Default Surge / Ground / Lightning

The big problem with the whole bud vs. w_ debate is they aren't debating the
same thing. Each is talking about a subset of the whole field, and mostly
are not overlapping in what they talk about.


Bud claims plug-in protectors provide a complete protection system -
can protect from all types of surges. A plug-in protector only
protects from surges that rarely damage appliances. As demonstrated
repeatedly in other posts, plug-in protectors have even earthed a
typically destructive type of surge through adjacent appliances. A
problem alleviated by earthing a 'whole house' protector.

So that plug-in protectors do not compromise protection inside all
appliances, the typically destructive surge must be earthed BEFORE
entering a building. That solution is used everywhere professionals
install protection. Everywhere. Bud also denies this.

If a destructive type surge is properly earthed, then one can spend
money on plug-in protectors to also protect from a typically non-
destructive surge. This is called "complete protection". However
better facilities make that whole house' protector even more effective
by enhancing earth ground. Where is money better spent?

If not using a 'whole house' protector, well, even 'scary pictures'
created by typically undersized protectors now creates a hazard.

Bud disputes this. Bud says if all wires connect to the same
protector, then surge energy somehow disappears. Obviously not true.
That surge energy must be dissipated harmlessly into earth. Just
another reason why plug-in protectors create problems when a 'whole
house' protector and (more important) proper earthing is not
installed.

Others claim a plug-in protector will stop or magically absorb
surges. Obviously no protector stops lightning. Obviously (from so
many professional citations) lightning damage is routinely eliminated
by diverting typically destructive surges to earth ground "where it
will do no harm".

Yes, plug-in protectors do have limited protective functions. But
the discussion is about the type of surge that typically does surge
damage – that finds earth ground destructively through appliances.
Any protector located too close to appliances and too far from single
point ground cannot protect from that type of surge. So Bud invents
this magic plug-in protector that somehow makes surge energy disappear
and that, by itself, is a complete protection system.

Bud pretends that typically destructive surges don’t seek earth
ground. Even plug-in protectors need that properly earthed 'whole
house' protector so that plug-in protectors do not contribute to
adjacent appliance damage. Only then can a plug-in protector do what
it is designed to do - protect from a type of surge that typically
does not cause damage.
