Wiring a radial circuit

What is a radial circuit?
Well a radial circuit is a mains power circuit that can be found in most homes and feeds power to the sockets and lights. It feeds power from one point to the next point and does not return power to the fuse board (consumer unit).

Below is a description that applies to the power sockets (not the lighting circuit). Lighting circuits are different.
There’s not a limit to how many sockets you can have in a radial circuit as long as the circuit is kept within a radius that does not exceed 50 square meters. Similar to a ring main you can add spurs or extra sockets to this circuit. Although you can’t add more spurs than the existing amount of sockets.
