Re: Re: running cat5e outside

["Ian Davidson" <ian@xxxxxxx>]

I was hit by lightning at the last house, it struck an aerial at the front
of the house and came down the metal pole, it then branched, some coming
down the aerial feeder the main part jumping into the alarm bell box and
down the alarm cable. As it entered the house it jumped onto every thing
metal, phone cables, the metalwork in the corners of the plastered walls
etc
etc. Not a single piece of equipment that plugged into the mains survived !

There are many arguments about lightning i.e.

If something is not earthed the lightning will not be attracted to it as
much in the first place, but if it does strike it will find a way to earth
as can be seen above !

If something is earthed it will attract the lightning more but if earthed
well enough should allow the strike to be conducted directly to earth.

I'll let you make your own mind up.
