I need to move my consumer unit to an opposite wall as the wall it's on is going to be demolished and therefore I need to extend all the rings and radials. An electrician said the best thing to do would be to put a bank of junction boxes within the ceiling void with a trap door. Here's the query, The first ring I worked on was the first floor power circuit, I've taken the two supply cables from the CU which fed the FF ring and connected both these cables in a 3 terminal junction box with the two ring cables leading from here and returning to the same JB.
The ring worked briefly but is now no longer working, the RCB that feeds this ring isn't tripping but there doesn't appear to be any current when checked with a neon!
Was I wrong to connect all four ring cables in one junction box i.e. the two that come from the RCB and the two that supply the ring? Should I have had one cable from the RCB going into one junction box and then the ring starting from there and returning to a second junction box with a cable returning to the RCB from there?
Would using just one Junction box cause a fault in the RCB?
I just need to know the correct procedure for extending these rings and what has caused the RCB to malfunction?
Thanks for any guidence before I get the electrician to do the actual reciting.
