Radial Wiring in a domestic property.

Postby Jhdj13 » Fri Jan 02, 2009 4:10 pm

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.

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.
