Surge protection INSIDE the camper?

What can an RV'er purchase to protect against a nearby or direct lightning strike?

The concept was taught to all in elementary school. Lightning (and similar transients) seek earth ground.

Nothing will block that hunt. The solution was always as simple as Franklin demonstrated - it must be connected to earth.

For example, view a household TV cable or satellite dish wire. It must have a low impedance (ie less than 10 foot) hardwire connection to earth ground. That is best protection. A transient that hunts for earth need not enter a structure to find earth (destructively).

AC electric cannot connect direct to earth. So a protector must do what that hardwire does better. A protector at the pole make a low impedance earth ground connection. Then a transient is not inside hunting for earth destructively via camper appliances.

It was always that simple. But is too complicated for at least one who entertains his emotions due to insufficient reading abilities. If he knew this stuff, then he knew no protector does protection. He keeps posting as if the protector is all protection. He does not understand. A protector is only as effective as its earth ground. Unfortunately that is not what soundbytes and advertising teaches. So it is too scientific.

A lower impedance (ie shorter) connection to earth means less surge will find a path to earth via appliances. A higher impedance (greater separation between appliance and protector) does same. That means robust protection already inside appliances is not overwhelmed.

Disconnecting does little since these destructive transients (not just lightning) occur at almost any time. Nothing can disconnect fast enough since transients are microsecond events, occur without warning, and blow through anything that might try to block it (ie open switch, transformer).
