I can only recall one instance of a broken neutral causing a shock hazard in my time,over 30 yrs,that in a butchers shop in a village.
Regarding the 200 ohms value of an earth rod....it is ridiculous to mockingly quote this figure in conjunction with a TNCS where such a rod may be used to limit the danger of a lost N....the 200 ohms is intended for a TT system designed to operate at high Zs values....not a system designed to utilize a low value of Zs.
