Verify R1 + R2 testing of a radial lighting circuit - covers fault finding and write-up. Part 1 of 3

Hello and welcome to Part 1 of this video series, by Adrian Davey from Pure Electrical Training.
In this video, we discuss the process of verifying R1 + R2 within a radial lighting circuit. I also explain the definition of R1 + R2, how to use test methods 1 and 2, and how to verify your results using the IET's on-site guide.
I then demonstrate fault-finding on this circuit and how to write up a report for the person ordering the work.
Remember, this video can contribute to your off-the-job training for apprenticeships or serve as part of your own CPD.

Thank you very much for the video. As an enthusiastic amateur, I have plenty of theory but not so much practical experience. Your explanantion is very clear as is the logic behind analysing the readings from your MFT. However they all depend on having a fairly good idea of how long the cable runs are (5m, 19m and 35m inyour example) - How would you establish that on site?

[@Pure_electrical_training]

Thank you for the feedback. On-site you would take a rough guess at the measurements and your readings would ‘be in the ball park’.
As long as the maximum measured resistance, combined with your Ze, is below 80% of your max Zs, then your circuit is compliant

Hi Adrian, may I ask you to make some videos for someone who will take the 18th edition exam, I am a bit confused. Thank you so much

Great video Adrian - how do I get in touch with you? Cheers
