RIGHT! And that has NEVER been acceptable practice. NEC and other electrical codes REQUIRE that there be at least one driven rod for the electrical system ground, and a second if the impedance to earth of that rod is greater than 25 ohms. In most locations, that means two rods. In addition, NEC and other electrical codes require that the rod(s) be augmented by bonding the electrical system ground to all metallic plumbing, all building structure, and all other grounded objects. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
