Hi
Saw a mates job the other day where the supply is three phase, however there was two earthing system at head there was tn c s and tn s. So there was separate earth clamped on supply wire to main earth terminal and a additional earth wire run which was connected to neutral of supply ?
Didn't think this is normal practice although dno have recently been to replace fuse ?
Then consumer was wired one earth in earth terminal and the other earth in neutral ?
