Re: Lightening strike ?
My house was built with Cat3 in the walls, running to a switch in the basement (why, yes, I am a bit of a nerd). I rapidly discovered that surplus commercial switches last for more than one near miss, because they generally incorporate ESD protection on the incoming lines, whilst consumer grade switches do not, and therefore give up the ghost the first time lightning strikes in the same state.
Electric garage door openers are also susceptible, due to the long wires to the button for manual opening and the safety sensors, which apparently run to unprotected inputs and act as excellent antennas for nearby lightning strikes.
