Fault finding on a Ring Final Circuit using R1+R2 & R1+RN, the only way to prove polarity AM2 AM2S

Hello and welcome to my video on Fault finding a ring final circuit using R1+R2 and R1+RN, which is the correct way to prove polarity. In this video I talk you through testing end to ends on the ring to prove you have a ring to start with, how to check your r1 and rn are within tolerance, which would show you if you had a poor termination, before finally checking the r2 value if you have twin and earth, using the ratio of 2.5/1.5 = 1.67 times smaller. I then show you why we connect into a figure of eight, and then create a table to show you how you can prove the fault, before removing the socket and how you can check polarity at the same time. This will save you valuable time when you are fault finding in the AM2, or at work. I hope this video is useful and as always, please like, share, and subscribe to get these important messages out there. Take care Adrian
