I have knocked down a dry wall that housed some plug sockets and light switches. These will be relocated to a nearby existing wall. The problem is that the cables are about 0.5m too short as they are. Hence need extending.
If you are extending/altering circuits, routing cables in wall and floors, there are a number of regulations you need to comply to. * The use of safe permitted cable zones * A knowledge of the regulation concerning notching and holing joists * The requirement of 30mA RCD protection * The use of maintenance free joints, where joints are made inaccessible locations
The cable used to extend a ring final circuit, when using flat twin and earth cable cannot be less than 2.5mm2, the lighting circuit will likely require 1.00 or 1.5mm2.
I suggest you get the electrician that is going to certificate the work, to inform you of the above prior to you starting this project.
