hello and welcome to this electrical
principles training video no not on this
occasion i know this may come as a
terrible surprise to some of you but i'm
actually doing some electrical
installation work and there's not a
calculator in sight for once but i just
suddenly had a little bit of an
inspiration i'm doing some work on the
lighting in this property making some
modifications to the way it's working
because a wall has been taken down and
turned a room into one big kitchen diner
effectively but uh what i wanted to just
talk about it was quite interesting it
suddenly struck me that um i was holding
in my hand something that's very
important to
electricians and when you're doing your
installation work on site you'll come
across these
these are dry lining boxes or
plasterboard boxes now what's quite
interesting is that when i started out
my electrical career i was actually
working with this brand here this is
called faster fix to the point where for
about i don't know five years or so at
the start of my career i thought that
these every single one of these was
called a faster fix box but it's not
that's actually the brand name here
and it struck me as interesting because
that's quite a simple piece of kit it's
a dry lining box it goes in the wall
i'll demonstrate that in a minute you
pop the
little tabs in push them into the wall
and when you do up the screws onto the
front plate whether it be a switch or a
socket or whatever it pulls the box uh
tighten up against the accessory and
kind of sandwiches the plasterboard in
there and that's what stops it from
falling out or falling in but it's just
something struck me that actually i took
another switch out from a wall that's
gone now and in that wall i found this
box here and actually i've never
come across this particular type of box
before
the only branding i can see on the
inside of here is ega
uk so i don't know if that's part of the
eager tube i'm not sure but it just
struck me as interesting because i've
never seen this style of fixing before
either
i'm going to knit back to the studio a
little bit later and i'll show you
another type of
fixing box in the side of a dry lining
box but this one is is kind of uh sprung
inside there and when you push this in
it will kind of deflect like that and
then snap back out again and hold in
place and again when you do the screws
up it will grip against the front there
and it just is interesting that there's
kind of a nice kind of almost story here
that you know this is the the brand of
box that i started out my career with
but even
many decades into that i'm still finding
new things and learning new things about
the electrical industry that i've not
come across before so even something as
simple as a single dry lining box uh is
something that um
uh yeah there's still surprises to be
had there and i just thought that was
quite interesting what i'm gonna do i'm
gonna fit the the faster fix box for old
time's sake so i'm gonna put that in
here so what i'll do is i'll i'll just
knit back to the studio and i'll show
you
the other type of box that i'm very
familiar with and i'm sure you'll be
familiar with and another type of lug
that goes in there and then we'll knit
back and we'll actually fix this in here
and i'll show you how it works
okay so we're back at the studio now and
just having a look at this third type of
plasterboard fixing box here again
there's lots of others available this
one is an appleby one and this is fairly
common actually you'll see this in an
awful lot of different places exactly
the same principle but just a slightly
different method if we just look here
you can see
that the side fixings there the lugs are
designed just to snap into place in this
one so you can push the box in quite
easily because there's no lugs sticking
out at the side to start with but then
once you've got it into the plasterboard
it's just a matter of
pushing that in and pulling it forward
and the same on the other side and then
you can see there that when you do the
front screws up on the accessory it's
going to pull that lug there tight
against the plasterboard which will be
sat there and that will make that
a really nice strong
fixing inside there so again just
another type of fixing and again there's
still others manufacturers have used all
kinds of clever little tricks
to achieve the same effect so yeah so
let's just head back over to
the job that we're on and have a look at
actually popping that plasterboard box
in
okay so as we said i'm going to pop the
faster fix box in the brand faster fix
that is of course it's a dry lining box
and we're just going to pop that in
there like that bring the cables through
this knock out of the top that's already
been knocked out there's another
knockout at the bottom that i could have
used but i don't want to make a hole if
i don't need it and that just sits into
the hole that you've cut in there and
then all you've got to do is with these
ones they've got these kind of sprung
clips that go in so there's a little nib
there so if i just pop the spring onto
the nib and then push it in
and outwards like that you can see that
what that's trying to do now is it's
trying to push back against the
plasterboard and actually grip against
the plasterboard so if i do the same
thing on this side so again there's the
little nib pop the spring that you can
see there
onto the nib and then push that in and
that's going to hold that and what i
really like about these fast fix brand
ones is that you've got this
kind of spike on there which means that
when you do it up when you put the screw
in the front there that actually kind of
gets dragged into the plasterboard and
gives a really really uh secure fixing
against it so it gives you a nice firm
uh mounting position so we'll just pop
that there
drag that forward a little bit just make
sure it's firmly in place and it's just
a matter of terminating it
in the front on and that'll screw up
against there and grip that really nice
and tightly so there we go there's lots
of different kinds of dry lining boxes
out there lots of different brands on
the market
and again you know they've all got the
different benefits and uses but it's
just a nice little trip down memory lane
for me to be able to fit a faster fixed
box like i was all those years ago thank
you very much for watching
oh it's a gsh video sorry we hope this
video has been some help
you
