Why are we still dragging out a two month old article? Let it go Speedskater. The OP has moved on. As for that article, the writer was way off on what a "Bootlegged" ground is at the beginning of the article. They did finally cover it in paragraph 7, which is usually when you lose the majority of readers. The majority of articles on ECMWeb are written for the experts in the field, but laid out in layman terms, that the everyday person is still not going to understand what the writer is talking about.
As for testing for Bootlegged grounds or other power wiring faults, it takes someone that knows what they are looking for and knowing how to fix it, not for the average person to fix these problems. That is why those like myself and other professional sparky's tell people to leave it to those who are licensed, and know the rules, to handle these situations, along with making sure a panel is properly grounded to Earth Ground. Same goes with incoming CATV, Telecommunication that should be grounded to the Ground rod, or Cold Water pipe if the area the person is in, allows for Cold Water bonding for ground protection, not by connection a wire to the hose bib outside, or a cold water pipe in the house thinking that it is a continuous ground out to the curb, or even worse, when the contractor or company employee for your CATV or Satellite company places a strap on the casing of the meter pan, without verifying that it has a proper ground to the ground rod.Edited by gregzoll - 8/16/13 at 6:24pm
