so we continue on our wiring diagrams this time focusing in on AM2 AM2S and AM2E remember the
way in which they want you to wire circuits can change depending on the assessment and they will
always look to altar the assessment we have looked at wiring diagrams using the three plate method
the two plate method and now a slight variation on this which came up on the pre AM2 and AM2S etc
assessment days i'll show you the first drawing i apologize i've had to blow it up from a photograph
but this here it calls it wired through the switch okay for us though this looks identical to me
for our two plate method where we had two way switching i've obviously adapted the drawing
over time so of course we had the supply coming into the switch and it two way and
then i carried on doing other videos with it so let's have a quick look at it back here
the supply comes into the switch there's a connection for the neutral
they're suggesting there's no connection for the cpc in the box so maybe it's fully plastic
maybe it's like a dry lined box that has no terminal in it so there's another connector
for the CPC's and then the three core links to the second switch and from this light switch we
come up to feed the actual lighting point itself and that would be what i would call the two plate
method but they called it wired through the switch so hopefully that video makes us very comfortable
with the wiring for that and if we're given a wiring diagram at AM2 AM2S etc we should be very
familiar with how to make the connections however i still want us to to walk us through the next
one because it's a slight variation and would be good for everybody who watches the channel
so we move that one out of the way and we bring in the next one the next one is this one here
okay blown up from a photograph so i understand it's going to be a little bit hazy but what i
will do is replicate this in a minute and talk you through the connections again wired through the
switch this time we are two way and intermediate so we've got the three switches so look here the
feed comes into this switch but we don't come out of this switch to feed the light as we did when i
did the two plate method i brought the feed into the switch and from that switch i went up to the
light and i extended it in other drawings and other videos produced on the channel to do other
stuff with it so it looks more complicated than it is again if you haven't seen this video on
the two plate method two way intermediate i recommend you check it out back here
feed in this time we come out of the final switch okay to feed the actual light itself so
what happens is the neutral that comes in this side has to make its way through each switch
okay until it gets to the point where it can come up to the light itself so let's follow the neutral
through comes up here down round through and goes up to there and doesn't do anything inside the
switches other than be connected meaning that we then bring a three core through but this
time one of the conductors in the three core is the neutral and the other two are the strappers
so it's a slight variation on what we've been talking about and they called it wired through the
switch so with this drawing here we can replicate the wiring diagram now in the one i've just shown
you they used black as the neutral now i won't for this drawing okay that's just Gaz being Gaz maybe
but i'm trying to de-neutralize black in the old system pre-2004 cable colors black was neutral
and obviously black is now a line conductor in the new system so i'm going to use grey but if
you're given a wiring diagram you should be able to follow it this is just thinking about those
connections if we have to do AM2S where we wired through the switch so this is trying to help you
it might be you get there and it's the three plate method you might get there and be the two plate
method it might be this one and you'll have to look at the wiring diagrams accordingly i expect
NET to change the assessment as they go on if they don't and they use this system so let's bring it
back in if they use this system here hopefully this one of the videos will be the one that helps
you but i recommend you check out the full series of these um wiring diagram videos in order to
increase your understanding of the systems that could be used right okay with this in mind then
let's bring our first cable in so we're going to bring our supply in on our in this case one
millimetre squared twin and CPC cable or twin and earth cable and obviously i'm going to bring the
feed into this switch here and i'm going to come out of this switch here to feed my lighting point
and we're going to bring the neutral through each of the switches in turn okay so we're going to
carry the neutral through the system so it's going to be wired through the switch okay let's start
off with that then so let's start off with our CPC connection i'm showing a consumer unit as always
to have done with our videos it could be that the feed was coming into this switch from another room
but we're going to bring it from here remember the connections inside here do not look like the
connections within the consumer unit we're going to come out the earth bar the neutral bar and the
top of the circuit breaker in order to bring our twin and CPC cable into this first switch here
i have got an earth terminal in mind so i will use the earth terminal in mind but remember the
wiring diagram i just showed you had another connector so in other words something like this
another maintenance-free connector so we've got the one from Wago one from ideal industries okay
so we'll have one of those possibly in the back for the CPC's as well as the neutral
right let's bring our CPC in first remember it will take a route through floors in walls etcetera
in order to get to here i'm just going to bring it around freehand and as always i recommend that you
use a ruler when doing your drawings so let's bring our CPC up and round so let's just work
it out so we're going to be coming through with our neutral then so i'll keep it quite close so
bring our CPC up into our box okay and i'm going to bring it round to my earth terminal i'm just
going to strike a little bit of yellow on that to try and make it a little bit more like the CPC
for those of you are early learning stages obviously the CPC is bear in our twin CPC
cables and we have to over sheave it with green and yellow CPC covering in order to identify as
our protective conductor so next let's bring our neutral through so in this system same as my two
plate method it's going to need to come into some form of connector so as i bring my neutral in
i'm going to bring it into something like this aren't i so one of these style of connectors
so i'll just draw a square for that so there we go that's my neutral connection
and i'm going to bring my permanent line in so my permanent line connection is going to come in and
i'm going to put it into the common connection here so i'm going to bring my permanent line in
and go into common and then we'll see what we're going to do next so my line conductor comes in
be careful now just not confuse the drawing so i'm going to bring it round into here so
there's my first cable brought in that's my supply coming in permanent line neutral and
CPC have been brought into the switch here which is our two way switch so we've got a
one gang one gang switch so one switch on it and when we turn it over we've got our common L1
and L2 doesn't matter which way around we have it okay so that's all we've got so i've brought mine
into the common my permanent line and i need two strappers to go out in a minute in the next cable
so that's brought it in so we brought our feed in here but we're going to bring it
through the switch so this neutral is going to need to carry on so we're still going to bring
a three core across so we're going to link to our next switch here which will be our one gang
intermediate switch okay so it will either bring a cable into the bottom two or the top
two and never across the sides so exactly as it's laid out here either the bottom two
or the top two when our cable comes in as we've talked about in other presentations
our intermediate switch so however one of these now is actually going to be our neutral okay
and i'm not going to use black the diagram i showed you at the start of the presentation
which was seen on a AM2 pre-assessment day they use black as their neutral now if the wiring
diagram you're given is black as neutral with over sleeving blue so in other words you'll have to put
some blue sleeving on here the um that's fine but i'm not i'm going to use my grey one so this makes
my drawing more unique to me and i'm going to use my black as one of my strapper conductors so this
grey conductor here will have sleeving on it which is blue in order to identify it as a neutral these
two here will be my strappers and my CPC so we'll have our two strappers from here coming across
we'll have a neutral coming across and being left in this box and the CPC as well so we're
bringing the feed through the switch okay so we're coming through with this neutral is going to keep
linking through so let's bring those in next let's start off with the gray so i'll take my grey pen
to my gray of my three core i'm going to make my neutral and i'm going to take it out and through
so let's bring it down here in my 3 core and again i'm going to need to leave it inside a connector
but i'm going to need to identify at both ends so i'm going to need to put some blue sleeving on it
so i'm going to pull that my neutral so in order to do so i put my blue sleeve in on it so that's
my neutral of my three core being brought through two strappers now again it doesn't
matter which way around we are here uh whether we use um brown and black for each one so it
doesn't matter which one we go in okay so i'm going to bring one across and then one across
so let's try and do that the easiest way we can let's start off let's bring the black one
now three core across and we're going to go into there
and we're going to bring our brown one across and we're going to there so what we've got now
is these two here being used as our strappers but again because this is a switching line conductor
and i've chosen that one as my one we're going to need to put the over sleeve in brown we've
got oversleeve in blue here so we're going to over sleeve the ends of my black conductor
like so so that's identified as our strapper along with this one we've just gotta bring a
CPC across now so in case of bringing my CPC across as well into there within my cable
you'll have more chance of maybe making a neater job of your cable lines okay then i have so there
we go so we've brought switch strapper okay one of our switching line conductors this is
our strapper one of our switching line conductors and this one here which i've used as my neutral
and i've identified it accordingly and again it goes into a connector so all we've got to
do now is bring another three-core cable through into this switch same process i need a neutral
to appear in here and i need two strappers from here and here to appear in here as well
again i've said it in other videos if we come out of here with the three core black it just
matches it doesn't matter if that was the brown and that one was the black but generally when we
do connections and drawings we like them to match but it wouldn't matter if those were the opposite
way around but as long as the cable with the black and the brown goes in the bottom two and one in
the top two and not across the sides okay that's a common fault that is so let's start by using
my grey from the grey pen so i'm gonna bring my grey through and i'm gonna jettison in here so
bring my grey down of the three core and i'm going to leave it inside here again in a connector let's
make that connector like so and now i need to identify remember this grey is our neutral for me
okay so i'm going to put blue sleeving on it remember to look at the wiring diagram you're
given if someone says they're using black fair enough you need to identify the black with blue
sleeving but i've used the grey of the three core for my system here because that's how i wire right
so now we've got to bring our other conductors in and i've got to try and make the best job without
crossing over so if i bring that one over and then that one round there trying to make it as neat as
i possibly can so let's start by doing let's do the black one so we've got to bring that round
and i'm going to bring it into there again because that is a switching line conductor
identify it with brown sleeving at both ends i now bring my brown through
like serve my three core into there
and now i've got my CPC to bring through so bring my CPC through like so okay there we go
so now we've brought a three core here from our intermediate switch out again but this
time we've got a strapper and a strapper our switching conductors here our strappers
and a grey neutral identified and left in a connector okay as we bring this uh wiring system
wired through the switch which they're calling it AM2 so we'll wire through the switch for this one
now we've got to just make sure that we can turn this lighting point on this lighting point will
need a CPC it will need a neutral and it will need effectively a switching line out of the
common here so that's next so we're only going to bring up our standard twin and CPC cable so we're
going to bring our blue neutral out the connector our CPC connection out of the back of the box and
our switching line conductor out of the common terminal here so that's next so let's bring those
around let's start off let's bring our CPC up and in from our cable interesting method this one
isn't it wired through the switch it's probably something you've not come across on site but if
you've got a wiring diagram you should be able to cope with the actual connections required let's
bring our neutral out of our block like so i'm just simulating a lighting point here could be a
down light it could be a ceiling rose and pendant you've just got to obviously put the neutral the
CPC and now the switching line connection in here so let's bring this one out of here
into here so that's our twin and CPC brought up switching line neutral and CPC and the appropriate
connections made inside our lighting point let's move some of these bits out of the way
so we've taken the supply this time into our first two way switch we've come across with
a three core and across with our three core but out the end switch our last two way switch we've
actually come up to the lighting point meaning the neutral connection that we brought into switch
number one effectively our first two way switch had to be carried on and through the system
until we could get it up to our lighting point our permanent line came into common our two strappers
came across to our intermediate switch and then we had another three core cable that brought our
two strappers across to our second two way switch and then we took out a switching line
neutral out of a connector and our CPC connection up to our lighting point itself we go back to this
one here the wiring diagram that i managed to get hold of wired through the switch
supply comes in three core comes across three core comes across and we have a twin and CPC cable up
to our lighting point itself we have connectors for our neutrals in each of the three switches
this one also showed connectors for the CPC's maybe there wasn't an earth terminal in the back
of the box all the videos i produce to try and help you obviously become an electrician
or progress onto an apprenticeship etc you've always got to remember you've got to master
all the elements so i've suggested that this one might be currently being used AM2 and AM2S
where you take the feed through the switch but they could change it so you might find
it's three plate you might find it's two plate look at the wiring diagram if you've got one or
you have to construct your own use the knowledge you've obtained from college and on site in order
to master the elements required for your end point assessment i always recommend you do the um ends
point assessment pre-day or pre-days maybe they do it over two days well you go there and they will
help you familiarize you with some of the skills required in order to tackle
your AM2 AM2S and AM2E so this video here hopefully gives you a standalone video
which is the taking the feed through the switch a system that they may be using at AM2 and AM2S
however it would be a nice one for you to also master because this is another way of which we
can wire two way and intermediate switching where we bring the feed into the first switch
we bring our three core across which actually brings a neutral round and then we take a
twin and CPC cable up to our lighting point as always i hope this video has been some help you
