finding origin of a spur??

[timtheenchanter]

just been doing some work at home and discovered that I have a spur with 2 doubles on it, one has my washer and dishwasher in it, the other is in the conservatory, where in the winter we use electric heating.

I have checked all the sockets in the kitchen, and not found the origin, so I have a sneaking suspicion it is under the (tiled) floor.

except ripping the floor up, is there any way of finding the approximate point of the join?

my plan is as a temporary measure add an FCU in before the first socket, not ideal in my mind as it leaves an unknown length of 2.5 to the junction.

I either
a: want to find the junction and make it up as part of the ring (probably leaving the conservatory as a spur)
or
b: take the washer/dishwasher socket back to the C/U and make a radial (there are a couple of spare ways.) which would work well for next year when we intend on re-doing the kitchen

I am aware this is notifiable, but by the time the permanent solution is going to happen, I hope to be registered.

Are you absolutely sure it is a spur off a spur ?
Are you sure it doesn't emanate from the CU as a radial ?

Using a FCU will cause concern as you will be limited to 13A and the dishwasher and washer will be over that anyway if on together and doing hot cycles, let alone having the conservatory heating on !

If you really want to get your teeth into it then finding a hidden joint box will be a good idea anyway. The radial idea is favourable but obviously comes with all the notification implications..........

Option B is the way to go mate.

Things like this are one of the reasons why I really don't like ring circuits.

When you re-do your kitchen, go radials only!

yes, definatly doesnt come from CU, had the front off to check if it was piggybacked in with something it shouldn't...

I was intending on radials for the kitchen anyway, at the moment the whole house (almost) is on a single ring, just the loft on a 16A radial.

have come to the conclusion it either behind a kitchen unit, or under the floor (dammit)

without applyind diversity, up till now we have had a potential max load of 30A on a spur (2.5K each dishwasher/washer and 2K for heating) so I would really like to find the junction to check it out.

heating for the conservatory isnt a problem at the moment, we dont need it, there is the possibility of sticking a raditor off the C/H in there before winter anyway.

seems any time I do some work in my house, I find some stupidly done electrics, seem the previous occupiers loved spurs, and cable tieing T&E to heating pipes
