Spacing of junction boxes and fcus on a ring circuit
Does it matter how closely junction boxes and fcus are spaced on a ring circuit? I need to supply seven sockets and four individual appliances in one room from a ring. To make a neat job I propose to mount the junction boxes and fcus on a board about five feet long in the loft above the room and run the spurs from this board to the room sockets and appliances.
Would appreciate any comments. Thanks |

Sounds like a hell of a lot of spurs and jct boxes. Any reason why you can't extend the existing ring to include all these sockets and fcus? You'd have two cable drops down to each socket, with no jct boxes in the loft other than maybe the first and last; each socket being linked continuously to the next. David |

Would appreciate any comments. The design of the ring assumes that the load will be reasonably evenly distributed. There is guidance that spurs should not exceed the number of sockets on the ring, and if you are adding 7 sockets as spurs that may take you over. Adding them all at one point may create an unacceptable point load. Depending on what the 'four individual appliances' are, your plan may be either a departure from best practice, or completely stupid. It does not sound a 'neat' job. Why can't you either (a) extend the ring properly, or (b) run a new radial circuit Owain |
