1  Deploy REW of appropriate grade

2  Arrange power suspension

3  PITC Work for Distribution Circuit

3.1  Visual inspection
3.2  Continuity test for protective conductors
3.3  Continuity test for ring final circuit conductors
3.4  Insulation resistance test
3.5  Polarity test
3.6  Earth electrode resistance test
3.7  Earth fault loop impedance test
3.8  Functional test for protective devices

4  PITC Work for Low Voltage Switchboard

4.1  Isolation and proved dead
4.2  Cleaning
4.3  Visual inspection
4.4  Contact resistance test
4.5  Insulation resistance test
4.6  Secondary injection test
4.7  Functional test for protective devices
4.8  Check indication devices

5  Record all inspection and testing results

6  Resume power

7  Issue periodic test certificate and testing records

8  Submit periodic test certificate and testing records for EMSD’s endorsement
