so we're here at the Elex show and we're with Paul from Hager so we're really excited because
we're going to talk about a very specific product which is this consumer unit so bring the camera in
Gaz and we'll have a look at this so whole just explain to me what's beautiful new and unique
about this Hager consumer unit so we do this consumer unit it now that's pre fitted with a
type 2 surge protection device so as far as the installer has to concern himself we fit in this
it's nothing so all he does is what is that going circuits like we did before you can see the surge
protection is literally wired from the bottom of the main switch so we don't need any overcurrent
protection device in here either so it's wired from there simply line a neutral to the top the
surge protection and the earth going away to the earth are absolutely fantastic surge protection
you notice it's got this green window so as it sees surges this part of the surge
protection device will eventually wear down and at some point in future that window could be red
yeah should that window be read simply all the customers had to do is pull this cartridge out
oh wow get a new cartridge and simply put it's that simple just let's move that and yet just
goes back in again and I've not done this before on a Hager board so let's see and that's it and
that simple as that fantastic ice object right now obviously surge is a big kind of discussion
with the industry industry at the moment and there's all kinds of you know sort of feelings
flapping around about this but what I love about this is the fact that the decisions made for you
just by this board yeah all the calculations have been done it's all in the place you don't have to
worry about it and also because of the way that this is mounted within them we're falling within
that half meter the half a meter counts from this space here so the line conductor to it plus the
earth away to the earth bar those two combined distances would hopefully be under half a meter
and you can see we're under well under half a meter so Paul it looks here like this doesn't
have a circuit protective device on it there's no circuit breaker on here is that necessary not with
this device actually some manufacturers require some don't because there's internal protection
in this particular surge protection device so it is a parallel device it doesn't have to it's not
carrying current so it's literally sitting across the line and earth and as a spike comes into the
installation which could go through the equipment of course and damage your electronic equipment
your house this will momentarily switch down to earth extremely fast of course and dissipate that
surge to earth well when it going through the installation that fantastic so we're not worried
about that getting overloaded as we would do a conventional circuit it's not carrying current
at all the only carries the surge current it doesn't carry normal okay brilliant thank you
for clarifying so for another really great thing about this consumer unit that we're looking at
here as we said we call in this an 18th edition board we've got the surge protection built in
but what's the advantage as well with this RCD what have we got going on here the 18th
edition brought in two requirements for the RCD in a split load consumer unit like this one the
installer must take account or have knowledge of the type of loads connected from the RCD we know
now that a lot of electronic equipment fed in a standard house can generate pulsating DC faults
or residual currents so you will notice the RCD is now a type A which is a specific type
that can detect these pulsating DC as well as AC type rcds fantastic so if this wasn't
an a-type there's a potential that this could be almost stunned by the DC leakage current s in CA
correct and it wouldn't trip on the earth fault and earth fault conditions so now by putting in
an a-type RCD were overcoming up yes we are yeah just the absolutely brilliant I love this kind
of forward thinking that Hagar demonstrated here absolutely brilliant it's well there's one other
further point actually in in the 18th edition it told us to make a consideration for overload
protection of this type of device as well this is the only type of device we use today that
won't trip as over current going through it so what we have to do is either consider how many
amps could be run from the RCD yeah in which case you know these wouldn't add up to morning the RCD
right all what we've done a Hager is actually default to the maximum current for the consumer
it's only 100 amps so you know it's also 100 amp all right so so 100 amp RCD so you can
never draw more current through here then we can connect up to to the board anyway what of what
just it's little details like that that just make all the difference on installation so yeah really
beautiful work what a great bit of kit thank you very much for introducing this to that ok
so I'd love to play certain items to select a stake here at the election hundred houses Alvin
came out sources said it ought to end the video sorry Aaron we got a video has been some help
