Default "chain" surge suppressers?

The IEEE Emerald book ("IEEE Recommended Practice for Powering and
Grounding Sensitive Electronic Equipment"), an IEEE standard, recognizes
plug-in suppressors as an effective protection device. This is the most
appropriate IEEE standard for protecting electronics.

Poor w_’s religious blinders prevent him from seeing anything that
conflicts with his religious belief in earthing.


The IEEE says more than Bud's half truths. Amazing how a salesman
will say anything to promote a product.

One type of surge typically causes no damage. This surge made
irrelevant by protection inside all appliances (and by a 'whole house'
protector). A surge that creates, at most, hundreds of volts.
Industry standards even in 1970 required electronics to withstand even
600 volts without damage. Some will install a plug-in protector for
this surge anyway.

A typically destructive surge arrives on any or all incoming wires -
seeking earth ground. Shunt some wires together with a plug-in
protector. That thousands of volts are shunted (clamped) on more or
all wires and still seeking earth ground. Surge current on any one or
all wires still must find a conductive path to earth. 8000 volt
damage to an adjacent TV resulted. Same surge made irrelevant – does
not overwhelm protection inside all appliances - when using only
‘whole house’ protector.

Earthing where a typically destructive surge would enter a building
- the service entrance – means tens of thousand of amps gets
harmlessly earthed either by a direct wire connection (cable TV,
satellite dish, TV antenna), or via a 'whole house' protector
(telephone, AC electric). A surge not inside the building does not
overwhelm protection inside appliances - does not cause surge damage.

Every responsible source says surge energy must be dissipated
harmlessly in earth. Well proven principles for the past 100 years
define a single point earth ground and short connection to that
electrode. Every Bud's citation even says what an effective
protector does: divert (clamp, connect, shunt) surge energy to earth.
But Bud is a salesman. He must twist anything - quote out of context
- post insults - say anything to promote obscenely profitable plug-in
protectors.

Bud will say anything to avoid what even his NIST citation says:
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.


How does surge energy just disappear? Bud says 'clamping to
nothing' will somehow stop, absorb, or make imaginary what even three
miles of sky could not stop. Wow. Bud knows magic. Professional
papers say that is impossible.

What Bud also ignores. A 'whole house' protector is secondary
protection. Homeowners are encouraged to inspect their primary
protection system:

If Bud admitted that, then Bud must admit what provides surge
protection: earth ground.

Bud again refused to provide a manufacturer spec that claims
protection. Why? No plug-in protector claims such protection. None.
Bud refuses to provide protection specs because those specs just don't
exist. Just another fact that Bud forgot to mention while so busy
posting insults.

OP asked for information on earthing. Easy. Many industry
professionals who install effective surge protection were cited. Bud
could not quote them. Bud claims surge protection happens without
earthing - 'clamping to nothing'. Professionals define what makes
surges irrelevant and what makes protectors more effective. Install
and connect protectors to a single point earth ground. Learn
principles of earthing from numerous industry professionals in a reply
to Caesar Romano - the OP. A protector is only as effective as its
earth ground; where surge energy must be dissipated. A fact that does
not require supporting insults.
