[QUOTE="Phoenix, post: 220747, member: 8133"] It wasn't fault currents that was the issue, if you think about it you'd still have that issue with TT, even more so, the buried metalwork being a better earth than the electrode More so, it was the currents that flow when there isn't a fault... the tanks and the ground being a parralel path to the supply neutral conductor and currents flowing in normal operation., obviously not as good a path, but still good enough that some of the neutral current would return this way, most installations this isn't an issue, but must don't have anywhere near as many voltile hydrocarbons to worry about! Of course the dropped neutral chesnut is a worry as well! [/QUOTE]
