I plan to extend the number of power points in a domestic property. (The planned extensions are within the "non-notifiable" guidelines of part P of the building regulations).

However, I've found that the property is wired with radial circuits, rather than a ring main which I'm used to. It has four circuits: one 30 amp direct to the oven, another 30 amp power circuit and two 5 amp light circuits.

My question is, "Is there any way of identifying whether a particular electrical power socket with just one incoming wire is located at the end of a radially wired run or is just a wired spur from another power socket? In both cases the power socket in question has just one incoming wire.

Advice or pointers would be welcomed, experienced or not.

Jhdj13,
ericmark posted a really useful publication from BSI which spells out radial circuit arrangements really clearly. I can't find the post but if you google "BS7671:2008 corrigendum" you should find it.
