How to Test a Ring Final Circuit - Ring Main or Socket Circuit - Ring Continuity & Polarity Tests In this video me and Marcus look at dead test number 2 in BS7671. In the test sequence this is "testing continuity of ring final circuit conductors, including protective conductors". We go through all 3 stages recording the results and we show the calculation for R1 RN and R1 R2 from r1, rn and r2 end to end readings. We prove the circuit is wired as a ring final circuit sometimes called a ring main

EICR Ring Circuit Fault Finding Issues - Testing an Open Ring Circuit & Low Insulation Resistance On site with electrician Matt testing and fault finding whilst doing an EICR (electrical installation condition report). This video will be used to support classroom teaching at college. Matt highlights issues with the ring final circuit (ring main) open ring test end to end and low insulation resistance test. NOTE - Some further discussion have been left for the classroom lessons. This video gives
