in a previous video in this series of videos on steel conduit we looked at saddles and some
of those common boxes that we're likely to be fitting on site we've got plan for us today Jake
so we're going to take a look at some less common fixing and accessories which
i've set up behind us here should we take a look let's take a look
this is quite an extensive set of conduit accessories shall we start up in this top
corner here and what have we got yep so we've got an extension ring there so in other words we can
put on top of a standard box and extend it down there a little bit further in order to make our
electrical accessory connection that's right and underneath it and we've got a rubber gasket there
when would i need a rubber gasket when we're using um conduit outdoors to maintain an IP rating okay
and it goes in conjunction with the box lid here does it that's right we've got a box lid below
okay oh this is something i've seen for a long time other than the classroom what we've got here
that's a solid elbow a solid elbow and that normally has to be very close to a drawing
in point doesn't it that's right yeah and the next thing down looks just like a little piece
of threaded conduit yeah that's something you can make yourself but we've got a pre-made one there
that's a 20 mil nipple and then a video coming up we'll show you how we can use one of those
and what we've got in front of it and we've got a three-quarter inch to 20 millimetre adapter
okay so one of these is the old imperial measurement so that would be is that an inch
yeah and the other one being 20 mil yeah in order that we can couple together two different systems
should we go back to the back one here yeah so we've got an inspection tee there and why do we
class it as an inspection too i'll take it this plate on the front comes off doesn't it we can
remove that when drawing in cables to make our life a little bit easier uh so we're not looking
necessarily inspecting the area under here so we're not looking under here just to what the
cables would be ease of drawing in okay next one down we've got a ball and socket cover
right okay i've never seen one of these before you want to just take that and explain what that's for
so a little bit like a tilted down light if you imagine you've got a sloped roof
that will hang perfectly so your light drops straight down so if i was coming down a staircase
then with a conduit system and i wanted my light thing to hang straight rather than obviously at an
angle because of the ceiling yeah that ball joint in the section in the center allows that to happen
that's different i'd love to know if anyone's fitted though so please leave comments below if
you've ever fitted those what's next so we've got an extension uh intersection box there okay so you
just drop that on top of a standard box for me i think there's some standard boxes that we've
looked at before ah right so we can come straight off the top of a box that's already installed if
we wanted to continue a conduit system on without breaking into it is that right yeah that's right
that's really clever in it and they do all kinds of different ones are these this is just remind
what that one is that's a intersection box what else might you call that a four-way box yeah a
four-way box we saw that in a previous video and next one to it we've got a throwback outlet box
so conduits can come both obviously in the back through the threaded spout and
just straight through as well okay moving to the back section another one and we've got just
the back outlet box there okay so just one one position we can bring the conduit in in the back
in order to make those just remind me what size screws go into all of these four millimetre screws
yeah M4's right okay full explanation then Jake what's this yep so we've got an earth coupler
never used one of these before have you Gaz no i haven't that's why i asked you what it was used
for so again comments below have you ever used an earth coupler before when did you use it and why
did you use it because we're struggling a little bit even with a little bit of research to find out
when we might need to install one of those so i'd love a comment below on that something else
that looks a little bit more familiar in front of it yeah we've got a hook plate there and what
would we normally be hanging from that so we have light fittings from there on some jack chain maybe
yeah okay and then in front of that we've got an extension angle box so similar to what we saw here
yeah but again just having an angled version of that box we come to the back and we've got a male
hook and again what would we like it to be hanging from there yeah just similar to the hook plate
we could go straight into a coupler with that until piece of conduit and hang our
light fittings from there yeah okay wow yeah okay love the look of that especially for a trainee so
there's already a bent piece for me yeah we've got a solid bend there pre-made bend and in there ah
so it's pre threaded as well ah so exactly the same as a spouted box you just screw obviously
your conduit in and you've got a bend already formed for you yeah seems too easy that one
we've got a flanged coupler there okay a flange coupler ah right okay so a bush and flange coupler
again if you've used these regularly on site explain to us why you've used those other other
conduit methods such as couplers and male bushes and similar to the others we've looked at we've
got an angled back outlet box okay and just here we've got a one whole looping box okay so that's
where your conduit systems may be into the poured concrete ceiling and you can have these with two
three and four holes in the back that's right yeah to bring multiple conduits in we've got an
uh inspection bend okay so similar to what we saw before with the tee so the idea being not
necessary to inspect the small amount of cables under there but that's a drawing in point that's
right and again are these threaded they are yeah okay now we've looked at saddles in a previous
video so what we've got this saddle for me yep so we've got a rapid saddle here so it's a quick fix
alternative to its counterpart here so again don't need to set that screw fully out loosen that off
and that will just drop and sit on its hinge we can actually you can actually sit your conduit
in there as you're installing so for horizontal runs that's perfect so that's only got the the one
screw obviously to hold it on and one at the back slightly different than a standard conventional
spacer bar saddle which has two screws and one at the back i do like that we've used them before as
well and we've got here and we've got an angle box but that's a tangent angle box so tangent
meaning we've got it right to its extremities so they do this with all kinds of boxes to
make them tangent ones what's the advantage of using a tangent box using a tangent box we can
remain close to the ceiling uh conduit can remain in the corner of the ceiling or the walls right
yes so pushing it closer to that ceiling and that internal wall or external wall yeah i like that
right cutting compound that probably leads to where we're going next
yep so we've got a tin of cutting compound here this is what i would use this is something you
might have used back in your day Gaz i've never used this before right that's isn't that made from
animal fat is that right beef dripping yeah okay that's beef dripping and it used to come up as
an exam question when i first started teaching almost 20 years ago tallow was obviously the
one thing that they could suggest to use as a cutting compound obviously we use a synthetic
one now don't we so if we open that one up that's our more traditional tin of cutting compound but
it could have been an animal fat in the form of tallow so if we've got to the cutting compound
obviously i think next we're going to be looking at threading conduit should we have a look at the
set for the stocks and dies in yep let's take a look so unlike colleges probably where they're
on a shadow board this is a set for our conduit stocks and dies let's have a look inside the box
ah right pristine condition could you build this up and talk me through the parts of this as if i
was perhaps going to thread 20 mil conduit yep so we've got stocks here we've got our handles
i'll insert them first they simply screw in what i generally used to call that whole thing
was the the stock even though it's obviously the stock and handles so that simply screws together
a lot of the case as well though we've then got our dies we've got 20 mil and 25 and the guides
to go with them as well oh right okay so there's a 20 20 mil and 25 mil um die there so under your
nuts these are handed now aren't they the dies when they go in you have to make sure you get them
right way around pop the guide in as well there we go so guide followed by they need to sit that
way so the nuts can screw down clamp down and how tight you do them that's it finger tight that's
just enough i think when people are training they tend to get a pair of grips on them and really
make them tight and actually that's not good it just needs to be firmly into position doesn't it
okay in order it sits in there and that's them built then yeah yeah so we would call that our
stocks and dies that's right so now that we've built these stocks and dies i think that's where
we should go next to take a look at threading some conduit okay so in this series we're going to
continue on on the next video we're going to look at putting a thread onto a piece of steel conduit
but again if there's anything you want us to do in this series of videos leave those comments below
and we've already asked you for applications of some of those accessories that are less common
in the electrical industry and as always Jake's going to try and get back to as many as he can
