Surge protectors are like a hanky over your mouth in a dusty environment. They will clean off static charge pulses into the thousands of volts, but of no consequential duration. They do this (cheaply) with a choke (coil of wire tuned to non 60 cycle higher frequencies, and capacitors that can suck up voltage temporarily, then feed it to a resistor. THey are only good for casual static buildup from shoes on wool carpet and nylon jackets on wool sweater type issues. UPS (uninteruptable Power Supplies) are a step up in the sense that they consist of a 1:1 isolation transformer that separates the power out from the power in. The power is then rectified and filtered to DC charging a storage device (usually a battery) the battery output is then inverted into regulated AC for use by the device plugged into it. They are much less prone to passing destructive spikes, and will work even with 30 volts on the input at wild frequency variation. The more over 250$ you spend the better these perform. Some cost thousands and can handle a room full of equipment. They are also capable of running the equipment for a set time while it shuts down (usually because the equipment is digitally interlinked (smart) so it shuts down when the power is interrupted. Though better, these are not lightning protection. Remote disconnected backups are your only protection. USB HDD with an unplugged status works well One terabyte for about 100 bucks at sams club. The best policy is unplugging and moving all wires 12 inches from the outlets and cable jacks/modems, A pain, but what is the value of the content you have on the equipment. Jim

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
