How to Test a Ring Final Circuit - Ring Main or Socket Circuit - Ring Continuity & Polarity Tests SparkSafe 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

The ring final circuit (ring main) is a unique British socket wiring system. More complex to test and install compared to radial circuits. In this electrical tutorial, Joe Robinson explores how the current flows in the branches of a ring circuit. This video demonstrates why you can't use a 16A junction box on a 32A ring final circuit, a topic explored in a previous electricians' Q&A - https://youtu.be/LreZCnItWfM 🕐 TIME STAMPS 🕕 ====================== 00:00 Ring final circuits - (yes loads of
