The neutral wire failed inside a transformer. Building's earth ground had been compromised. But since the lights still worked, the homeowner did nothing. To transport electricity back to the defective transformer, the house use a natural gas line. Fortunately no one was home when gas line gaskets finally failed at the meter; the house exploded. If that doesn't souind like an urban myth.... Many say lights work just fine. Therefore, don't worry. Be happy. Even the military calls for inspections of these grounding connections every 5 years or sooner. A homeowner must take responsibility for his ground connections. The consequences sometimes can be catastrophic as demonstrated by multiple examples. running dogg wrote: ... My grandfather once lived in a rural area where the power poles didn't have grounds. When lightning hit the pole, foot long flames came out of the sockets. It ruined everything electrical, and he had to rewire his house several times, but it didn't burn down. |

If that doesn't souind like an urban myth.... Yeah, it does to me too. I doubt that electricity would be transported back to a transformer via natural gas line. Natural gas is awfully volatile. Also, if the neutral wire INSIDE one of those huge oil filled transformers up on a pole failed, how would the homeowner know, much less act? I suppose that an arcing transformer would cause horrible SW interference (not sure about MW) but most people don't have SW radios. In that case only a local SWL or ham would notice. All new construction around here requires 400 amp household grounds built into the foundation. Typically the special ground rod is simply stuck into the concrete. I think it should be actually buried in the earth, but apparently that's not necessary. Fortunately lightning storms are rare here, and when they DO happen they're rarely on the scale seen in Florida. (I never understood why people think Florida is paradise; they have some NASTY weather there and some really, really bad urban ghettoes.) ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

Everything in front of the polyphaser was destroyed. Everything in back of it was fine. I'm sure a strike could have done more damage - but it's not hopeless. In my case, a strike would need to follow over 300 feet of underground coax to get to the house. Reading your house insurance policy contract is a good idea, in case there is something in there. There are differences, but even though they're insured with different companies in different states, the insurance contracts I've read for homes in CT, FL and NJ look to be based on the same boiler plate form. Insurance companies aren't likely to deny a claim if you can show you made even a minimal good faith effort to have a safe system. The courts would rule against them unless they could point to a specific provision in your policy allowing them to deny coverage. The company sets the terms of the contract, so anything in doubt will be decided in your favor. On the other hand, if an insurance company inspected your house and saw an antenna they might decide they don't want to insure you - but they'd need to give you time to correct the problem - and you'd have some time to try reasoning with them if you really have made (or are willing to make) an effort to make sure the system is safe. But frankly, I doubt antennas are on their minds. A friend with a serious antenna farm got a letter threatening to drop him if he didn't put a second railing on his back steps. Hard to imagine they could see the steps without noticing the antennas. Your concern someone could be tossed in jail for an unintentional building code violation is incredible. I'd have to concur. Unless you were so criminally negligent and put others at risk, such as tenants, I see no reason you'd be prosecuted. Also, insurance would pay your claim but then drop you. And some won't pay... not necessarily for a lightening strike but for an auto accident. A word to the wise.. don't insure with AAA. Trust me. My sympathies. I actually appreciate that as it's been a real pain in the neck (no pun intended) for the last (almost two years). But what the heck, it'll only take about $30,000 to fix. Best of luck with that.

The investigator was a personal friend who we stumbled upon
as he was returning from the exploded house. He immediately explained what had happened - the broken neutral wire inside transformer and no building earth ground. It was one of those, "Of course. I never realized that could happen." moments. As it would when one is familiar with 'how and why' buildings and utilities are earthed. Another event created by a missing earth ground was continuous ringing of telephones in some adjacent homes. The offending home was not properly earthed. That house used other utility wires as a neutral wire. The emergency response guy borrowed infrared goggles from the fire department to follow a cable TV wire. Wire was so hot that he could follow that wire behind walls with infrared goggles. Basic knowledge of how utilities connect make it obvious that electricity could use gas lines (or other conductive materials) as a neutral return - given a failure in the right spot AND no building earth ground. Feel all you want. But earth ground is essential for human safety as well as for other reasons. Facts remain electrical. Feeling has no place here. Either one can say specifically why that gas line was not used as a neutral return - or one does not have sufficient knowledge to respond. Feelings are not sufficient. A doubting response must be able to say why - using fundamental electrical principles. Anything less would be junk science reasoning. Homeowners have enough in these two discussions to appreciate why earth ground is essential to human safety AND why (and how) that earth ground should be enhanced to provide transistor safety.
