Im in need of a circuit diagram of the earth fault loop impedance path from e.g. a faulty kettle for a TN-S earthing system and TN-C-S. i have done a TT system but not sure how to show on paper how the earths connect together using correct symbols. for example on a tn-s system how do i show how the earthing conductor connects onto the lead sheath?
any thoughts or pictures would be a great help
