How many people are aware of the "cable knot as lightning protector" theory?
This post on LinkedIn recommends installers be in the habit of tying knots in cables for the purpose of lighting surge prevention.
I've heard this stated many times over the years, and many arguments about why it does, or doesn't, work for an actual lightning strike.
How many people here tie knots in power cables or any kind of low voltage cable? Has anyone ever see a cable that was damaged at/near a knot, but otherwise protected the equipment connected?
I'm skeptical this would do anything useful, if that were the case it would seem that electronics companies would use this technique all the time as cheap insurance against equipment damage and return/repair issues.
