in this video presentation we're gonna look at the skills required in order to terminate
a twin socket outlet I've mimicked here on the installation cables coming into a surface box
from both sides and we look at the technique in order to get the conductor length correct and
terminate into a twin socket and then I've done the conventional straight into the top into a
box and again we look at the conductor length and how to terminate those conductors into the back
of the socket outlet so if we bring the camera in we'll see nice and close how I'm going to
terminate the conductors into two different style of socket outlets making sure I double
over the terminations of the required length and I need enough cable slack that we can get
it in and out the box comfortably without being too long and certainly not being too short so
I'm gonna make off my first socket outlet here okay so Crabtree branded one and we can look in
the back of it we've got two earthing terminals here with the symbol for Earth so we got CPC to
be connected in these two and when there's two terminals I like to put one CPC connection in
each of those two terminals then we've got a line and we've got neutral okay we're going to double
those terminations over I'm going to work out how deep the doubling over needs to be in order
to get them in and we don't see any copper let's dress our cables to the right length or cut them
to the right length so if they're coming in from the sides as they are here I like him to go past
the box for my students between 50 and 70 mm so we've gone 50 to 70 mm past in the direction so
we've gone past it the same this side 50 to 70 mm this way so our cables are longer than the box in
the opposite direction they came in so come in from this side and they're at least 50 to 70 mm
longer than this way they went from this side at least 50 to 70 mm longer this way so let's start
off by doing let's do the line conductors first so let's take our knife okay and we're gonna do
that well before we do that let's work out how deep these terminals are you're going to
need your electricians screwdriver when doing socket-outlets and not the wonderful terminal
screwdriver that can go back in the toolbox for lighting circuits only so if I open up my line
connection and then if I drop in a conductor I've got kicking around here let's perhaps
drop this one in here okay I can so I'm working now it's not very deep that one isn't okay at
all okay so when doubling that I want to have a little practice go I can work out how deep to
go with that so let's take this shorten it down again so students to practice beforehand with a
scrap piece of conductor in order to work out how far to double it over even that's a little
bit touch-and-go even at that length so I'll turn it back again trim back again and then I'll use
my doubling over technique slightly less in half fold against the pliers and then crush it up like
so see the depth now okay so that's not really deeper talk somewhere because it'd be deeper
than that little were there so students remember have a little practice first get used to how far
we're going in the line connection neutral will be the same often the CPC has a different depth
so we'll have to practice again when we get there so that's my practice attempt just leave it there
so I can see it so let's start off with the line I know again some people remove the insulation
around the brown line conductor using the other kit but I'm going to use my knife as usual so
I take that one pressing awesome firmly that went off if I bring the other one back I can
work the links out to be the same like so around again you pop that off remembering the insulation
material around here is thermoplastic PVC there's a maximum operating temperature of 70 degrees C
so ready to double these over exactly the same as foresight yes in half fold them against my
pliers and then close up the gap like so take the second one exactly the same as I just did we can
do the neutrals or afterwards okay likes so I've got use to that so we take our line conductors I
can pop those into the appropriate place into a visual polarity check that says L there so I'm
gonna pop my two line conductors into here now are they going to go flat or side by side I'm going to
do flat so in other words one top on bottom as we go in like so push them all the way in can't
see any copper get my electrician screwdriver and obviously tighten those terminations up sometimes
easier when you have got a tripod in the way so tighten those up nice and tight okay into
position and then we can repeat the same process obviously for our neutral terminations which is
down here so be careful on neutrals are down here got to get an angled screwdriver and on
this style let's back that screw back bit tricky to get it in they'll be tricky for me if you're
tricky from the student side back to screw back and we can do exactly the same with the neutrals
which won't be a little bit quicker this time just what we've just seen I've got a little bit
used to the length now haven't done the first one okay so press them reasonably firm with my knife
pop those off double over my terminations like so and like so trim that a fraction
so that s my two neutrals done and what I'm going to do is want to put them in and I'm going to have
them sitting one on top of the other like so so I didn't go side by side i sat one on top of
the other when I put them into the terminations lets pop our neutrals in so I've dropped one in
my second neutral in I've got them one on top of the other so I need to feed them in at the
same time like so it was more difficult with the tripod in the way Gaz so let's see didn't
pull back the screw back enough a little easier and we pop those two in front to back so one on
top of the other terminating those up so tighten those off like so make sure they don't come out
so I'll push them back in there difficult now it's down the camera I know but I'm pushing them down
as I'm tightening them off and those two are in position and you can already see that we've got
a reasonable length on those conductors okay which is what I like I like them just spread
out within the box they're a fraction long we can always trim them back they're too short
replace the cables onto the CPC's okay so let's have a look at those let's have a look at the
depth of the CPC terminals first so I'm going to use both of them so there's one either side
let's see how deep they are so back to screw back and let's just drop a little bit of conductor in
there just to have a look all not very deep at all they're hardly going it's also gonna
be a lot smaller to get into there making sure we screw it into the copper and not the PVC so let's
measure these off to the appropriate length I'm gonna use them one against the other as a guide
so that's a CPC outer sheathing to identify the conductor the line and neutral are 2.5 in this
cable the CPC's 1.5 remembering CPC stands for circuit protective conductor like so and we're
going to double those off so I look now how much far we go into the holes it's probably gonna be
about perfect that one double that one over like so doubled over my CPC and drop that into one of
the two CPC terminations if your socket only has one obviously you know to put the two in
together or whether is to Gary likes you to use one in each of the terminating points and we'll
talk about that in the classroom for the best practice moving forward tighten that one off and
while looking I'm fraction just got a little bit a tiny bit off that one okay CPC doubled over my
CPC go into the second of the holes go back this one back some sockets already having backed off
something don't push that through there hold it into position tighten it off and then pull back
out tighten that down okay so you can see my conductors of a reasonable length when they're
that fraction longer they are easier to get into a box than being too short it isn't the other way
around short is good short isn't good for actually long and if they are too long doesn't matter with
practicing we would trim them back but let's see so I'm going to position them down into the socket
itself so making sure that we pull the cables down into position so they can easily go back into the
outlet itself so I've dressed those into the back of the actual socket outlet and that went down
with ease okay comes up down with ease important next trick lean it back tighten them back off
again give all the terminations a little nip up now you've moved them around and wiggled them it's
worth getting back in with your screwdriver and just check in that they haven't settled in and got
a little bit looser so we're doing the top ones and then that little tricky neutral down there
okay so I've tweaked them up got I got that taught on site best practice push it down into position
pull it back recheck your terminations are tight and that can go down see the length easily goes
down into the box too short is too difficult the correct length we'll go back in a box if
you spread the cables out accordingly let's look at the second socket so different arrangement now
with this Hagar socket we go neutral CPC with the earth symbol CPC and the line conductor so
we'll again split the two cpc's across their two neutrals and two long conductors and they're all
side by side this contact and one okay has line nothing here to connect to neutral and only one
CPC terminal and in that case we would have to put the both cpc's into the same termination I
prefer socket-outlets that allows us to split the two cpc's across there I'm going to double these
cables over I'll do that off camera just show you about the length of those conductors so this time
we've come down through the box so our length needs to be 50 to 70 mm longer than the box in
this direction okay so we're going to make sure we're crucial that and I like this one when it's
this way to be nearer the 70 mm so I'm going to do that approximately 70 mm longer than the box
for all the conductors and then I'll prepare prepare these conductors off-camera and then
we'll just look at actually connecting them into the socket outlet again and tight so prepare the
ends of my conductors using the same technique as I did before I dropped in a conductor I checked
its depth or practice one and then dropped it in and what a notice was the neutral and line depth
is a lot shallower than the CPC so when I've made off the doubling over of the CPC's it is larger
than that of the line conductor in this case as well as the neutral so cpc's going further into
the termination than the live conductors line and neutral so when pop those in so again we'll start
let's start with the neutrals okay so what are some of the neutrals this time yep I'm going to
still go one on top of the other so I'm going to position them one on top of each other the
screws are backed back already so they've gone in okay can't see any copper might be difficult for
you to see from that angle but you can't see any copper and I'm going to tighten those up
again when you're in the workshop I don't recommend you're trying to keep out the way
of a tripod in order to do in we go those are nice and tight so let's do the line conductors next so
I'm going to untangle them from within the socket so I want to dress them round so they're untangled
do the line conductor next lay one on top of the other like so and then drop those to in and again
keep some pressure in order to terminate those tight so say and all my videos the one thing I
never seem to do is when the glasses we using the force so the two line conductors are in place and
now cpc's dress them to suit CPC terminal there and hold it in with a little bit of pressure
tighten that one off you can and then we'll tighten this one off into position like so little
half a turn on that okay right so they're in again so you can see there that it's it's longer
than the box which is crucial to me and they'll spread out within the box often DIY wires and
early learning stage students cut them super short it's not a problem my workshop because my learners
will say what do I do if I cut the conductors too short is take out the conductor's put a new fresh
set in and you go again so we're gonna do exactly same as you do before in a position into place
I'm going to move them round so I know they sit in nicely I'm gonna crush it down into position
I'm gonna lift it back off and I'm gonna check tighten these terminations in order to see that
they're tight yep and then obviously that can go down and we can fix it down using the appropriate
three-point-five machine screws so hopefully that's covered some of the skills my learners are
going to need into the workshop so some crucial points to recap make sure our conductors are long
enough in the appropriate direction as discussed in the video between 50 and 70 mm longer than the
box then we look at practicing the doubling over of a termination for each of the holes in order
to work out the depth of those we our conductors we dress them into the back of the box first so we
can see them going nice and easy we've pushed them back into position we lever it forward
recheck tighten because they may have moved as they were settling down into position and then
we can finish it by putting it on and obviously then returning the Machine screws back into the
front of the socket outlet I'll talk about is finished as I say to all my learners every
single termination you carry out and do should be thinking that termination has got to last 50
years so if you using the wrong screwdriver it isn't tight enough the cable is too short the
cable is crushed there's too much conductor is it a circuit a termination that will last 50 years
if you're saying no go back redress it sorted out so once again I hope this video has been some help
