so we're back in the world of cable containment today and we've got something special in the shape
of this ip55 salamandre distribution trunking from Legrand this is what the Meccano of trunking
however you've picked up a trunking machine in a previous video we got there gordon yeah
so i've got the other version of the salamander trunking it's this ip4x version we have made a
video about this i'll put a description either in the eye above my head or in the description below
i'd suggest this is probably a go-to trunking for a lot of regular installations because it
is incredibly easy to install it's got some great design features in there however we're stepping up
a gear in terms of the ip rating today with this ip55 version okay so let's start by refreshing
ourselves what ip55 is going to give us as a protection level so let's have a look here
so if we look at the first number the five that's going to give us protection gordon up against
yeah so yeah sealed against ingress of dust so the foreign bodies been in that case dust and
then if we look at the protection against water or moisture we've got jets of water for the other
fives that gives us our ip55 yeah and obviously by that that obviously gives us an indication
of where we'd possibly use it so we're thinking some external or partially external applications
thinking of applications car parks rooftops and canopies some rail applications depots things
like that where you might be doing some cleaning or dust is a problem and let's remember electrical
installations have to last usually an incredibly a long amount of time so yeah dust can build up even
in yes systems like this where this probably steps in and more suitable for those applications and
we're going to see how it fits together to keep that ip rating later on in the presentation you
you touched on a nice couple of bits there and i know they've had it tested as well with salt water
being sprayed at it for a considerable amount of time do you remember how long that was yeah well
yeah 672 hours to be precise yeah it was um so yeah so this looks like yeah galvanized you know
just like this system here but it feels different dimensions yes it's not just not just galvanized
got a clear powder coating on top of it so i think powder coating is normally associated with paint
but also it's a clear finish and you can tell it when you feel it yeah yeah that's all funny let's
have a closer look then because there's some other nice bits that make it easier for electricians to
install so let's have a look at those ends shall we start off by looking at the fixings in the lid
okay so while the lid and where it fixes too that's probably thanks you've got these
flanged to fix to normally on the trunking that's turned in over yeah on this it's turned out over
for two reasons so it gives us incredible structural stability so that is pretty robust
yep and then obviously when it looks at our gasket to get that ip55 ceiling that's neoprene isn't
it yeah it's a neoprene gasket so that's going to make against that surface the inserts there for to
fix the lid onto are already held in place they're strongly held in place so you're not going to
just have a look at those so if we turn that over they're already yeah they're already what would
you suggest they're called yeah so they're captive bushes and obviously our screws that come with the
system just straight into there so there's no need for any threading or looking for nuts to
uh to fasten them to okay so yeah i like that so pre-punched holes in the lid we've already got
these captive sections here that we can actually screw down into in order to get that ip55 rated so
that's that's that's fantastic so we see how i put bits together now in order that we can
maintain that ip rate and then come back and look at the accessories closer yeah because there again
there's some subtle differences between the the regular trunking system and this higher ip rating
so let's look at the joining process it wouldn't matter if we were joining two lengths together in
this case we're joining to a 90 degree the process is exactly the same what have i got here then
gordon yes we've got a torx 25 security bit there so that's got the raised insert in the middle of
the screw head so you can't use a screwdriver if you if you were trying to remove it uh with that
yeah it makes it tamper proof doesn't it really so here we go
we've got our fixings here there's going to be six now i'm gonna have to come up with and i've got
some bolts in the packet that are 10 mil long for this so here they are so they're going to go in
there and then the other ones are for the lid that we'll come to later on it's the same screws across
the whole system so it's only one that one style screwdriver bit you need for that absolutely so we
go in here and you can see nice tight feel what is that material it's made of a neoprene gasket
yeah it is on maintaining that ip55 rating so i've got that into position and now i'm going
to just put those bolts back in place i have to tighten them up at the end i'm not going to do it
for this demonstration but what's the torque sent in they recommend for this so two newton meters
across the again across all these screw heads just to get the gasket to the right right level of
tightness to obviously keep moisture and dust out yeah so look at this just slide it into position
okay so i'm quite satisfied about doing that and then just repeat the process by inserting the
bolts once i've got all of those in we'll approach the earth continuity strap that lays in the center
there it is and that's going to use again the 10 mil bolts that we've seen previously just
pop them through the back making sure that we get those nice and tight as well so pop those in
and then we'll be looking at the lids next so in there go like so
just make sure we're nice and tight again it's going to be tightened at the end using
a torx screwdriver as you quite rightly said up to two newton meters of torque yeah you
can over tighten gaskets and that's when you can get yeah absolutely yeah so yeah
lids gone on and again now i'm gonna pop on the 90 degree section now that's not acceptable is it
no because then you need to put the again the cover strip over the top of the joints
yeah a couple of lid goes on this is a little bit longer now these are 16 mil
in order that we go through both yes it's going to go through the lid and the coupler
itself and into the body of the trunk yeah and four of those to go down obviously you
will replace all of them in order to get the ip55 returned to this salamander trunking
next we're going to have a look at actually inserting a hole for an accessory into it now
gordon yeah we're going to punch it out towards m25 hole here i'm going for a 20 this time so
i'll use the step drill to get me down to 12 mil and then i've decided to use a punch rather
than a standard hole saw it gives a lot cleaner edge and why is that so important when you're
maintaining ip ratings yes obviously the weakest part of the system is often yeah cable entries
gland entries things like that so yeah nice clean holes for any uh yeah cable glands other conduit
entries yeah and also i'm gonna get in there and deburr it this will give me a nice smooth finish
as well by using the punch so i think on one on both levels there and we've just got this neutral
i don't yes okay you would bring that up yeah i do like using it look at that super smooth
that's the the hole done okay i can just undo my accessory if i needed to but that's it
finished so look to some of the assembly but can we take a little closer look at some of the
accessories we've actually got down here we've got a few haven't we but yeah we've got a few but yeah
there is an extensive range so we've got yeah the angle uh 90 degree bend you showed in the in the
demo there gary here's an end cap so let's just have a look yeah spin it around because yeah so
again that flange goes all the way around there's the link to put the whole put our earth link in
but it is it's that coupling between them you always need one of these accessories that goes
around it yeah and that's what i showed so it wouldn't matter what i was linking together i'm
always going to be using these cupcakes i'm just going to be using one of them and you're always
going to have that cover plate that goes over the top yeah which again needs that slightly longer
screws because it's obviously got to go through three layers of metal to get into the into the
insert there okay yeah and then we've got one here we've got the one that's it may be on top
of a distribution board and we're getting some flange coupling as well but yeah i mean they're
going to an extensive range you know all the all the bits you'd expect to see the trunking range
all the various angles you can also do this in two and three compartment variants as well um
and it comes as standard as two meter lengths so a little bit shorter than you'd have in the the
regular trunking and also comes in sizes we've got the 50 by 50 here but it goes all the way up to
225 by 225 as well yeah and that's the internals obviously that doesn't include the flange on the
outside as well so yeah that's it's a nice well thought out range yeah it is pretty easy to put
together it is and this is where we really would like your thoughts on it have you fitted it before
that would help us so you can give us some you know people in the community can then see
other applications of where you've installed it is there any real tricks and tips you'd like to
give the community could you leave those in the comments for us below or is it something you're
thinking about fitting in the future again we'd love to hear from you and so would legrand we
love the salamander range if you haven't checked out the previous video i recommend you do so
it's got a lot of great features that make electricians life easier and we like that at efix
