We have visited a large site, where the on-site electrical team have advise us that the supply is a TNC-S, but they have a global earthing system.
What is a global earthing system?
What size earthing conductor ?
What size bonding conductor?
As 1 TX supplies many building from one main panel, what should the earthing and bonding conductor be? Each building as a earthing cable which goes to a rod i Believe?
Looking for clarification on this.
