Some may be in severe locations where all that additional work would be necessary. Because damage from direct lightning strikes is directly traceable to human failure. Routine is to have direct lightning strikes without damage. But only if an electrical current to earth is via non-destructive...

Your problems stem from not yet understanding relevant electrical concepts. For example, connect a 200 watt transmitter to a long wire antenna. Touch one part to feel no voltage. Touch another part of the same wire to be shocked by maybe over 100 volts. Why two completely different voltages...

An adjacent protector or UPS only claims to protect from a type of surge made irrelevant by protection already inside all appliances. Destructive surges cannot be blocked or absorb inside a building. Either a potentially destructive surge is connected to earth BEFORE entering the building (ie a...

Quite simple. Destructive surges are hundreds of thousands of joules. The only UPS that addresses your problem will state in its spec numbers how many hundreds of thousands of joules it can absorb. Be extremely cautious. Many will recommend a UPS only rated at hundreds of joules. Near zero...

Answer starts with what was taught in elementary school science. Lightning is an electrical current the flows from the cloud, through air, (through a wooden church steeple,) to earthborne charges miles away. Wood is an electrical conductor. But not a very good conductor. So it creates a voltage...

First, damage occurs because a current found a path incoming and outgoing through electronics. Bot paths must exist to have damage. A lightning strike to AC wires far down the street is a direct incoming path to all appliances. Which are damaged? Which also made the best outgoing path to...
