Okay I thought I knew how to test ring finals, end to end, figure of 8 test etc.
But I keep encountering this scenario:
I've done a PIR today and found no earth on the downstairs ring final.
Upon investigation, the CPC for the downstairs ring is lifted out of the earth terminal inside the CU and both ends of the CPC are terminated together in a choc block.
Because I keep finding this, this is at least the third time, I can only assume someone has done this during testing, and forgot to put the CPC's back in the correct place.
But what test are they doing where they need both CPC's terminated together in a choc block?
I normally split them and do an end to end continuity check (no need for choc blocks, just clip my test leads on), then cross link them to the other L for the figure of 8 test. But never do I join both together into a choc block.
So am I missing something, or what's the mystery behind why I keep finding ring final CPS's not in their right place, but joined together in a choc block?
