Simple Spur from Ring Main

[fat32]

Hello

I have a ring main on a 32A MCB protected by an RCD - I want to add a fused spur at 3A. Load is minimal - about 1A tops so there is plenty of room, but is it notifiable/do I need an electrician/will building control be all upset?

In what room(s) will you be altering/extending the wiring? Unless kitchen or bathroom (and assuming there will be no work outside the house) then you probably don't need to notify.

Bedroom, spur to loft area.

Trunking (empty) is already buried so cable is > 50mm deep in plaster - did check 7671 - was just unsure of building control bit

Thank you

So you have RCD protection and the cable is within a prescribed zone?

Yes - ring is on an RCD and its a nice zone, straight run from socket upwards
