Default Does as GFCI give you some surge protection?

Joseph - earthing IS the protection. No way around reality. So
important that earthing (and not a protector) is why munition igloos
are directly struck - and munitions do not explode. Earthing is what
makes telephone switching stations - connected to overhead wires -
operate during every thunderstorm without damage. In each case, plug-
in protectors are not used AND may even contribute to transistor
damage.

Even the Air Force defines what is necessary for protection:
US Air Force Instruction 32-1065 1 Oct 1998
Grounding Systems
15. Surge Protection.
15.1. Entering or exiting metallic power, intrusion detection,
communication antenna, and instrumentation lines must have
surge protection sized for lightning surges to reduce transient
voltages to a harmless level. Install the surge protection as
soon as practical where the conductor enters the interior of
the facility. Devices commonly used for this include metal
oxide varistors, gas tube arresters, and transzorbs. The lines
must enter the facility in shielded cables or metallic conduits
run underground for at least 15.24 meters (50 feet) from the
facility.


Where are protectors located? As soon as practical where conductor
enters the facility. That is a 'whole house' protector - not a
useless plug-in device. Where does the Air Force require plug-in
protectors? Never. Air Force does what telcos also do to not have
surge damage. Install protectors with shot connection to earth.

What happens when a plug-in protector does not disconnect fast
enough? Why must the protector circuit disconnect so fast and leave
the appliance connected to AC mains? What happens when it does not
abandon appliance protection fast enough?

Proven solutions come from manufacturers that you know as
responsible. GE, Square D, Intermatic, Leviton, Cutler-Hammer, and
Siemens. Why then would you recommend a sold by manufacturers such as
Monster Cable? Why would you recommend a plug-in protector that will
not even claim to provide such protection in spec sheets? Even Bud's
own citations describe what is necessary for protection - earthing.
But even admits his companies protectors do not earth. So where is
the protection?

Either a surge is shunted (clamped, diverted) or it is absorbed.
That's it. Two choices. Joe - you tell me. How does a plug-in
protector absorb what 3 miles of sky could not? No wonder Bud's
citations show plug-in protector destroying a TV at 8000 volts. But
then engineers traced same destruction previously. I personally traced
and replaced every IC in the surge path to make the network working
again. Bud's plug-in protector earthed a surge, destructively,
through computers. Plug-in protector can't divert to what it does
not have - earthing. Tell us how Bud's 'magic box' will stop or
absorb what three miles of sky could not? It cannot shunt (clamp) to
earth. So how does it absorb surges?

Do you really know this stuff? Good. Then post that 'whole
picture' I somehow never learned over so many decades. Don't make
unsupported claims as Bud does. If you have another 'whole picture',
then post it.

Meanwhile what did Orange County FL do to fix repeated surge damage
to emergency response facilities? Did they buy plug-in protectors? Of
course not. More damage was not acceptable. Orange County fixed the
protection; that means earthing:

No earth ground means no effective protection. How many whole
pictures do you need? A reality denied to sell plug-in devices such
as Monster Cable's $100+ products (along with their $60 wire specially
designed for speakers).
