Back to my cat pee soaked floors and a RCBO protected radial cirucit that is giving grief. RCBO symptoms described by the customer, "it's a nuisance and keeps tripping so we just flick it back up, sometimes it's OK first time sometimes it can take 3 or 4 goes before it resets, sometimes we have to wait an hour so so and it resets, but now it won't stay up at all"!
Quick IR test was appaling. Split the circuit at mid point, 3 sockets on either side.This point, by luck, was an addition to the original circuit with two 4mm T&E to the accessory. One side OK the other with poor IR. (rural location and lots of signs of rodents as well as incontinent cats).
Odd thing was that at every other accessory a single cable appeared from under the floor. Lifting the floorboards on the knackered side I found the 4mm T&E had a JB under each socket with a spur connected to the accessory. This was true on the good side of the ciruit I found out later by pulling another board up.
Other than ease of getting a single 4mm cable up and behind 12" skirting board, I can't see an advantage. Only a pain in the rear for testing the legs of the circuit had I not been fortunate enough to break in at the addition.
Am I missing anything in terms of any advantage in this approach??
BTW, at the point of failure was a desicated rat that had droped off the cable!!!
