I`ve been thinking

OK the title might startle some who know me.

Ring Final rules.

What is the intention behind the rule "no more spurs than points on the ring".

I think most of us who have run rings would almost exclusively put every point on a ring and no spurs at all.

Spurs are then usually just additions.

One spur max per point.

One spur allowed at origin.

If I saw a ring with say 12 points on ring and one ring per point and say 1 point at origin that would be 12 on ring and 13 spurs that would not worry me.

In fact if I saw say 5 points at origin it would not worry me either.

If I saw 12 on ring each with one spur then 5 spurs at origin then 11 spurs on joints between points woul I worry?

No I would not although this "golden rule" would have been well and truly broken.

I think the rule intention was purely good housekeeping to keep us all on the straight and narrow.

In fact some on here have mentionded a ring in a loft with junction boxes dropped dow to spurs. Therefore all spurs and not on ring.

Note I did not pick the number of 12 points on ring for any reason, I could have picked 5 or 50 or 5000.

    O.K. Years ago I have seen bungalows being built. Sometimes a large metal or plastic water tank would be installed in the loft before the roof was fully fitted in place, as the loft hatch would not allow access for the large water tank from inside the completed bungalow. But with electrics we would not install junction boxes in a loft space when rain could enter them. So, on outside walls of a bungalow we would be fart arsin' about with junction boxes in a loft space in the dark with limited head room to cut into the ring final to drop spurs. I don't fancy that at all. Plus, look at the additional labour and materials time involved. I much prefer to terminate the ring cables at sockets where I can sit down to do the job.
