### sec.22 Locating and dealing with electrical faults A coal mine must have a standard operating procedure for re-energising an electrical circuit at the mine that has been switched off by a circuit protection device. A person may use electrical energy, other than electrical energy generated from appropriately designed test instruments, for locating, isolating or clearing only the following electrical faults— an overload of an electric motor; an earth leakage trip associated with an impedance earth circuit; a 30mA earth leakage trip; an earth continuity trip.
