Hi all.
Could someone with better understanding help clear this up for me please;
In the Regs (544) there appears to be no value of resistance for the above and also states that if copper, need not exceed csa of 25mm2.
In GN3 it talks about using a value of 0.05 ohms for verification of bonding conductors that can't be seen.
If I had 100m of 10mm2 Earth visible for its entire length am I correct it would comply(assuming no other factors apply), and that if not visible, an estimated reading in the area of 0.18 ohms would mean that it wouldn't comply as per GN3?
Above is just example to show I've made a bit of an effort!!
Thanks in advance
