As far as lightning protection, they'll do part of that, up to the

In professional papers, tiering is not about protectors.

From surge expert Martzloff:
"Whole house protection consists of a protective device at the service
entrance complemented by [plug-in surge suppressors] for sensitive
appliances [electronic equipment] within the house."
Kinda sounds like tiering to me.

Protectors that do not even claim protection in their numeric specs
(ie that Belkin)

Complete nonsense.

will not discuss earthing.

Because anyone with minimal intelligence can read in the IEEE guide that
plug-in suppressors do not work primarily by earthing.

They hope you ‘assume’ a
protector magically makes energy disappear.

Only magic if your religious blinders prevent you from understanding how
suppressors work.

The NIST (US government
research agency) citation provided by Bud is quite blunt about what an
effective protector must do:

Ho-hum. w just repeats the same distortions. Repeating:
What does the NIST guide really say about plug-in suppressors?
They are "the easiest solution".
And "one effective solution is to have the consumer install" a multiport
plug-in suppressor.

Bud’s IEEE citation – page 42 Figure 8 – shows where that
energy dissipates:

The lie repeated.

Responsible companies including General Electric, Leviton, Intermatic,
Siemens, Square D, and even the Cutler-Hammer solution that sells in
Lowes and Home Depot for less than $50.

Ho hum - 3rd repetition. Repeating:
Being responsible companies, all these manufacturers (except SquareD)
sell includes plug-in suppressors. And the $50 devices do not meet w's
minimum specs.

Plug-
in protectors do not – are not part of a ‘tiered’ solution.

Martzloff says they a
"Whole house protection consists of a protective device at the service
entrance complemented by [plug-in surge suppressors] for sensitive
[electronic equipment] within the house."

Each protection layer is defined by what provides protection – the
single point earth ground.

And the required religious mantra.
Still not explained - why aren't airplanes crashing daily when they get
hit by lightning (or do they drag an earthing chain)?

Still no link to another lunatic that agrees that plug-in suppressors
are NOT effective.

Still never answered - 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, pdf 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 do your favorite manufacturers make plug-in suppressors?
- Why does favorite manufacturer SquareD say (for their service panel
suppressor) "electronic equipment may need additional protection by
installing plug-in [suppressors] at the point of use"?

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