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

How to Carry Out the Continuity of the CPC & Polarity Test on a Lighting Circuit Using an R1R2 Link EAL Awards City & Guilds In this video I demonstrate how to carry out a combined continuity of the circuit protective conductor (CPC) and polarity test on a 1 way lighting circuit. To carry out this test the circuit is proven to be isolated and the main switch is locked off. I use BS 7671 On-Site Guide section 10 to illustrate the testing procedure and the position of the link within the consumer
