come across this one been stuck on it for ages please help also please tell me how you came to the answer as I can guess the answer but I always like to know how. Here is the question thanks in advance. A periodic inspection on an existing single phase installation which has 12 circuits protected by BS3036 fuses shows its Ze measured at 0.09Ω. This is potentially dangerous because a. it shows no earthing arrangements b. the prospective fault current may be to high for the circuit protection c. the BS3036 fuses will not meet the disconnection times d. the prospective fault current maybe to low.
