Haha! Thanks for the compliment and I've no idea why it isn't great quality. I've obviously ticked some box or not ticked some box, and it's uploaded the quality poorly. I'll sort it out for the next videos! 😂
Hi there, if you're doing the correct cross connections for the R1 + R2 test, as shown on p117 OSG. Then that reading is the correct R1 + R2 value. The test you would have done before, the end to end test for live, neutral and earth. Its those values, if you add the live and earth end to end value together, then divide by 4. You should get the same as the R1 + R2 value.
Ring circuit do you mean to do your L-L , N-N and CPC -CPC for step 1 And step 2 and 3 you do R1 +Rn and R1 +R2 but use the plug on the socket to step the process?????
