unknown spur connections

[maguire]

Hi again posted query associated with this question and got a couple of good replies however on further investigation I have the following situation
in a kitchen ring there are 4 spurs but none of the spurs are fed from the back of the worktop sockets the assumption is that when the kitchen was refitted the ring was split and junction boxes used, now if they have fed two spurs from one junction box and then repeated the procedeure for the other two will that comply my immediate reaction is no, having refered to the IET ring chart as suggested by another member (sorry mate I did not note your name although i think it was eric?) the arrangement I have described does not appear as accepable, all cable is 2.5mm2

First question.

Now it has been split is the ring still a ring? Have you done the relavent tests to confirm this?
If not the CPD needs to be 20amp maximum.
In that case its a radial and you can have as many spurs coming off the wiring if you like but (IMO) 20A won't hack it for a kitchen.

If it is still a ring then you are only permitted one spur from a socket (etc) on the ring. Otherwise it doesn't comply with regs - as you have stated.

Hi TTC
Yes its still a ring, and r1+r2 values confirm that they are spurs, also they are defiately not off the sockets, the other thing is if they are in JB,s they are inside the partition wall and therefore not accesible, that in itself is worrying enough. so am I right in saying that if the above is the case they should be on FCU,s I know that it will not resolve the JB departure but it will at least offer some additional protection in the mean time

The best protection to offer would be to swap the 32A MCB for a 20A variety. This will then comply, as TTC states. the only problem then being that you have a 20A limit on your kitchen sockets.
