Lot of useful information in this video. Parallel paths are a pain where there is continuous metallic containment especially in commercial / industrial with metal clad structures as well.
That you for some of this information given. Am almost finished on my level 2 I been in the trade for meany years but there is always more to learn. Dimmers have given me a problem. Ended up linking I used to have a battery bank 2 x 9 v I used to clip on an test at each point. Did show some problems after Mr DIY had been in. Then tell me it don't mater it is AC. This is why I will only fit double pole sockets.
God, you covered everything there comprehensibly. I agree with what you said regarding THE r1 + R2 test. I would like to know how you test an R.F.C with m/clad sockets on trunking as without disassembling it is hard to omit the containment parallel path.
In your experience how many sparks actually prove continuity at more than one point on each circuit? I've only ever seen people test the end-of-line, even though we all know we're supposed to prove it everywhere...
Fantastic video so clear and to the point. A great insight with all the considerations to take into account in the real world. I just subscribed and look forward to seeing more of your videos Many thanks Chris.
Thank you for this. In the real world time is a big factor and when you have a 3 floor house to test it is not so practical to try to undo ceiling lights and ceiling roses that might be stuck with paint and age. So any light fittings that have exposed metallic parts wouldn't it make sense to just carry out the R2 by clipping on to the exposed metallic part? LIM any fittings which are stuck from old paint? And polarity can be checked by manually applying the voltage tester to the Edison screw?
Good advice. where did you you get the info from for the alternative test of RN+R2 test instead of R1+R2 on circuits with electronic equipment? thanks.
