believe that the signal lines are critical to protection. The whole
house suppression probably does not address this.
Any protector that does not make a short connection to earth ground
does what? Earthing that surge destructively elsewhere such as
through the adjacent appliance. Any protection that works at the
appliance is already inside the appliance. New standards mean that
signal lines must withstand even 15,000 volts without damage. Yes
that few volt signal line must also not be damaged by 2,000 and 15,000
volts
So we earth that surge before it even enters the building - does not
get near to signal lines.
Did damage exist? That says little about the protector and says
nothing about a plug-in protector. That damage says a surge was
permitted inside the building to maybe overwhelm protection inside
signal lines.
How does the telephone company with signal lines everywhere inside
their building not suffer computer damage? Every wire is properly
earthed either by a direct earthing connection or via a 'whole house'
type protector. Why is telephone service not down for four days every
year while they replace that computer? Why can that computer suffer
one hundred surges during every thunderstorm and not suffer damage?
They don't use grossly overpriced Panamax or Monster Cable products.
Instead they spend less money on more effective 'whole house' type
protectors and they enhance that single point earthing. How is the
protection made even better? They install even better earth grounds.
Did a surge enter on cable TV wire? Then how was that cable
earthed. Installing a Panamax on that cable TV wire is even not
recommended by the cable company for the same reasons that early 20th
Century Ham radio operators finally stopped surges. Will the Panamax
absorb surges?
The Panamax does not even claim to protect from type of surges that
typically cause electronics damage. Those who recommend that Panamax
routinely ignore that reality. Good reason why Panamax does not make
that claim. No dedicated earthing wire. No earth ground means no
effective protection.
Meanwhile, smoke detectors also were not routinely damaged during
surges. Is that because smoke detectors are connected to invisible
protectors? No. If something is undamaged with a Panamax proves
nothing since other appliances also are not damaged - and have no
Panamax. Damning is that the Panamax does not even claim to protect
from that type of surge.
