I see you still throw that Orange county Florida garbage even though they found that the earth connection was bad.
It was explained multiple times. A simple concept. But he intentionally ignores it. Otherwise he would have to apologize for all his insults.
'Line to line' and 'line to neutral' transients are made irrelevant by protection already inside appliances. They have names such as transverse. Typically cause no damage. Adjacent protectors are designed to protect from irrelevant transients. Transients made irrelevant by what is already inside appliances.
Another type of transient approaches an appliance on any or all AC wires ... in the same direction. This has names such as longitudinal. This current may create no voltage across a 'line to line' protector. While also creating thousands of destructive volts inside an adjacent appliance. That type transient must be earthed BEFORE entering a building. Once permitted inside, it uses appliances destructively as a connection to earth. No adjacent protector will discuss it or protects from it. Some naive consumers will then make excused rather than learn why he made damage easier using an adjacent protector.
If a destructive surge is approaching on all AC wires, then an adjacent protector sees no voltage while that current is blowing destructively through the appliance. Sometimes that destructive transient approaches only on one wire. For example, the hot (black) wire may be at 6000 volts. What does that adjacent protector do? Leaves that 6000 volts incoming on the hot wire. And puts maybe puts 5600 volts on the green and white wires (assuming a 400 volt 'line to ground' and 'line to neutral' protector).
Now that current has three wires to hunt for earth destructively. One wire at 6000 volts. Other two at 5600 volts. That protector only sees a 400 volt transient. Where is protection? That adjacent protector is doing exactly what the manufacturer same it would do.
If he knew how a protector worked, then he posted technical facts. He never does. Instead he harps about the obviously irrelevant 'line to line' protector. Then denies case studies from Florida and a Nebraska radio station because he does not understand them. Education by advertising makes basic science difficult.
Protection is never about a protector. Protection is always about the earth ground.
How does that adjacent protector (that claims to absorb hundreds of joules) somehow stop or block a surge that is hundreds of thousands of joules? It doesn't. It cannot and does not have an earthing connection. It does give typically destructive transients even more paths to blow through adjacent appliances. Fortunately the only protection from typically destructive transients is already inside electronics. But only if that transient is tiny.
When damage happens, the naive proclaim nothing can protect from lightning. It is called denial. The other and well proven solution routinely does that protection. But only if properly earthed - as even discussed by Nebraska and Florida case studies.
Why is an insurance (warranty) bogus? Why does it have so many exemptions? An adjacent protector is often so grossly undersized that even it needs protection only possible by earthing one 'whole house' protector. Best is to let naive consumer believe the bogus warranty claims.
Facilities that can never have damage only earth 'whole house' protectors. A telco's CO suffers about 100 surges per storm without damage. Need do nothing for irrelevant 'line to line' and 'line to neutral' since even those are made irrelevant by earthing a 'whole house' protector. Which costs many times less money.
The fewer and informed know about transverse and longitudinal currents. Know why earthing and a 'whole house protector is necessary to even protect grossly undersized plug-in protectors. Where does hundreds of thousands of joules dissipate? Only the informed both ask and answer that question. As did case studies in Florida and Nebraska.
