so we're back at the rig I'm using to simulate the 2 plate method that's where we take the supply
or feed to the switch so here we've got the line neutral and CPC from the consumer unit be in taken
directly down to a switch from the switch we've got a switching line neutral and CPC coming up
to the lighting point that we're simulating in the ceiling the reason we said we'd use the two plate
method would be to reduce the number of cables at the lighting point itself so that makes it
easier for us to fit things like LED downlight so what I'm going to do in this presentation
is actually swap out the batten lamp holder for two LED downlights I'm going to use the easy-fit
connector from Collinwood in order to make my connections it means I'll have coming in one cable
with a switching line neutral and CPC and then go out to my second downlight with another switching
line neutral and CPC says we're doing this part of the presentation let's take this apart an order
that we can get to the cable so in the real world you wouldn't have perhaps had a batten
lamp holder you would have wired it directly into your down lights let's get rid of this
from the first part of the presentation I did or explain the connections let's undo my conductors
take off my batten lamp holder then we can look at using these easy quick connectors hopefully I've
got a little bit better I did a video on those the first time I'd use them so let's get rid of
and take this off so remember this would all be done in the ceiling I'm just simulating it
for testing purposes which might be a second video so got my cables exposed got my easy
fit connector okay so we've got switching line CPC and neutral cord grips up here make sure we
get these at the right length so the time being I'm gonna get rid of a clip that look to dress
in my cables like so so straightaway we're the wrong way around but this would be in a ceiling
so I'm just gonna twist it over for the time being just to make it easier so let's get that
out of the way there and we can now look at making some of these connections so let's get
it down to length there is a length specified within the actual body itself but see if we can
work it out do the same one on the line itself like so break all the rules I have a college
just nip off my conductors let's get rid of a CPC sleeve into length as well hope I'm not too long
snip on back maybe a fraction longer over another one pulled up on it so here we go
so let's push our Neutral connection in which our line connection in like so then we'll follow
it with our CPC connection into that position there anything is the cord grip probably see how
easy how to take out so probably the done we're going in for the cord grip there hopefully these
slides straight back in just proves a really good point this does let's move the CPC across now you
can see why they call it an easy-fit connectors because obviously wrong side of the cord grip bang
we're back to the right side of the cord grip we made our connections like so all we need to
do now is obviously add another one to go to my next downlight so my first cable is in position
I'm just going to slide the second pointing I've already pre prepared the end so in through
here it's just a case of getting them lined up correctly into the right positions so there we
go and then just pushing them home so now they are connected can't pull those out they're fully in so
position them within their cord grips now like so and then it's just a matter of lever in this into
position so those back section goes on first and clip the front section down and we've made our
easy fit connector now so cord grips are in place can't pull those out conductors are in you can see
clearly in there as well for a visual polarity you can see the neutral CPC and line conductor
as well we're ready to prepare the second end for another one of these and then obviously the
connection for the actual downlight itself so I'm ready to make the connections on the other end of
already prepared the cable itself you've already seen me do that just show you again how easy these
are to separate two sections and then to open these up there's a little window in here you push
your screwdriver into both sides of those and then you should be able to just leave the two sections
apart like so the only thing I will keep saying is to myself is this cord grip thing or remember
to make sure I get the cables into it before I start so let's position it like so let's go if
the cord grips up put it underneath keep missing that and then obviously we need to just locate our
positions so there there there and just push them firmly into place and see how easy that was to get
that in position it onto the cord grip section and then the back goes in first like so and then we
just close down the front in order to clip the two sections together cord grips in place and again
you can clearly see your connections within there so that was a straight forward we've now just got
prepare the other end for both the LED downlights next so we're going to prepare the connector for
the end for the LED downlight there's two screws in here in order to separate the two sections so
we open those up be careful not to lose the screws this if you're on a ladder obviously
stepladder trying to do them in the ceiling you'll be careful we can't lose those because you do need
to undo them to separate the sections so as they come out in order to separate the two sections
so we're like so and then we've got to make our connections according to determinations in here
neutral line it's double insulated so it doesn't need the CPC again undo the screw undo the screw
hopefully just slide our connections in like so tighten those back up back up so there in position
okay just to prove it to you see the LED downlight is double insulated so no CPC we know it's metal
but it's double insulated so it doesn't need a CPC connection then we've just got rebuild these back
together like so the screws back here and the only awkward would part of that he's dropping
obviously these screws from a pair of steps and then having to find them again and that's our
connection they're made LED downlights and you can see that we can just easily push those together
like so and as you can see through them you've got an easy polarity visual check the neutral
this side goes through to the neutral the lamp the switching line this side goes through to the
switching line on the lamp and you cannot put it in the reverse way round so for us to go wrong way
around won't actually physically go in there's a nice little touch let's do the next one so I
made the second one off-camera so ready to connect back up like so and we can now hopefully see the
thinking behind the two plate method we only have at this lighting point in the ceiling switching
line neutral and CPC coming in and going out and then we carry on for as many downlights as we want
and obviously the last one only has the one cable in making fewer connections at the light and point
itself and therefore easier for the electrician to install and another video presentation when
we go on and do the continuity CPC polarity and insulation resistance test of this circuit because
i like the fact that obviously for an insulation resistance test we have to remove all loads and
this is currently connected so it's connect across line and neutral and would cause you
issues during your insulation resistance test if not damaged the actual fittings themselves
but look at this you just go and you can easily disconnect them to carry out your insulation
resistance test with all loads removed so until the next time i hope this video has been some help
