I was thinking about this recently. I don't think that the cross-connection method is particularly reliable for checking the configuration of a ring circuit where you have, for example a very short spur with more than one socket, where the additional resistance produced is minimal.
Obviously measure ring continuity, IR, Zs, etc. as usual.
Thoughts?
A couple of thoughts of mine Handysparks
Good thinking and I seem to agree with the outcome that ring continuity would be assured,but it also seems to entail major disruption at every socket, having to disconnect then test remotely at the dist board for each item and do so 3 times per socket,it would seem to be one very time consuming exercise
The main weakness I see is that the test is also a test of polarity and although the tester is likely to reconnect the items correctly,bad things do sometimes occur and this test would mean it is then down to a plug in jobbie or reliance on not getting it wrong ever
