View its specifications. Where does it list each type of surge and protection from that surge? It does not. Many claim it will absorb surges. Ok. It is 885 joules. That means 295 joules and never more than 590 joules absorb a surge that is hundreds of thousands of joules. It provides nothing to absorb all that energy. So where does a surge get absorbed? Either inside that protector (destructively), or maybe inside adjacent appliances. A protector is only as effective as its earth ground (also applies to the UPS). Either a surge is diverted short to and absorb harmlessly in earth. Or that surge is inside the building looking for earth ground destructively via electronics. Stop looking for a magic box. There is none. Either a surge is harmlessly connected to earth and does not enter the building. Or the surge dissipated its energy inside the building. You are having an electrician come. He can install protector for everything in the house at the breaker box and upgrade what provides protection - breaker box earthing. You were taught this in elementary school science. Lightning found a more conductive path to earth - wooden church steeples. To protect steeples, Franklin simple diverted lightning to earth via a lightning rod. Again, what provided the protection? Earth ground. Did the lightning rod magically block or absorb that surge? Of course not. Protection is always about diverting surges to not enter a building. Even wood and concrete are conductors. Surge protection means an earthing connection is more conductive than anything else. A better protector connects short to earth - ie 'less than 10 feet'. No sharp wire bends, No splices, etc. Where does that Belkin device claim protection in its numeric specs? 1) It has no dedicated connection to earth. 2) Manufacturer avoids all discussion about earthing. Two factors that identify ineffective protectors. Your Belkin unit meets both conditions; is that ineffective. Claims to protect from a surge that is typically not destructive. No earth ground means no effective protection. What makes Franklin's lightning rod so effective? Earthing - where surge energy gets absorbed so as to not enter the building. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed Low End Mac's G3-5 List, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
