hello and welcome to this latest in a series of videos that we're producing on the subject of
trunking we have the great pleasure of having lecturer Jake with us again thank you thank
you for joining us mate what are we actually going to be covering in this video Jake so in a
previous video we've looked at putting more common accessories together we looked at the flat 90s and
the internal and external in this video we're going to look at the more complicated ones tee
offsets and reducers as well fantastic so what we're going to do is we're going to bring the
camera in nice and close and we're going to have a so we'll take a look at a tee now Joe but this
time we're going to look at the the different size trunking 100 millimetre by 50 millimetres
it's a different size but it's exactly the same slots together just as the 50x50 did
there we go screw that together now very good so it's nice to see this slightly different size of
trunking so again if you working at a college or you learnt in a college then normally 50
by 50 is sort of the standard that we always work with so it's nice to see just something
a little bit different it's all the same principles just a slightly larger size
if i can get the screws in jar this is reality sometimes screws get dropped one of the best
pieces of advice that anyone ever gave me about working on sites is when you drop a screw on
the floor it always bounces in the opposite direction to what you think and that is a guiding
principle that i've lived my life about usually bounces about a mile away as well absolutely
so
there we go so those those horizontal sections connected up and again it
couldn't be simpler could it that's right just a vertical part now to fix together
yep so that just slides in nice and easy
good and again we've seen the benefit of this type of trunking so this is the fast fix trunking from
Atkor and we're really seeing the benefit of that raised lip there on the inside of the accessory
because it very simply just gives you a point to push the trunking up to and you know that
you're always going to be somewhere in the right position which is good
happy days look at that fast fix indeed so again we'll snap some lid on as an example and it's just
worth seeing there Jake over on that side you've got a different number of screws to what you'd
have on the 50 by 50. that's right yeah that just had one on this side of trunk and we've got two
screws very good could we just have a look at the other side of that lid if that will come off nice
and easy so again it's the same accessories in the same turnbuckles that's right yeah you've just got
one at the top and one at the bottom so that's really good nice to see that and while we're
talking off camera he fitted that piece which was brilliant like a ninja and then we'll snap the
tee lid into place very good so again we've just left this upright piece off as a demonstration and
you can see there that just goes on really nice and easily now what's interesting is this is all
pretty much exactly the same as we've seen already but the accessories that we're going to be looking
at next have a slightly different fixing method for both the trunking and the lid but we'll get
to that in a moment so where would we sort of see this being used Jake so a bit similar to when we
looked at the flat 90 in a previous video really where we need to change direction so we're running
along a wall we need to drop down but also in this case we want to continue the trunking further as
well very good so if we're dropping down to some accessories or a consumer unit or something like
that then that would be brilliant and of course we can also use it the other way we can come
down with a single piece of trunking and then we can use that to lead to a horizontal piece
at a lower level fantastic really good okay so that's great we'll move on to our next accessory
so we'll take a look at an offset now Joe using the 50x50 trunking very nice okay so an offset
so what's the principle here what does this do for us yep so if we're running trunking along a wall
like so and we need to overcome an object we can use an offset to get around that and then
another one to set back to the wall again very nice so it's anywhere there's a change in level
of the wall or a change in perhaps height in a ceiling that's right yeah good stuff so a little
bit different to the other ones it doesn't just slide in we've got to use a coupler for these ones
so the coupler will go between both very nice and this particular accessory again from Atkor that
comes with the coupler inside the offset accessory there as well right yeah very good excellent so
you don't have to worry about ordering separate couplers for these they come in a one so we've
just got four screws per side now very nice very good and of course again we've got the benefit of
the pre-drilled hole in the accessory and then the hope for the best hole that we've built
excellent yeah so it's interesting so there's again this these two different types of fixing
method that Atkor have used here um and this is uh yeah the use of the coupler so there's those
extra screws but again this is actually how most manufacturers produce their trunking with the need
for a coupler for these things so actually the fact that core have got those accessories that
don't need a coupler and that have that snap on lid really does show the benefit of that range
that's good so that's that side popped on already and again we can see inside there we've got that
coupler hiding away just sliding out ready to get into view excellent
just slide that over the couple same as last time making sure both all them holes meet up very good
excellent again it all comes down to how accurate your drilling is
and i think we've mentioned a couple of times that uh we've used the idea of a template from
Eddie from Pegasus electrical demonstrated that to us and we're showing it to you now so thank
you all we did in the previous video i should say so we thank Eddie for for doing that because that
saved us a lot of time in the making of this series of videos which has been brilliant we
can be sure it'll save you time as well so if you're not sure what we're talking about please
do go and check out the video where we describe that template that you can use for your trunking
very good
nice
so there we go that is the coupler attached and then when we draw back and look at that again
you can start to appreciate what we're looking at there you can see that change in height that it
facilitates for the trunking there which is really good anything just to think about that's slightly
different with the lid here Jake yeah so we'll put the lid on so i'll just lid on the trunking first
very good so as we said i mentioned earlier it's not um quite the same as the other pieces we view
so it doesn't just snap on this time we've got the turnbuckles on the lid as well very good
make sure we get the lid the right way around oh it's critical yeah very important good stuff
excellent and that's just a sort of a quarter turn for those turnbuckles yeah
very nice and that holds that in place now i can't help but notice Jake despite your
excellent craftsmanship here uh there is a little gap between those two so is there any
kind of accessory we can put on there to help us with that situation there is yeah we've got
some joint covers that just snap on over there to maintain the IP rating of IP4X good stuff let's
just cut to that footage now so as you said Joe even though i've cut this piece of lid expertly
we still have a slight gap with it being a different type of lid not being the snap on type
very good i like that modesty doesn't prevent you from saying you did that expertly so that's
good so show us how this works then Jake so yeah obviously top of an enclosure IP rating must be
IP4X minimum so these joint covers help us to keep that snaps on nice and simple and that really does
again however expertly you've cut that lid you're never going to get that gap absolutely perfect so
that also just helps to hide any kind of unsightly gap between the lids there really good like that
okay then Jake so once again we've got laid out on the bench here what looks like one of those
exploded diagrams from a Swedish flat pack furniture retailer so what's going on here
yeah so we've got a reducer Joe or perhaps an enlarger just depends on your mindset
yeah absolutely so this um as the just same as the last one we've looked at you need your couplers
for this one it doesn't just slot together oh okay right so we've got that situation again
coupler between yeah and again looking at the lid over on the right there i can see the telltale
heads of the turnbuckles there which means that we've got the slightly different method of fixing
that's right so i'll just line that up again get these screws in this side first very nice again
Jake's taking a brave pill because we're not using pre-drilled manufacturer holes on our trunking
so he's very confident in himself being able to drill those accurately and i think it's been
validated in that belief through the course of this series of videos
look how perfectly that one's lining up as well absolutely beautiful there we go so that's this
side done now over on the other side Jake that little coupler you put in that's not gonna
fit over there so what's the solution on this side the larger coupler
this side to fit the 100 by 50 trunking excellent so you've got a coupler the same size as the
trunking that's going to bridge that gap for us and bring that straight into the trunking together
very good so once again we've got that neatly lined up and it's just a matter of popping those
screws in and joining those together now so far in this series of videos we haven't discussed the
subject of earth straps and we haven't installed any so we're deeply curious to know what your
thoughts are on that so as you're watching this video and you're thinking about trunking feel free
to comment on the use of earth straps necessary unnecessary do you need them sometimes and not
other times please let us know what your thoughts are in the comments section below
nice so that's all of those screws done up nice and tight and those separate pieces of trunking
have now become one continuous system and again where would we think about using this Jake why
would we need to use a reducer like this so it might be as we're coming into a distribution
board something like that yep so it may be that perhaps we've already branched off further on
the left there where you've got the the larger trunking lots of cables have already disappeared
out of here and economically speaking there's no point continuing that 50 by 100 trunking any
further because you've got less cables going through here maybe yeah that's right makes
perfect sense so i'll pop the pop the lid on the trunking first and again we're just resting the
lid on in this case just to demonstrate how this goes together and then we put the face plate on
for the reducer so again it's a lid with the turn buckles in it's not a snap on lid
very good turn those now get this lid on so just those 90 degree turns and again sometimes you
wrestle with these they can be a little bit tricky sometimes to get in place and in this
case they're snapping on really nice and easily and there you go as we draw back you can see how
that all fits together to leave you with a nice neat compact enclosure there which is
absolutely brilliant so there's our three accessories for this video thanks very much joey
so there we go those are the three accessories that we wanted to take a quick look at in this
video so just remind us what they were Jake yes so we looked at tee reducers and offsets too
happy days and i'm not talking about the american wrapper offset from the group Migos that's a
different type of offset that's good because my mind was definitely going down that road
thank you for once again highlighting the vast difference in our ages there Jake much appreciated
so if you'd like to comment on anything that we've looked at in this video if you think that we've
missed a trick somewhere if there's another type of device or accessory that you think you'd like
to feature in this series of videos or even if you have strong opinions on the uber of
Migos negotiating Migos then also please feel free to comment on that below i suspect we're not going
to get many of them Jake okay but as always we want to hear from you so please leave all of those
questions and thoughts in the comments section below and Jake promises faithfully that he's
going to get back to every single one of those so make the questions as hard as you possibly can and
as always all that remains to say in this video thank you very much for watching that is my line
