[QUOTE="Sidewinder, post: 444387, member: 9512"] Not necessarily john, two separated rods are better than one single, especially if they are correctly interlinked. Think local PME without all the risks of diverted N current... They become an earth nest, a good concept. I have seen one rod low enough to operate a B6, by the time you add bonding, probably a B16, add another rod and some more inadvertent earth paths, and you could be below 1 Ohm?.. RCD's are rubbish devices though, that I do agree with. [/QUOTE]
