I'm quite familiar with crimping cables end to end, but have an
application where I would like to create a branch - which would involve
joining *three* cables together rather than two.

Is there an accepted way of doing this - maybe with two wires (twisted
together or not?) in one side of the crimp and one (perhaps doubled
back?) in the other side?

Or maybe you can get Y-shaped crimps? [If so I've never seen one].

Advice please!

Thanks for the link. Which of the connectors on that page did you have
in mind?

I'm a bit confused by the descriptions because each connector is
variously described as e.g. "3 pole" or "3 conductor" - and they don't
mean the same thing in my book.[1] Clarification, anyone?

[1] I would assume 3 pole to mean 3 separate connections for e.g. L, N &
E - whereas 3 conductor would mean 3 wires all joined together. Which do
TLC mean?

A 3 pole Wago connector makes an electrical connection between three
conductors.

So to join 3 T&E cables together you will need 3 three pole Wago connectors.

The WA 104 would work, just has a spare terminal. HelaCon do a 3 way.

3 wires joined together. These things are great for light fittings, so fast
& easy.

I don't see why not

as it happens, I've just repaired an appliance which has two wires and a
capacitor crimped together in one

I have crimped 3 cables by pushing two cables in to one end and then putting
the third cable into the other end with a short piece of wire to bulk out
the connector. Doubling the cable over usually means the cable will not fit
into the crimp.

If the cables you wish to join are not two big then put all three into a
closed end terminal and crimp them up.

Or, as TMH has pointed out, Wago connectors. I am using the HelaCon Plus
connectors at the moment which are similar to Wago and they are just superb.

You could do that. You would need to do a "tug test" to ensure that the
crimp was working, but in the main, if the crimp is reasonably "full"
before you crimp it, you should be OK every time.

Twisting together is not necessary other than to ensure that you don't
have stray strands.

Scotchlok possibly with heatshrink,

or solder with heatshrink,

or piggyback crimp possibly with heatshrink.

http://uk.farnell.com/1348548

You can also get y-shaped heatshrink boots, but they cost an absolute
fortune:

Dedicated crimps for 2-wires into 1 terminal do exist - but require a
different ratchet tool. They are used when you want to (say)
daisychain earthing connections into the same ring terminal.

Check the website brand "SWA", I think they carry the crimps & tools.

For cost reasons it is probably cheaper to use one of the alternative
solutions, ie, TLC Direct.

Don't need to twist.
If you you are, say, crimping 3 1mm² cables, you'll probably need
a 2.5mm² crimp. For the end which only has one 1mm² conductor,
fold the conductor over to double up the tickness for better crimping.
I do the same if I'm joining a 2.5mm² to a 1mm² with crimps.

Or maybe you can get Y-shaped crimps? [If so I've never seen one].

You can get blind end crimps where you put several conductors all
in the same end.
