Default Power sockets with 3 cables

Interested to know how others do this, particularly the professionals.
When spurring off a socket on the ring, there's always 3 cables to fit
into the holes. In the past I've tried twisting the 3 together, usually
with pliers, but not always successfully, folding individual cables back
on themselves just don't seems to fit even clamping them up tightly with
pliers- 2 OK but not 3. Fitting them with a single strand seems to be
the easiest way but is it a good idea?

It's probably the only way. It helps to strip them the right length,
and make sure you can see all three ends of the insulation below the
edge of the plastic hole over the terminal all the time you are
tightening them. Possibly twisting them together is a good idea if you
can do it reproducibly, but I'm not convinced. I'd be interested in
what the professionals do.

Never a good idea with modern cables. Just push each wire in, one at a
time and tighten the terminal screw.

UK sockets aren't designed to have the ends folded over.
Folding the single core enough to get it in will probably result in
stress fractures. Then you have to be sure the screw is clamping the
unbent bit and not the bit you have bent over as it could break later
due to thermal creep and vibration.

I never fold them over, if they don't fit and grip its time to use a
different brand of fitting.

Rubbish. The better quality brands allow two ends of a
ring to be folded over.

If you must buy cheap crap from Homebase, the thats your

Why don't sockets have a system where a plate is tightened down on the wire
or wires like we used to see in terminal blocks of old. I'd have though that
was a more positive method, since you would have to have the space for all
three in such a socket. No not seen any either.

It then needs to be wide enough for all the cables though doesn't it?
I agree, I prefer the type you describe as well but often have the

You can do it using an rectangular terminal recess, where the width
matches the scree diameter - so its not easy for wires to be "missed" by
the screw, but the length still allows for plenty of wires.

These GET Ultimate ones I find are easy to get 4 wires into:

I find you can avoid that by starting with the terminal screw fully
unscrewed, at least with most types.

Why do you always post contradictions that have no relevance to what you

Just because the hole is big enough doesn't mean they are designed to do
something.

Its so you can fit three or more cables in.

It's because he is a lonely troll, killfiled by many (and hence all

It's similar with whisky-dave, other than at least he's posting from

Eh? Can you explain further?

Folding the single core enough to get it in will probably result in
stress fractures.


You must search far and wide to find wire of such poor quality.


Then you have to be sure the screw is clamping the
unbent bit and not the bit you have bent over as it could break later
due to thermal creep and vibration.


Screwing it down properly will centralise the cable gripping both equally.
Just as happens with two separate cables.

I never fold them over, if they don't fit and grip its time to use a
different brand of fitting.


Only time I'd fold a cable is where it is a single - like on a spur. No
need with two or three.

All copper cables work harden.

What about the other cables or are you just talking about a spur?
How do you check?

No need on a spur either.

True, but only if they are 'worked', as in continually flexed. In a
normal fixed installation cables do not become work hardened.

I think the terminal specs. are deliberately tight to stop people inserting four 2.5mm2 cables in and creating two spurs off one socket. I do seem to recall terminals used to be wider maybe back in the day when stranded wires were used or maybe with age they look smaller these days😁

Then only bend them once. I do accept this needs the skill to get it right
first time.

All the original sockets in my 1976-build house had the ends of power
cables folded over.

don't think I've ever had that happen. Being nicked by cutters can do it, but not bending it over, even if then pliered tight.

I don't think so. Don't think I've ever encountered any vibrating wall sockets either.

Or fold the cable end over. Seems more sensible to me anyway.

Folding works fine, where there is only one wire to go in the terminal
and the hole is too large. Idea is to fill up the hole, to promote best
contact between wire, terminal and screw.

Sockets vary widely in their terminal sizes - some will accept 3 x 2.5mm easily, others won't, even if they should.

For 3 cables twisting seems to make things harder.

That would be equivalent to putting two sockets on a single spur
off the ring which is not allowed.

There are for sockets, but they don't mandate the size and capacity of
the terminals beyond being adequate.

IME modern socket terminals are easier to wire than older ones,
especially the type with rectangular recesses. That way the width of the
recess can be a fairly close match to the width of the terminal screw,
and so its much easier to clamp a single wire without risk of it
slipping out to the side from under the screw, but you also have plenty
of capacity for 4 x 2.5mm^2 wires due to the length of the recess.

Surely BS1363 applies, whether that covers the size of terminals I
don't know though.


I only have the 2003 edition:

"11.5 Line and neutral terminals in fixed socket-outlets shall permit
the connection, without special preparation, of one, two or three 2.5
mm2 solid or stranded or of one or two 4 mm2 stranded conductors.

11.5.1 Compliance shall be checked by inspection and by fitting the
appropriate conductors.

11.6 Earthing terminals in fixed socket-outlets shall permit the
connection, without special preparation, of one, two or three 1.5 mm2 or
2.5 mm2 solid or stranded or of one or two 4 mm2 stranded conductors.

11.6.1 Compliance shall be checked by inspection and fitting the
appropriate conductors."

Of course fitting 3 x 2.5mm on the bench in good light with freshly
stripped new cable may be a bit different from replacing a socket on old
cable with bugger all slack, with a permanent wave, inside a cupboard.

I'm assuming that folding the end over counts as "special preparation"
which would imply that there should never be any need to fold the ends.

There are quite a number of specs on sockets with screewless connections
