Re: Boy killed by lightning in our anchorage, what would you do?

Normal fuses provide no effective lightning protection. The little wire in the fuse vaporizes instantly and coats the inside of the glass with a thin layer of conductive metal.

Now if the potential from the strike is high enough, the now metal metal film resistor which used to be a fuse will explode from the pressure inside and when you open your little plastic fuse holder, you will find what looks like grey sand in there between the two little cups that were the ends of the fuse. Needless to say, what ever that fuse was supposed to protect is probably smoked too.
