Whilst tidying some wiring from a now obsolete socket position in a kitchen..

(after the builders knocked a new doorway through to a new extension)

I opened up this socket where cables for the now redundant socket went to....

and found a very nice arrangement for extending the ring..

and converting a single back box to accommodate a double socket

from a slightly different angle.

There is a very clever use of "same colour" cable identification..

where 1 x red = Neutral, 2 x red = Live! :eek:

Then there is all the wires are cut to short to terminate correctly

so nice bits of connector strip probably only 10A or 15A rating? extend the wires!

The nearest cable coming from the bottom is folded over a very nice jagged cut in the back box....

only needs a bit more pressure for the metal to cut the PVC!

And its one side wall of an old single socket box folded over a cut-in half new box to make the width for a double socket....

So...

Option 1: close it back up and pretend you haven't seen it!

or...

Option 2: Tidy it up with proper back box, longer / new cables etc......

Just waiting for the filler to dry off a bit before it can be finished off then go back. :) :coffee

We still have the four cables entering the box

Now all through correctly grommeted knock-out holes..

The original ring pair and the two extended ring pair..

so two Lives Neutrals & Earths still need connecting through by-passing the socket..

so used 3 x 2way 32A rated level wagos.. Simples! :D

:)

 
Badge wont be happy with you messing with his work!!

 
whats the issue with using 15A connector blocks exactly?
Circuit is 30/32 amp and it is possible that current could be flowing through those conductors so a 15 amp connector strip could get very hot and fail also they are termed not mechanically sound if they are not affixed to box.

 
Lovely job SL :D

Why do they make the earth sleeve so baggy? 2mm or 1.5mm would be more than big enough for most uses.

 
When I ordered mine from SF the smallest they has was 3mm. Bought 100m, must have 97m left and I've had it a while! :D
i also get the 2mm sleeving on a roll - much easier than in a plastic bag, that somehow manages to go AWOL within 30 seconds of opening

for some larger sizes / colours i dont use much, in a bag isnt much of a problem. only keep a few mtr of each in the van

 
You boys should get a room! Whats a mil between friends:innocent

All i know is mine is green and yellow, maybe Specs likes the baggy look? Maybe its coming round in fashion. Could always get old skool green sleeving and tie die it with yellow?

I think it looks messy and sort of 'baggy'.

Still would prefer all three cores sheathed when manufactured!

but a socket is only rated to 13A, most double pole isolators 20A and switched fused spurs 13A yet they are fine on a 30/32A circuit.

tbh this is just something that I have been thinking about lately(sad i know) as at work the guy in chrage of the electrical dept has said the same as you but tbh i think its twoddle, hell even the cable isn't rated to 30/32A!

That earth sleeve is big enough to fit on a 2.5mm CPC on a 6.mm T&E, which does me fine for everything upto 6.0mm T&E

Why carry loads more different sizes just cuz your lighting circuits are a tad smaller on the CPC's?

I Keep a bit of bigger stuff for me 10.0mm T&E cables, but don't need as much of this in one go..

so that roll is a bit smaller!

Baggy indeed! :| :C

I reckon you could pull 32a through one of those connectors with no problem. The only thing that really limits connector blocks amperage is the size of the hole in the block. The metal is far greater size than a bit of 2.5 copper cable,

How much metal is in contact in a through crimp ?

How much metal contact is inside a Wago or similar connector ?

Also there is something very wrong with your circuit if 30/32A is going through that connector.

However the regs say you should follow manufacturers instructions so a 30A connector should be used that the cable will rattle around in and not actually be tight under the screw unless you triple up the core.

exactly the reasoning behind why 32a ring finals are dangerous

a cable capable of carrying at max 27a(oiro) protected by a 32a device, and its called safe......

makes you realise that BS7671 really is a bad joke.

 
for me earth sleave is kept in the bag. small hole in the bag and ties cut off. that way you dont get a mess.

also if your ment to fix choc blocks down then how do you do it with a wago ? (no rude answers plz)
