Thanks

[johnsville]

Recently I posted asking about a problem I had.
//www.diynot.com/forums/viewtopic.php?t=272147&start=0

After three pages a solution was reached by splitting a ring and using the two cables as radial circuits with their own mcb's at the CU. This was done and works very well. It saved a lot of time and disruption and expense. Thanks to all who were positive in the thread. Unfortunately a few were very negative, but made up for by those who could think things through and ask proper questions.

Once again thanks.

PS
I read here that only one spur can be taken off one 32A ring. I see many 13A fused spurs above worktops in kitchens supplying many appliances. Would anyone care to clarify?

You must have read wrong,then.

You can have one spur from any socket on the ring so if you had 20 sockets, you could have a spur off each (20 spurs) - not good engineering though, much better to extend the ring if several new sockets/fcus are required.

PS, don't forget to use the

Thanks. I hit the button as well.

That is clear enough. Can a j box be fitted in the ring and one 2.5mm cable run to a socket? OK this is not off a "socket", but still a spur off the ring.

Yes

How many j boxes? Is there is limit?

From the back of a socket is is one per socket, that is easy, j boxes are different?

If you asked a question, the correct answer to which was "No", then that was indeed a negative answer. But if the answer you wanted was "Yes", you got bent out of shape about it.

If you made an assertion which was incorrect, and you were told it was incorrect, then that was indeed a negative response. But if you wanted what you had asserted to be correct, you got bent out of shape about it.

You can't expect people to not give negative answers just because you wrongly only want positive ones.

No J boxes at all is best.
Each join in a cable is a place for problems later on - screwed joints can come loose over time. That is why ALL J boxes must be accessible.

No, you can as many as you like, but only one single or twin socket per jb.

It's a commonly-seen assertion that there should be only one spur arising from a socket or jb, but do the regs actually say that (and, if so, where?)?

IF one could fit all the cables into the accessorfy and IF one could find a socket or jb rated for 4 conductors per terminal (may be difficult or imposible with sockets), I can't really see any fundamental objection, provided the total ratio of spurs to sockets doesn't exceed the OSG guideline of 1:1. After all, in terms of 'where the ring is loaded', it would not be materially different from having spurs arising from each of two sockets or jbs which were only a few inches apart.

Having said all that, I do agree that it's not a very desirable practice, primarily because of the problem of fitting in all the cables - but (as with many of these assertions we see) I'd be interested to clarify the situation regarding the regs.

Kind Regards, John.

To the OP post.
You may get differing answers ( BAS was almost there). But thats because it is a forum, you may not like all. Or the tone, bad luck, you asked.
Answers may differ, some know more than others. Generally we all learn from an "extended debate".

So your bad " kin hate that saying" for not understanding.

But TY for coming back with a TY, even if it was to ask another quest

 

[sparkwright]

Yes

No, you can as many as you like, but only one single or twin socket per jb.

If we are talking about ring circuits, I thought the number of spurs must not exceed the number of outlets directly on the ring.

 

[TicklyT]

In kitchens it is common practise to run a ring via several Switched Fused Connection Units, and describe the outlet from each SFCU as a fused spur. As each SFCU is connected at a different point along the ring, and each spur is fused down at it's source, the SFCU, the design meets or exceeds the criteria above.

The above design is a different kettle of fish to a design incorporating multiple unfused spurs off a ring.

I would echo that each joint in a cable is a fault liability, so eliminating unnecessary JBs, and running any spurs from existing accessories is better practise wherever possible. I don't think anyone has ever designed a 'pretty' JB, so there will always be a temptation to conceal them, turning the installation into a maintenance nightmare.

Thanks. All clear now.

Taylor is right, no j boxes is best. Unless the wires are soldered I suppose.

I'll ignore the other pillock

It's not the no that's the issue, it's the way it's said.

You are the number 1 for coming over as rude / antsy / blunt (add in any one of a few 100 'negative' adjectives).

Communicating is a skill, and the majority of your answers may have correct content, but do lack tact / softness and being blunt is simply rude. Being consistently blunt creates a online persona that you could take lessons in charm from Victor Meldrew
