"w_tom" wrote in message ... [snip] If refrigerators and air conditioners were creating destructive surges, then all would be trooping daily to hardware stores to replace damaged dimmer switches, electronic timers switches, X-10 remote controllers, and touch on-off lamps. Surges created by refrigerators, et al are urban myth because you don't replace those other appliances daily. Well, who'd have figured? Here's a variation on that urban legand. Cut the current to an inductive load such as a motor, and it makes a surge of voltage! I'm so glad the clued-in know better. Furthermore if refrigerators, et al created those surges, then surge protector must be installed in that surge creating appliance - not on every other appliance. As all the Clueminati know, that's a big, big if. If refrigerators created those voltages in excess of 330 volts (as listed on surge protector boxes), then we must remove those appliances as a threat to human life. We don't remove those appliances because they don't create 'urban myth' surges. E-mail is certainly more responsible than appliances for the urban myth surges. We have the case down cold. MOVs have limited life expectancy as defined by joules. If refrigerators and air conditioners were creating destructive surges, then those plug-in surge protectors would be degraded in weeks or months without any indication of failure. What good is a $50 surge protector that must be replaced every month? Ineffective. I ruined my surge supressor by reading posts on AFU. HowStuffWorks on surge protectors has numerous technical errors. It begins accurately, but then makes serious errors. It preaches what plug-in surge protectors promote rather than the principles of surge protection proven in the 1930s. It preaches concept that if accurate, negate any need for 'whole house' type protectors. The author probably did not have sufficient knowledge to see through half truths promoted by his information source - plug-in protector manufacturers. Therefore HowStuffWorks is riddled with errors and misrepresentations. That's right. Don't trust advertising literature! Because plug-in surge protectors don't claim protection from direct lightning strikes, then instead HowStuffWorks claims most surge damage comes from refrigerators, et al. Demonstrated is that such surges don't typically exist. In reality, lightning is a most common source of surge damage - in direct contradiction to plug-in manufacturer claims and to text in HowStuffWorks. Surges occur typically once every eight years. Surges every eight years? Then I gotta ask Art Bell just what's ruining those surge supressors! HowStuffWorks provides so much wrong information that it should be outrightly avoided and should not be recommended - except to demonstrate how to promote urban myths. Example: since plug-in surge protectors don't claim protection from lightning, then an outright lie is declared: You know it, d00d!! Here's what the liar Wendell H. Laidley, President, Zero Surge Inc., wrote: "Myth #10. NOTHING CAN STOP LIGHTNING. While this simple statement is true in absolute terms" This is from: http://www.totse.com/en/technology/c...ogy/surge.html Well, he goes on to claim that his products offer better partial protection from induced lightning surges than the partial protection offered by the supressors offered by other companies. Well, I say protection and partial protection aren't exactly the same thing. I wish I could get one of those surge protectors the Clueminati use. Those supressors must throw the lightning bolts back into the clouds, where they belong. Actually lightning only overpowers the undersized surge protector sold by plug-in manufacturers. Visit real surge protector manufacturers to learn why man has shunted direct strikes without damage since before WWII. Man has shunted direct strikes without damage since before WWI. Man has shunted direct strikes without damage since before the Spanish-American war. Man has shunted direct strikes without damage since before the Civil War. Man has shunted direct strikes without damage since before the Mexican American war. Man has shunted direct strikes without damage since before the War of 1812. Man has shunted direct strikes without damage since before the Revolution. Man has shunted direct strikes without damage since Ben "Freemason" Franklin figured it out. But why? Why shunt protection when series protection is claimed to be better? And why is such manly knowledge parceled out by the manufacturers of real surge protectors? Must be a Clueminati thing. 'Whole house' protectors are properly sized to avoid lightning damage. HowStuffWorks is biased towards grossly overpriced, undersized, ineffective, plug-in surge protectors - that cannot protect from the most common source of surge damage - the common mode transient. Yes! Finally we get to the all damaging common mode transient! There are still morons who discount the dangers!! To quote from the idiotic, inane fools at the ZeroSurge website: "We can readily see the common mode surge risk is not just low, it is nonexistent." This is from: http://www.zerosurge.com/HTML/mode2.html Thank goodness the unnamed makers of Real Surge Protectors who know what the hell they are talking about. More errors are about those indicator lamps. The OK lamp does not report that a surge protector is functional. Remove all MOVs and the indicator lamp would still claim the surge protector is OK as demonstrated in these scary pictures: http://www.zerosurge.com/truth.htm Did Art Bell clip those out? HowStuffWorks provides so much wrong information that it should be avoided. Only a grossly undersized surge protector will fail catastrophically. Only catastrophic type of failures can be reported by the light. Properly sized surge protectors only degrade. A degraded surge protector will still indicate OK on that lamp. Indicator can report that a surge protector has grossly failed (because it was undersized) BUT cannot report that a surge protector is good. Scary pictures demonstrate this problem by removing all MOVs - and still the surge protector indicator lamp says it is OK: http://www.zerosurge.com/truth.htm HowStuffWorks has outrightly mislead about that indicator lamp since the English major did not really understand how that light works. They forget to mention that phone lines have been installed with 'whole house' surge protector for decades. Yes. The telco provides a 'whole house' protector on household phone lines - for FREE! Again propaganda from ineffective plug-in manufacturers that routinely forgets to mention, for example, that surge protection is earth ground. An effective surge protector only connects to surge protection - earth ground. A surge protector is not surge protection - as they would have everyone believe to sell their overpriced product. The HowStuffWorks article ignores the most critical component in all surge protection 'systems' - central earth ground. However *real* surge protector manufacturers discuss earthing extensively: http://www.polyphaser.com/ppc_technical.asp Why does HowStuffWork ignore fundamentals of surge protection? Why does it completely ignore the most critical component of a surge protection 'system'? Urban myths are common even though those fundamentals have been proven since the 1930s. Unfortunately, HowStuffWorks mixes accurate information with urban myths. For example, we are not replacing damaged dimmer switches and other appliances daily. Therefore refrigerator and air conditioner are not creating those damaging surges claimed by HowStuffWorks. Here's another related urban myth for 'ya. Underwriter's Labs requires electrical devices to withstand these surges or they don't get approved! The HowStuffWorks surge protectors article is chock full of such misrepresentations. So full of errors and misrepresentations as to best avoid. Fundamental to surge protection and not mentioned by HowStuffWorks - a surge protector is only as effective as its earth ground. HowStuffWorks does not even mention the most critical component in any surge protection 'system' - single point earth ground - because it is not discussing effective surge protectors. What can you expect? They hardly mention the miracle of shortwave radio!! Maybe you could write some clear articles about grounding and SW radio. Show those English majors a thing or two!
