in this video we're going to continue on a series of videos looking at steel conduit and what we've
got planned for us today Jake so we'll look at a range of fixings and the common accessories
that we usually see and they're all behind us on the bench yeah should we take a look
where should we start got a lot of items to get through but i'm focusing on this one down here
what we've got here so that's a crumpet Gaz so how's that going to work then so we'll use that
where we know conduit is going to be chased in so we'll just hammer that into the wall like
that chased into a breeze block or hammer that into mortar and that secures the conduit and
then obviously just plaster back over the top of it that's right yeah okay so we're looking
at fixings let's go for this one here which is a bit unusual not many times i've seen one of these
yeah that's a one whole plain saddle and where would i use that so we might use that in locations
where we know that the conduit is going to be plaster boarded over and not going to be seen so
quick fixing for the electrician but obviously no access there for once it's installed that's right
so the next one too that's also a plain saddle isn't it yeah that's a two hole plain saddle
and again for smooth surfaces smooth surfaces yep okay the one at the back here is probably
the most common one to me when i was training and that's the spacer bar saddle when would i
actually require a spacer bar saddle so we use it on brickwork and uh we've got one fixing hole
and we don't need to remove those screws we'll just slide that up okay and there's one fixing
and then drops it back on and then we tighten that one off that's right the common saddle now
you see on site a lot is this one at the front here what is that that's a distance saddle and
why we moved over to more distant saddles maybe than we have before so we're using these more now
to avoid us doing more sets or dogs legs as we might call them a piece of conduit will line up
perfectly with that knockout in that socket there so if i bring this one forward those holes will
line up oh yeah they do don't they so therefore no little sets if i was to replace that with the
traditional spacer bar saddle we've got at the back does that mean i'd have to make a little
set in there you would yeah let's bring that one in and take that one out of the way let's see if i
can see us oh yeah you can already tell can't you that yeah it doesn't get it in the right position
and then finally this this really big one back here what's this yep so that's a hospital saddle
and obviously the first thing you're going to think of it's used in hospitals that's
not true is it no it's uh it's used in we use this in high hygiene areas so
maybe some areas of hospitals canteens etc and we've got a piece of conduit in that
that allows that to be easily cleaned behind
ah right okay so that that bridging it off the surface even more means a cloth can get under
the back side of it as well as obviously all the other sides to clean it oh i like thinking that
so that's the saddles and the crampet uh dealt with got some more of our traditional boxes
here which one would you like to start with so we'll start with this one so this is a u-box
and i can see we've got a couple of threaded spouts and two holes in here yeah what's the
thinking behind all of these boxes having threaded spouts so that's pre pre threaded so we can to
take our threaded and our conduit straight into that so you just obviously simply thread
the conduit and attach it to the box itself yep i like that and what size are these holes here are
these 3.5 as we would see perhaps traditionally as a socket front screw no these are pre-tapped
for M4 screws ah right okay so the M4 screws in order to hold things like boxing it's on etcetera
so that's that one what's the one next to it it's going to be controversial i would imagine maybe
so we've got a y box there okay is there anything else you might want to call that one some people
might call that a trouser box okay yeah so that's what i called it when i was on site
moving backwards and we've got an intersection box there really is that what you call it that's
not what i'd call it i'd call that 4 away box okay so we'd like your comments below if you call these
anything different on site obviously i would have called that a four way box on site but you called
it in the first place yeah an intersection box an intersection box right okay so what's this one so
this is a terminal box is it not an end box not an end box it could be an end box if you want uh
end box or a terminal box yeah and then obviously one well i don't think there'll be any controversy
over this one no that's a through box okay and then we've got some couplers is that right we've
got some couplers these are 25 more couples we've got here and we've got a 20 no one here obviously
those are all in the size can you just remind me of the common conduit sizes yep we've got 16 20 20
25 and 32 okay and the coupler would be threaded on to the conduit itself that's correct and then
we'd use this thing at the back here would we to attach it maybe to a box yep so that's a male
brass bush okay and they do do female bushes as well don't you yeah so that's some of the common
fixings and boxes that we'd expect to see in the electrical industry say i was an apprentice are
these the sort of things that they could ask some multi choice questions by showing you a picture
of any of these this could definitely come up on a multi-choice exam yeah so we've looked at
a common range of fixing and accessories here Gaz the range we've just looked at is galvanized steel
in high hydrogen areas with normally see stainless steel being used ah that makes sense so alongside
that hospital saddle and talking about high hygiene it's like to be a stainless steel
saddle and conduit in those places we're going to go on in the next video and look at some
of the accessories that even we weren't too familiar with when we got them out of the box
and we're going to name those as well as start in the process of looking at this stocks and
dies leading to another video where Jake's going to produce the perfect thread onto a piece of
steel conduit as always we're interested in your comments and your feedback so if you've called
these boxes something different on site please leave those below and if there's anything else
you want us to tackle in this series again leave those comments and we'll try and make
those videos as well Jake's gonna as always get back to as many of those comments as he can
