we've made a couple of videos here on efixx now regarding dado trunking and some of the
regulations that electricians need to think about when working with it in this video we're going to
zoom in on the dado trunking itself and look at some of the features and innovations that are
included in this excellent Marco Elite Compact dado trunking from Atkore first of all i'm sure
you'd agree it just looks great doesn't it it's got this lovely curving lid at the top and the
bottom it's a three compartment trunking meaning that you've got space for mains cables going
through the middle here perhaps data in the top section and maybe other telecommunications in the
bottom or even safety systems that might require segregating but what other features does it boast
well it's available in the pure white finish that we've got here it's also available in light gray
or charcoal finishes meaning that it can be used in different ways to comply with dda requirements
and it can also come with an antimicrobial finish as well which is really reassuring in these days
of global pandemics one of the things i love about this product is how much thoughts got into making
it easy for the electrician to install let me give you just three examples here number one the back
is pre-punched with slotted holes every 200 mil to allow for easy mounting and to allow for a little
bit of easy adjustment after fixing number two of course even when we're running data cable in
the top section we still need to drop through the separating barriers here and to make that easier
there are these little pre-punched knockouts every 150 mil and they can simply just be pressed out
and the cable passed through to the waiting enclosure beneath and finally number three and
this is so simple but just absolute genius if you look at the bottom compartment here it's always
a bit of a pain to install cables in isn't it because you can end up trying to keep the cables
in with one hand and then put the lid on with the other and then get your hand back for future use
at some point after you've put the lid on however the lid on the elite compact is designed to
hinge on its bottom connection and leave a gap here that you can install cables into and the lid
will support the cables before closing it up it's so much better than trying to wedge in bits of
cardboard or little sections of lid that need to come off as the final lid goes on and if you
look closely at the way that bottom clip is molded you can see how it achieves this by leaving a gap
between the clip on the lid and the corresponding section on the base absolute genius i really like
that but of course when you're working with dado trunking it's as much about the accessories as it
is the trunking itself the external and internal 90 degree bends come in two parts which means
that they can be adjusted just in case the walls that you're taking the trunking around are not
perfectly square looking at the flat angle and t connectors you can see some further nice features
in the right angle here the separating partitions continue around the bend to maintain segregation
of different voltage bands and are molded in such a way that any cables installed can maintain the
correct bending radius and that includes data cables such as cat6 and 6a cable and you can do
the same in the t-junction as well and speaking of that t-junction there's a piece that sits
inside here and maintains the segregation where the cables may need to cross over each other
to get to the right compartment you can see the cables can run over and under there and
then when the lid goes on it just overlaps the lid it just clips into place here and you can see that
that overlap means that you don't have to have additional joints between the connectors and the
trunking which gives a neat smooth professional looking finish some nice optional extras to
look at now first of all you've got this steel screen divider that sits in the trunking here
between the sections and helps to reduce electromagnetic interference between mains and
data cables and again we see that great thought process of making electricians lives easier
it's pre-punched with holes that line up with the knockouts in the trunking and these can just be
bent out and snapped off giving easy access for the data cables to drop into boxes in the main
section and it also has these connection tabs here that can just be bent up and the right type of
crimp pressed on to make a good earth connection another nice accessory is the takeoff adapter
that allows you to connect a piece of conduit or mini trunking to the dado system neatly and easily
this flat section on top can be drilled giving a solid connection point for a conduit adapter
or if you look inside here you can see there's guides for cutting out so that it sits around
different sizes of mini trunking and then that simply clips onto the top there allowing access
for trunking or conduit and then finally there's this RCD din rail kit this metal part here this
just sits in the back of the dado trunking there and then you've got a choice of two frames to sit
over it so that just clips on nice and easily and then you can connect an outgoing circuit
and pop the lid on so that would be perfect for something like a laboratory or maybe an
educational installation i'm sure you'll agree that the Marco Elite Compact trunking system from
Atkore is great looking innovative and adaptable and it's made in the uk in short it's the trunking
system you should probably be using on your next installation thank you very much for watching
you
