I’ve been thinking about buying a power board with built in surge protection. I was looking at getting this Belkin 6-Outlet Surge Protector http://www.umart.com.au/pro/products_listnew.phtml?id=10&id2=57&bid=2&sid=22414 My question is, is 1940 Joules of protection enough? 1940 Joules doesn’t sound like much. I did a bit of research on good old Wikipedia and found lightning can be in the order of hundreds of mega joules. In your typical lightning strike that blows up computers is most of the energy dissipated in the powerlines before it gets to your house? When claiming on the warranty how can they even tell how big the strike was? Obviously if it was a melted lump of plastic it the strike would have exceeded the units rating but are they likely to say that any damage caused to computer components was caused by a strike in excess of the surge protectors rating?
