Plug socket circuit question

[Billy22]

I just wanted to confirm if the wiring for plug sockets below is fine (pretty sure it is).

1. I understand cleanest way would be to wire 6 plugs in a row: 1 to 2 to 3 to 4 to 5 to 6
2. Due to insufficient cable length the above isn’t possible, so considering this alternative circuit: 1 to 2 & 4 & 5 (effectively splicing); 4 to 3; 5 to 6

EDIT: Diagram below is wrong - posted proper one below. 1&2 and 3&4 are doubles so there is actually only a one spur - a double off a double. The whole circuit is a 32A ring

TIA!

With 2.5 mm² cable from a 20 amp or lower overload device not a problem, but not if supplied from a ring final.

What about the earth???
L&N are ok if you are looking at the terminals, ie at the back of the socket.

It’s on 2.5mm cable and on a 32A ring circuit. Technically, 1 & 2 and 3 & 4 are double sockets if that makes a difference? So mains goes into 1 which is a double and continues to 5, while also running a spur to another double (3 & 4).

Earth emitted for simplicity, but wiring follows the same logic.

Then it would need to go to a fused connection unit first.

You can’t spur off a spur unless you add a fused connection first

Why do you want so many sockets?

EDIT - wrong drawing

The 4 plugs on the left are in a single unit, ie 2 x doubles. It is a Delta S1988 unit with 2 x 2 Gang 13A Switched Sockets

Would this be ok?

No. That's no different

it would need to go to a fused connection unit first.

I think he's saying it will mostly become part of the ring - see the extra L and N at the right hand end.

 

[Billy22]

Sorry all, feel like I’m wasting your time as I didn’t understand how double sockets were wired… The corrected wiring diagram I am proposing is below.

The 4 plus on the left are two doubles. So I am only spurring one double of the other.

Ah - if that is the case then it is alright.

However, I see the original post has been edited to say that, but where does the new wiring start?

Sorry, I got confused drawing it initially and wasn’t sure about all the terminology either. What I really mean is the above quote - a double socket spurred off another double socket.

As you can probably work out from what has been said, if one socket (doubkle or single) is part of the ring, gthen you can spur one ((single or double) socket from that without the spur having to be fused.

As I've said Per the diagram (which is 'guidance', not a regulation) one can spur one (double or single) socket in that way). If you wanted to know why the guidance does not seem to 'allow' two single sockets, you would have to ask the person who wrote it!

Kind Regards, John

It used to a few additions ago did it not?
Only reason I can think of is you'd have 2 cables in the first socket which could be mistaken for part of the ring, maybe.
