Q The earth fault loop impedance for three of the final circuits were
L1.1 0.61 ohms
L1.2 0.42 ohms
L2.3 0.21 ohms
determine, showing all calculations, whether these circuits comply with BS7671
the scenario I have stats measured Ze 0.08 all at 20c
do I have to do something with 80% 0.08 rule of thumb ??
