[QUOTE="westom, post: 1601904, member: 138367"] 4320 joules means it absorbs 1440 joules and not more than 2880 joules. How does that protect from destructive surges that are hundreds of thousands of joules? Why post numbers that you ignore? If a surge is 100,000+ joules, then how does a protector (at $60 per appliance) at only 2880 joules absorb a surge that is 100,000 joules? Read and comprehend every number in that sentence. Proven solution costs about $1 per protected appliance. Why ignore that number? $1 for a proven soution verses $60 for a near zero solution? Because many only believe advertising and hearsay rather than science. Even Nigerian princes profit from consumers who ignore what the numbers say. Once a surge current is inside a building, then (for all practical reasons) no protection exists. For a 4320 joules protector to be effective, that surge current must remain outside a building. If the current remains outside, then a 4320 joule protector is not needed. Catch 22. Why waste so much money on a protector that is only useful when it is not needed? Protection is about earthing a surge. A 4320 joule protector absorbing (at most) 2880 joules has no earth connection. Why would earthing a Mac provide protection? Earthing a Mac would only make that Mac a best and destructive path to earth. Please reread previous posts that explained this. Again, at least three rereads. Why would a 4320 joules protector (that can only absorb up to 2880 joules) make irrelevant a hundreds of thousands of joule surge? Do not read further. Answer that question. Facilities that cannot have damage do not spend tens of times more money on a near zero, adjacent (magic box) 4320 joule solution. Why then would you? Please read the numbers. 4320 joules is near zero protection.; [/QUOTE]
