[QUOTE="Megaohm7, post: 190128, member: 393"] A Ze of 0.53 ohm on a pme is on the high side which would give you a pfc of 434 A. It's all down to what the circuit Zs's come out as and what the CPD's are and if the disconnection times can be met. The regs say a max of 0.35 ohm. You've enquired about this but the DNO say it's ok? . It seems to me that they don't want to be responsible for supplying a suitable earth. You might have to fit a rod/rods to provide a decent earth path. [/QUOTE]
