Hello all.
I've come upon a slightly unusual query which has even left me a little unsure of the best way to proceed.
I'm testing a ring final circuit wired in MICC. I'm fine until the low ohms end to end testing.
Obviously line and neutral are the same as normal, but I'm not sure what to do with testing the CPC.
As it is wired in MICC each connection has two ends of the ring glanded into the same metal enclosure, so which ever point I test at, I would just be reading across the enclosure, rather than the whole ring circuit.
Would you just prove there is a CPC connection to each point, and as long as Zs values are acceptable, leave it at that, or would you try and break continuity somewhere to do the test?
Also what about R1 + R2? Surely this will be a misleading reading too?
Thanks chaps
