Students training aid for testing continuity of the CPC and polarity of a 2 way and intermediate lighting circuit. Full demonstration using a MFT Megger tester set on the ohms scale.
Demonstration shows how to set up your Megger MFT tester and carry out an insulation resistance test for a 2 way lighting circuit. Test voltage is 500V DC and the minimum acceptable value according to BS 7671 is 1 megohms with further investigation when the reading falls below 2 megohms. Also shows and explains the need to switch both 2 way switches into the other on position and repeat the insulation resistance test.
