Help with spurs from ring main

[timhoward]

That would also apply if the ring was just extended one side, which might be easier?

A further wacky but universally accepted solution - if the intent was to cover this all with a blanking plate, then you could get hold one of these rare animals...

and fit a fused spur so both sides are fused down.

What is that? Never seen one.

What is that? Never seen one.

So you can fit a single accessory (such as a fuse for a spur) where there was a double accessory (such as a twin socket)

To my mind, there’s nothing wrong with the initial diagram. It’s two spurs off two separate points of a rfc…. Just very close together.

Extending the ring is favourable, but may be impossible now if those are existing spurs, and cable route is now difficult.

Switch fuse on a double box is certainly doable with grid switch and fuse modules. Could have a switch and fuse for both spurs on a 4 gang grid…. If you wanted to. It’s not required.

Two general points about fusing down to spur from a ring. Not directed at OP who's trying to make the best of a bad situation.

I'd seek to avoid doing so unless prominently placed for lighting. I've attended a couple of 'faults' where unknown spurs were well hidden and took some finding, with the actual fault being the fuse.

There has been a couple of mentions of 'switched' fused spurs. This is something else I'd seek to avoid, unless a switch is required for functional purposes - again such as lighting. It's not something I've encountered, but there have been several threads on this forum where 'faults' turned out to be due to an fcu being switched off and the poster finally learning the purpose of an unknown switch.

I like to think beyond the 'here and now' and try to make life as simple as possible for those who come behind me. Too often I'm the guy who comes behind and wish that those who were there before me had made just a little more effort

In my opinion, the arrangement in the OP is fine.

I'd also say that both spurs from one connection point is fine too. Think of a twin socket with another twin socket spurred from its terminals, it would only be expected to introduce 2 twin sockets worth of load onto the ring at that point. If two spurs were connected to the same point on the ring via a JB, the same expected load would be on the connectors.

Same here. it took me a full day once to find one tucked away in the loft, for 3 random sockets on the ground floor.

Thanks for all your input guys. It seems to be that it’s down to personal preference on the best thing to do/if it’s appropriate. In my head I can’t see an issue on how I’ve connected as per the diagram posted.
