Wiring question
 

I have done some minor wiring, which in due course will be inspected.

I removed a socket and substituted a terminal block and blanking
plate. Should I have folded the conductor cables where they enter the
terminal block, or is this a thing of the past?

Either are acceptable so long as you can get a good firm termination.
The only time folding is really needed is with a small diameter wire
into a large terminal, where you may not otherwise be able to get the
screw to grip it.

I strip both wires so they're long enough to be gripped by both screws,
if there's room. Just seems better, doubt if it's compliant with anything.

That's an interesting approach.

I do that with in-line choc block, if there's room under the screw, as it
should reduce the chance of a loose connection.

I was taught that you fold the when you're terminating it, ie it
is the sole wire entering the terminal, and flat otherwise, ie
there is more than one wire entering the terminal.

Would there be an argument for putting both leads into the same side,
so each terminal has two wires going into it, then the wires are in
physical contact and the space is better filled?

I don't have a preference, it depends on the space I'm putting it in.
If it's two cables coming in from the same side I'd put them into the
block side by side. If it's something coming in one end and going out
somewhere else I'd do it end to end, eg a neutral return passing
through a light switch, eg in the wiki:

Thanks. It's actually (unusually) a radial circuit for the computer.
I am bypassing an existing socket so only two wires to deal with and
plenty of space in the box for the terminal block. It seems to me
putting them both into the same side would guarantee a solid
connection and avoid any risk in bending.

A friend - a retired electrical engineer from a major electricity
supply company - will be checking it so my aim is to impress him !!!

Always aim to as near as possible fill the space in a connector, to
minimise resistance. Sometimes you can put two wires in from opposite
ends and long enough to be caught by both screws. Sometimes you can
feed both in from one end. The idea is to minimise the current flowing
through the connectors metalwork, by having the copper side by side.
Fold them over too, if you possibly can.

In the days when we used to solder cable lugs on large cables, if the
lug's socket was a little large, we would be taught to build the copper
up with a layer of copper wire wound around it, rather than rely on the
lead solder.

Neither. Solder and protect with heat-shrink tube. Now are you going to
solder them in-line or sticking out? ;)

Actually. If you are bypassing a socket, I'd go for two in one side of
choc-block minimising movement from the current setup and being easily
removed in the future if you want to re-instate the socket at any time.

With domestic mains wiring no, the connector must be rated as required. If you were designing an appliance and the connections were always done this way, a downrated connector could be justified. Though if you think no current would flow through then you're not skilled enough to do that.

Thanks. Maybe not no current but a current within the capabilities of
a 'downrated' connector. However, your first comment is determinative
as the work will be inspected.

That's ok if the socket position is having a blanking plate on it so its
still visible, and the screw terminals will remain accessible for
maintenance.

If you are filling in the socket recess, then the joint needs to be a
maintenance free joint (crimp, solder, wago etc). Also consider if
removing all trace of the socket, whether the cables are going to still
be in a permitted zone.

Which is the case here. Also accessible for inspection :-)

So I have two wires side by side inside the connector. The screws are

higher resistance one, where the current leaves one wire, flows into the
connector, then back into the other wire - but surely it'll not be
carrying much current? At a guess a third? Which might be OK for a
smaller connector designed to take a current where the wires aren't
touching?

Thats very arguable indeed given that the two wires have
much more contact area between the wire and the inside
of the hole in the connector than between the wires.

smaller connector designed to take a current where the wires aren't

You don't know the relevant resistances, you're merely guessing. A solid block of conector metal is in fact very low resistance. The wire to wire resistance is variable.

Neither. Solder and protect with heat-shrink tube. Now are you going to
solder them in-line or sticking out? ;)

Actually. If you are bypassing a socket, I'd go for two in one side of
choc-block minimising movement from the current setup and being easily
removed in the future if you want to re-instate the socket at any time.

Thanks. I'm going to do that this morning!

Are you currying favour?

I always feel *slightly* safer with soldered and heat shrunk, even
though I have a fairly good ratchet crimper.

Nothing is as good in my experience as a decent ratchet crimper and
decent crimp terminals never had a problem with them ever:)!..

Always aim to as near as possible fill the space in a connector, to
minimise resistance. Sometimes you can put two wires in from opposite
ends and long enough to be caught by both screws. Sometimes you can
feed both in from one end. The idea is to minimise the current
flowing
through the connectors metalwork, by having the copper side by side.
Fold them over too, if you possibly can.

Does this mean you can use a smaller connector block to ensureÂ* a good
fit, on the basis that if the wires are in contact there is no current
flowing through the connector block?

With domestic mains wiring no, the connector must be rated as
required. If you were designing an appliance and the connections
were always done this way, a downrated connector could be justified.
Though if you think no current would flow through then you're not
skilled enough to do that.

Can you use a 20A junction box on 32A final ring circuit to join two
cables together?

Physically you can use all sorts of things, but it ain't compliant on
a 32A circuit.


Ta:-))))))))))


Not rising to the bait then?

JOOI if you replaced a double socket would you have that inspected?

Well, he's with me now since you mention it :-)

And no, I was not being entirely serious. I've done quite a bit of
minor electrics over the years (including replacing a double socket
recently).

My friend is doing present job because it involves rerouting the ring
main, channeling and entering the consumer unit. Also, he has much
better tools than me !!!

Solder can be very good - so long as the joint is mechanically supported
well enough.

Crimps are easier to deploy in the field usually, and don't have the
mechanical support worry.

In fact, I excelled myself. We dropped the inspection light and M
said it was 'buggered' because it was LED. I was sceptical, checked
and found it was only a battery dislodged.

I think he is following my wiring plan rather than his because it
involves much less work !!!
