Live Test Re-check Polarity and Functional Testing of our 2 Way and Intermediate Lighting Circuit EAL Awards City & Guilds Students training aid for checking polarity and functional testing (LIVE) under controlled conditions within a college environment our basic lighting circuit. The first live test is check polarity of supply using an approved voltage indicator. We are checking that the switches operate and that includes the MCB and the RCD which in this case is a RCCB. Videos are training aid

Why Testing Grid Switches Can Be a Nightmare for Electricians 1 Way Lighting Circuit Wired in Conduit - Continuity of the CPC & Insulation Resistance Tests In this video we look at carrying out the dead tests on our 1 way lighting circuit wired in PVC singles in a plastic conduit exercise. I demonstrate how to set up my Megger MFT tester and then carryout the continuity of CPC test and include the polarity test at the same time. Next I go on to demonstrate how to carryout the insulation resistan
