[QUOTE="Art Welter, post: 100803, member: 52"] Re: lightning protection for powered speakers For sure! Recently assessed lighting damage at friend's house. He has a lightning rod, but the lighting decided not to use it, took out two phones (phone lines were OK) a internet receiver and the router and one computer hard wired to it. A GFCI outlet outside near where they saw the lightning flash was the likely point of entry, it showed scorch marks between the neutral & hot and the foam lined cover. The GFCI was dead, and the motion sensor light nearby was stuck in the "on" position. Two out of the 9 the light fixtures on his porch, all on the same circuit (through a dimmer that was stuck full on, but still worked as a switch) still worked. I expected to find burnt bulbs or a burnt open wire, but instead found one wire nut connection (out of nine) had stopped passing current. After loosening it and putting it together it worked fine, there was no visual indication whatsoever why it would not pass AC before being opened. He found a few days later his deep well pump also was dead... [/QUOTE]
