Mmm Pauluk I can have some sympathy with you on your loathing of the ring circuit.
I seem to remember in the 1970's there was an idea banded about (London I think) to use a system where a ring main was wired all around a flat (sorry appartment) and the lighting for each room was spured from the ring. Dont know if it was ever put into practice. I tend to look at each ring main application on its merrit, I have seen some horrendous ring circuits running into what appears to be miles of cable. One problem I find is that lots of sparks only use these damnd plug in testers with lights on to check to see if they have a L,N,E at each outlet.Then its testing finished. With 2.5mm single strand cable there is a great tendancy for conductors to get damaged whilst stripping and even partialy cut through with terminal screws and then broken when being pushed back into box's (have done it myself)without noticing. The only way to be sure that the conductors are sound is by continuity testing end to end of the ring and R1+r2 and saddly it does not get completed in a lot of cases. I wonder how many circuits are out there that are not rings connected to 32amp breakers D type in a lot of cases.
My own preference is for 4mm cable on a radial circuit I must confess. I think 4mm stranded cable is mutch more user friendly. Mind you there's still the need to do Ri+r2 to prove continuity and polarity.
Dave, It does not matter how big the horse is if he kicks you it still hurts, my phylosophy has always been to treat every circuit as live even if you know that there is no supply connected that way your gona live longer. We dont want to be talkin about dyin it ain an option. What voltage drop are you allwed on your systems?
