A grossly undersized protector circuit
disconnects as fast a possible to avoid fire. Leaves the appliance
connected to the surge.

Or view pictures from Zerosurge:
http://www.zerosurge.com/HTML/movs.html
They removed all MOVs. ‘Failed’ light said the protector was still
good. And power was still connected to appliance receptacles. Again,
protector circuits disconnected – and appliance remains connected to
the surge.

Bud's NIST citation discusses his protectors:

A very important point to keep in mind is that your surge protector will work by diverting
the surges to ground. The best surge protection in the world can be useless if grounding
is not done properly.

"useless if grounding is not done properly" defines protectors that
bud promotes. I am kind. I only called them ineffective. The NIST
calls them "useless".

A protector is only as effective as its earth ground. Every
protection layer is only defined by THE item that does protection -
earth ground. Earth one 'whole house' protector for secondary
protection. Necessary even to protect protectors that bud promotes.

Also inspect your primary protection system. Again, every
protection layer is only defined by the earthing:
http://www.tvtower.com/fpl.html

bud will post incessently. And never provide one simple fact.
Numeric specs that claim protection from each type of surge. He
promotes high profit plug-in protectors. And still cannot cite even
one manufacturer spec that lists protection from each type of surge.
Of course not. Plug-in protectors are neither designed nor claim to
provide protection from typically destructive surges. But when
selling a $3 power strip with some ten cent protector parts for $25 or
$150, then why tell the whole truth?

Protection - as even defined in all his citations - is only as
effective as its earth ground. Page 42 Figure 8 even shows the
protector earthing a surge 8000 volts destructively through a TV –
because the protector is too close to appliances and too far from
earth ground. Protection is always about where energy dissipates.
How does his protector (hundreds of joules) absorb surges that are
hundreds of thousands of joules? It doesn't. So he does not post
numeric specs. Will not even discuss where energy dissipates.

A protector is only as effective as its earth ground. How do those
hundreds of joules make surges - hundreds of thousands of joules -
just magically disappear? That answer is adjacent to those never
provided numeric specs.

Martzloff what quite clear about what plug-in (point of connection)
protectors can do to appliances. It was the very first conclusion in
his 1994 paper - that discusses where energy dissipates:

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.

What is necessary to protect plug-in protectors? What is necessary
so that plug-in protectors do not make appliance damage easier?
Earthing. And a 'whole house' protector properly connected short (ie
' less than 10 feet') to single point earth ground. Where is surge
energy dissipated when the effective 'whole house' protector is
earthed? Harmlessly outside the building. Then objectionable
differences do not exist in reference voltages.

Why do telcos all over the world not waste money on plug-in
protectors? They put their money where it does protection. Better
earth grounds and a 'whole house' type protector that costs
significantly less money. A protector is only as effective as its
earth ground.

Somehow that 1000 joules protector (that only used 333 and never
more than 667 joules) will magically make hundreds of thousands of
joules just magically disappear? I would say the same thing if my
profit margins were that excessive.

Why is 'cloud to cloud' lightning relevant to protecting household

Where are those numeric specs that claim protection from each type

he wants to discuss flying airplanes.

Read his own citations. The NIST defines bud's protectors:

The best surge protection in the world can be useless if grounding is not done properly.

Numerous IEEE Standards say why bud's protectors do not claim
protection in their numeric specs. From the IEEE Red Book:

In actual practice, lightning protection is achieve by the process of interception of lightning produced
surges, diverting them to ground, and by altering their associated wave shapes.

How does it divert to earth when it does not connect to earth? Does
it magically make energy disappear? Diverting (connectiong, bonding,
shunting, switching) a surge to earth. Then the protector does,
according to the NIST:

neither suppress nor arrest a surge, but simply divert it to ground, where it can do no harm.

A protector is only as effective as its earth ground. So bud wants
to discuss airplanes to avoid reality. Where are those manufacturer
specs that claim protection from each type of surge? NIST and IEEE
say why bud cannot provide them. A protector is only as effective as

westom still refuses to explain how you can protect airplanes without an

plug-in suppressors as an effective protection device. This is the most

the discussion on connecting the protected load across the MOVs. At
least one, and probalby both, of the suppressors I have do that.

Or view pictures from Zerosurge:
http://www.zerosurge.com/HTML/movs.html
They removed all MOVs.

This is indeed a problem if there is a gang of MOV thieves operating in
your neighborhood. Check with your local police.

The NIST
calls them "useless".

If the village idiot was not wearing religious blinders he could read
what the NIST surge guide says:
They are "the easiest solution".
And "one effective solution is to have the consumer install" a multiport
plug-in suppressor.

Necessary even to protect protectors that bud promotes.

I promote only accurate information - like the IEEE and NIST surge guides.

westom promotes his religious beliefs. Just like talking to Jehovah’s
Witness.

bud will post incessently.

westom will post incessantly. His belief in earthing has been challenged
and cracks in his universe may develop.

And never provide one simple fact.

Facts I have provided:
- The only 2 examples of protection in the IEEE guide use plug-in
suppressors.
- The NIST guide says plug-in suppressors are "the easiest solution"
- The NIST guide says "One effective solution is to have the consumer
install" a multiport plug-in suppressor.
- A service panel suppressor would provide no protection in the IEEE
example, page 42.
- The IEEE guide says in one example "the only effective way of
protecting the equipment is to use a multiport [plug-in] protector".
- Martzloff says in a paper "One solution. illustrated in this paper, is
the insertion of a properly designed [multiport plug-in surge suppressor]".
- Dr. Mansoor supports multiport plug-in suppressors
- SquareD says "electronic equipment may need additional protection by
installing plug-in [suppressors] at the point of use".
- SquareD service panel suppressors do not list "each type of surge".


And the biggest fact:
westom has never provided a source that agrees with him that plug-in
suppressors do NOT work.

For real science read the IEEE and NIST surge guides. Both say plug-in
suppressors are effective.

isn't it Godwin's Law? (DAGS)

http://www.faqs.org/faqs/usenet/legends/godwin/

Godwin's Law is a natural law of Usenet named after Mike Godwin
(godwin@eff.org) concerning Usenet "discussions". It reads, according to
the Jargon File:

As a Usenet discussion grows longer, the probability of a comparison
involving Nazis or Hitler approaches one.


The obvious response is to call them on it, say "thread's over",
and declare victory. This is also one of the stupidest possible responses,
because it involves believing far too much in the power of a few rules that
don't say exactly what you wish they said anyway. The proper response to
an invocation is probably to simply followup with a message saying "Oh.
I'm a Nazi? Sure. Bye" and leave, and in most cases even that much of a
post is unnecessary.

But "westom" does post often WRT lightning protection.

A protector is only as effective as its earth ground. Which is why
the Cutler-Hammer protector - about $1 per protected appliance - is

bingo.

I'm still amused that people really believe bogus junk surge protector

OK, I can't find it on their website.

Read here. You say hundreds of thousands of Joules.
This one has 100KA at 840 Joules


The little bitty Tripplite laptop protector is over a 1000 Joules.

you really think so?

send one over to me, I'll post a video of me dumping 1kJ into to to see
what happens.

"People" - like the 6 electrical engineers that actually work at surge
protection?
Who say in a surge guide from the IEEE that plug-in suppressors are
effective?
And in a surge guide from the NIST that plug-in suppressors are effective?
Do you know of more reliable sources than the IEEE and NIST?

And you still haven't admitted that UL tests the devices it lists?

Still missing - your source that says plug-in suppressors are NOT
effective - just like westom.
And westom has been looking for years.

I can only conclude that you are a Nazi.

It is bud's job to constantly promote lies and myths. He is paid
to promote plug-in protectors. Lying is what promoters may do.
Where are those numeric specs? bud will never provide any.
He cannot claim protection that does not exist.

Where does that energy dissipate? bud cannot say. Otherwise
he must admit that plug-in protectors are profit centers – not
protection.

Uh... In the MOV?

I thought the MOV conducted above its breakdown voltage (generally around
300V), and the energy in the section of the AC waveform above that voltage
heated up the MOV.

Am I missing something?

Many years ago, PC and/or Byte (I forget which) used to test suppressors. If
they failed to provide suppression, I assume the mag would have said so.

You prove it. Your job is to promote plug-in protectors. You
cannot even post any spec numbers that define protection from each
type of surge. For good reason. To sell scam protectors, lying is
normal. You have been lying for years. Even your own citations show
damage to electronics because the protector is too close to appliances
and too far from earth ground.

Destructive surges are hundreds of thousands of joules. Where does
that energy dissipate? Bud says that energy just magically
disappears. Reality. Either that energy dissipates harmlessly in
earth - a 'whole house' protector connected within feet to earth
ground. Or that energy is hunting for earth destructively via
appliances.

Bud's citation Page 42 Figure 8 shows a surge earthed 8000 volts
destructively through a nearby TV. Why? The home was using a plug-in
protector promoted by Bud. The house did not earth via a 'whole
house' protector. Energy was inside the building. Therefore damage.

Where does all that energy dissipate? In hundreds of request, bud
never posts numeric specs that claim protection. Bud never posts those
numeric specs because no plug-in protector claims effective
protection. bud must deny to protect profit margins. A protector is
only as effective as its earth ground.

It is bud's job to constantly promote lies and myths. He is paid to
promote plug-in protectors. Lying is what promoters may do. Where
are those numeric specs? bud will never provide any. He cannot claim

Ohm's Law.
If the MOV conducts at a low resistance,the power it dissipates will be
minimal.
Thus,the surge energy gets dissipated in whatever ground it's shunted to.
