Ring Circuit With Spur Wiring Diagram. In the diagram here in and out are the existing ring cables and spur is the new cable leading to the new socket outlet. If there is no socket outlet nearby an alternative is to use a junction box.
The cable is installed on the output side of the fused spur to protect all the sockets installed further up the circuit. The spur can be taken from any socket or fcu within the ring main circuit. The rule is that you can spur off one socket from a point within a ring main circuit or unlimited number of fcus fused to 13a.
The cable is installed on the output side of the fused spur to protect all the sockets installed further up the circuit.
If there is no socket outlet nearby an alternative is to use a junction box. Matt is using pvc mini trunking and 2 5 mm2 cable to wire a spur socket from an a1 ring final circui. The spur can be taken from any socket or fcu within the ring main circuit. Matt is on site wiring a spur from a ring final circuit.
