Students training aid for testing continuity of the CPC and polarity of a simple 1 way lighting circuit. Full demonstration using a MFT Megger tester set on the ohms scale, linking the line and CPC of the circuit under test and then testing at every point in the radial lighting circuit. Of all the reading we take in ohms we record the highest reading in our test paperwork under the box heading R1 + R2 continuity of CPC. We also complete the polarity test and leave the switch in the on position ready for the insulation resistance test.
