[QUOTE="Skipper, post: 559829, member: 38292"] Of course, as you leave the bonded area that is when the danger occurs, but, that can happen anyway in a T-N-CS situation ... the well known "cow shed" problem. It might make sense to bang some earth rods in as recommended by 411.4.2 anyway ... with earth electrodes at the customer premises to support the T-N-CS system rather than converting it to T-T ... whether it will be possible to get an earth impedance value within the limits of table 54 I don't know ... as I said, it is sand around here ... I suspect in summer when it dry as a nun's chuff may prove problematic! [/QUOTE]
