    Accidental Electrical Contact

    .... but you have to remember that amperage is a product of voltage divided by resistance.Your body resistance does not change unless you are protected by rubber gloves,sleeves etc. ie protective gear. Unprotected contact with the normal 7200 volt distrubution lines[primary] could in theory...

    Accidental Electrical Contact

    The power company usually keeps the drop are pretty clear on their right of ways. Where the problem lies is when home owners plant a Christmas tree close to the house thinking it will remain small forever. Before you know it,it grows into the service drop while the roots undermine the...

    Accidental Electrical Contact

    Actually most triplex has cross link poly insulation [xlp] which is a tough as they come. Nothing though will prevent the stuff from getting chaffed through by rubbing against a tree building or what ever. The older single conductor service drops used some tar coated stuff called weather proof...

    Accidental Electrical Contact

    Another heads up.In the rare case of a double set of distrubution being used even a dead line can get you. They often run a double feeder ,three on one side of the cross arm and three on the other. Even if one side is deenergized the mutual induction from the other can charge those lines to a...

    Accidental Electrical Contact

    It only takes about a tenth of an amp across the heart for about 1 second to be fatal. Arm to arm you have about 10,000 ohms of resistance in your body with dry skin. Persperation,rain etc would lower this resistance so in theory it could get low enough for 120 volts to do you in. Actually more...

    Accidental Electrical Contact

    I've seen people do dumb things with service drops,especially on the farms.They might have an out building that needs power that has a tree in line with the source that they use for a pole. The dummys screw an insulater into the tree and run the wires through the canopy which in time shreds...

    Accidental Electrical Contact

    Usually aerial triplex remains in good shape for years.The exception is where it can come in contact to rub against a tree or something and wear out the insulation. It's only 240 volts but you still have to use caution. The cute one is where the secondary some how gets into the primary and...
