would totally agree.under certain condition and under certain applications of the 17th edition. to be fair i wouldnt be able to sleep at night if i left a socket circuit with a Zs of 1660 ohms say. what happens if the rcd fails? spesh if its a protek!! lol
ive been following it shakey, thinking to myself will i ever have that much knowledge haha :^Omight be worth you reading the 'max Zs' thread, this is being discussed in depth there
absolutely correct GILPardon me for being wrong (I'm sure Shakey will hit me if I am!) but generally speaking, high Ze values are likely to happen mostly with TT systems. If you have TN or TNCS then you should (hopefully) have low Ze to start with, and therefore compliance with the maximum Zs of MCB's should be acheivable.
