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.

  • HA I thought the normal extra safe solution was to extend the 230V with any old  13A lead out of the window and  dwon the path to as near to the 110V cement mixer as possible, and then park the 230/110 TX in the puddle of cement slops beside it.

    I have also seen someone using a kango hammer  to demolish a brick archway, about 3m up. with the TX on the top of the wall as the lead on the kango would not allow it to be on the ground.

    It is at moments like this that 230V tooling on a fast RCD has a certain appeal after all .
