I'm trying to get 3 wires into an electrical double socket,
6mm, 4mm and 4mm
and making a bit of a mess with exposed copper showing.

Is there a technique to doing this?
maybe tape the wires together before inserting?
or remove a few strands of copper?

They feed 5 double sockets in one room, radial.

Is there a double socket with bigger connection terminals?

Or must I gouge the walls and rewire them somehow?

I dont want to have hidden junction boxes under the floorboards or anywhere in my house

I doubt there are any sockets that will take larger than 3 x 4mm and even that will be a push.

You'll probably have to use terminal strip and pigtail to the socket.


I wonder how big a botch it would be to crimp a /very/ short length of
4mm onto the 6mm (with the crimp inside the back box) given it's not as
if the whole current would flow through the 4mm without a heat sink.

Not surprising. 13 amp sockets must be fitted to regs. And the terminals
made for 3 x 2.5mm, or 2 x 4mm. IIRC, you can spur one socket off a
radial, but then 2.5mm would be fine.

though, as Owain mentioned, some are spec'd for up to 3 x 4 mm (or 2 x
6mm stranded)

The GET Ultimate sockets from TLC (Schnider branded) claim to have about
16mm^2 of terminal capacity - but even there you may find that lot a
challenge

Is there a technique to doing this?
maybe tape the wires together before inserting?

Dressing the wires so they arrive at the terminal straight and together
can help, as will a deep backbox.

You may find that doing the terminations in a wago, with a flylead to
the socket is easier.

or remove a few strands of copper?

No, really not!

They feed 5 double sockets in one room, radial.

Is there a double socket with bigger connection terminals?

See above

Is this permitted (assuming the correct rating is used)? I thought
these terminal blocks were regarded as a botch.

I don't see the need for the 6mm cable, even for a 32 amp radial
surely 4mm is sufficient, it's certainly what the OSG specifies isn't
it? (Unless there's a very long feed to the room)

Or was already there!


I would try wagos and a flylead.

If needs be just put two of the existing cables into the wago and one
into the socket.

You can legitimately reduce wire size so long as the circuit protection
is sized correctly for the protection of the new smaller wire size.
(which is in this case it probably already is)

I've decided:
2 Wagos for line and neutral in the back box.
Earths are thinner so all fit into the double socket.

Thanks for the advice.

I havent yet calculated the correct MCB sizes for all the circuits,
some are still evolving.

There's still one old rubbery wire to a light switch!

Thanks for advices

Most will likely be "standard" circuits I would have thought.

There's still one old rubbery wire to a light switch!

IME most of those are "well past shagged" by now :-)

well when my cousin and I found that sort of wiring in our
Grandmothers house in the 1970's, just looking at it seemed to
make all the exposed rubber just crumble away to dust. Cousin
(GPO apprentice) did an emergency rewire + new CU.

Thanks for advices

When we moved into this house in 1977, some of the wiring was lead sheathed
-with a live sheath! That was in the bathroom !

Mine had loads of lead too, but nominally earthed. Bare copper wire
wrapped round the lead at any joints, etc, and connected to the mains
water pipe by the fusebox.

Where a connection had been made, the insulation was a bit fragile. But
cut the cable back a bit (out of curiosity) and it was in perfect
condition.
