2 Way Switching of 2 Lights Tested for Continuity of CPC, Polarity & Insulation Resistance

Student training aid for testing continuity of CPC, polarity and insulation resistance of our Steel Conduit lighting circuit. Remember to test both sides of the strappers of a 2 way switches. Using a MFT Megger tester set to ohms and megaohms scales.

🕕 Time Stamps - Cut to the action 🕕

00:00 - Continuity of CPC and polarity with 2 way switching
00:43 - Kewtech adaptor set up with the Megger MFT
02:53 - Staring the test
03:53 - Proving the metal conduit is connected to the CPC (earth)
05:47 - Proving the switches have a CPC connection
06:38 - Carrying out the insulation resistance test
08:58 - Operate the switches and repeat the insulation resistance test

Videos are training aids for City and Guilds (C and G) and EAL courses Level 1, 2, 3 plus AM2, AM2S and AM2E.
