- [Gary] I'm out on site and I've caught up with Eddie
from Pegasus Electrical and I'm looking at that panel, Eddie
and as a standard electrician, or what I suggest to myself,
I'm a little bit weak at the knees.
Are you gonna talk me through the basics of panel wiring?
Just to help me out?
- I can talk you through a little bit of it, yeah.
- [Gary] Okay. Was this panel built here on site
or was this built back in the, the vast factory
that is Pegasus Electrical?
- Yeah, we've built this offsite, so it's, it is all ready
when we come to site.
There's only a couple of things that need finishing off.
Only like the front switch, which we leave till afterwards.
Top tip.
Because if the wall isn't perfectly square,
then the switch won't line up
from the shaft to the front of the door.
- [Gary] Oh, that's a top tip.
Now we're in a boiler room, so this has got a whiff
of being some sort of heating control system,
is that correct?
- That's it, yeah.
- [Gary] So do you wanna just talk us through basically
what's on the front of the panel?
- Oh, we've got our switches, we've got these key switches.
So the clients who are not supposed to be messing with them
ain't gonna be turning them on and off.
We've got normal switches where they can turn it
from summer to winter and a
test lamp.
- [Gary] So just talk me through this one here then.
So what's the idea of having the the key switch then
on that section there?
- [Eddie] On this section here? - [Gary] Yep.
- [Eddie] It's, so it's where you put keyed off
into the auto position.
It's left there.
So if somebody don't switch it over to hand,
and then leaving it on hand,
or switching it to off and leaving it on off
when you want heat or not wanting heat.
- [Gary] So in other words, yeah,
another energy control system really
by taking it out of the--
- [Eddie] Yeah, just simple energy control.
- [Gary] Yeah, then we can whip 'round here
and just put it permanently on.
- Yeah.
- [Gary] Okay. Let's open it up and see the work of art
which is inside this panel.
It is quite breathtaking.
So just take a moment just to, exactly the same as I did.
Look at that. Fantastic.
Right, let's start on this side here. Okay.
Our old friend, the ferrule, jumps out at me there.
So class five conductors all ferruled up?
- [Eddie] Yes, and all numbered.
- [Gary] Okay. What's the thinking behind so many numbers
on so many conductors?
- [Eddie] Well, the numbering system is the schematic works,
so, and each, each cable or link of cables
will have a number and that will work in a certain order
and, and so, you'll get your drawings come together
with your panels.
- [Gary] Okay, so the drawings left with the customer?
- [Eddie] Yes, they're left with the drawings, yeah.
- [Gary] Do you keep a set yourself?
- Yeah, there's always a set itself, yeah.
- [Gary] Okay. So if I came to site and there was an issue,
I could look at those schematic drawing,
hopefully work out maybe number 24 and where it goes,
and maybe that'll indicate a pole switch has failed.
I can perhaps trace it through to obviously
use a logical approach.
I would suggest for many of us,
fault finding in here looks a little bit of a,
a headache and a nightmare, but the better
you've laid it out and the better the numbering system,
obviously the easier it will be to sort out a fault.
So any top tips in here?
So what's your, what's your go-to method
of installing the wiring system?
So if I look down here, at this section here, I can see
that our conductors are pretty logical there,
where we've got our protective conductor line
and neutrals together.
Have you not thought about putting
maybe a separate earth bar that we used to see
in distribution boards and consumer unit setting?
- [Eddie] No, I'd rather it this way because it, it,
it is logical that that CPC is for that particular,
either a piece of equipment or pump or boiler,
it runs with it.
So they're easy to find.
- [Gary] Yes. So if I was taking out, say a pump,
I would be taking out the line, the neutral,
and the protective conductor that are side-by-side,
rather than rooting around
trying to get to a protective conductor.
- [Eddie] Yeah. This associated with that piece of kit.
- [Gary] Okay. Any surge arresters in here?
- [Eddie] Yes, we've got an SPD
over the far right hand corner there,
next to the main switch.
- [Gary] And is that a type two surge arrester?
- [Eddie] Yes, it is, yeah.
- [Gary] Was that required or was that something
you was just putting in?
- [Eddie] Well, it is technically required now
because we've got PLCs and stuff like this in there
or logic controllers.
- [Gary] Have you put an indicator detector on that
at the moment or is that something
that maybe we could do in the future to have a failed
and a lamp will indicate?
- [Eddie] Oh, we have one on the front.
- [Gary] Okay. So if that lamp illuminates,
it suggests that the surge rest is beyond its life?
Yes?
- [Eddie] That's correct, yeah.
- [Gary] Okay. That's a nice little touch.
So again, somebody's coming in here thinking,
my heating system might not be working,
but it might just be that surge arresters expired its life.
What else have we got in here you want to highlight for us?
- [Eddie] Our contactors.
- [Gary] And what are these contactors doing?
- [Eddie] These are to the pumps and the solar valve.
- [Gary] And these are, by the looks of these,
they are class two conductors, are they?
- [Eddie] Yes.
- [Gary] Are we using any sort of crimps
on the end of those?
- [Eddie] Yeah, we use four crimps on these.
Ferrules as well.
So depending on whether it's the power side
or whether it's the control side.
- [Gary] But when we say ferrules,
that's class five conductors we'll be putting
those other crimps on the class twos, yes?
- [Eddie] Yeah.
- [Gary] And is that for a better electrical connection or
because it's easier to insert and remove those conductors?
What's your thinking behind that one?
- [Eddie] A better electrical connection.
- [Gary] Okay. Anything else you wanna highlight
in this panel for is?
It's a beautiful job.
It must have been Steve's work.
I always think it's your work,
but I had to move Steve out the way
in order to get into this panel.
- [Eddie] Yeah.
- [Gary] Overcurrent protection up here?
- [Eddie] Yeah, we've got overcurrent protection.
Also got auxiliaries on 'em,
which gives our faults on the, on the front of the panel.
- [Gary] Okay, just show me that please.
- [Eddie] You'll have your trip lights.
- [Gary] So this will indicate to me what has happened?
- [Eddie] The MCB, the overcurrent device has tripped.
- [Gary] Okay. So in real terms,
no one's gotta get into that panel without a skill level
because the front of the panel's gonna tell 'em everything
that's happening behind the panel?
- [Eddie] Yeah, theoretically,
if a phone call comes through to say,
"Oh, heating's not working."
We can say, "Well, what lights are lit up?"
If any lights at all.
And then we can work from that process
and we'll have an idea of what's occurring.
- [Gary] So there's a chance that Pegasus Electrical
can do the fault finding over the phone, open the panel up,
I expect it to be, say, top left hand corner.
I expect it to be one of your overcurrent protection devices
in the down position.
- [Eddie] Yeah.
- [Gary] And you can get somebody to reset it,
at least try the starting process
to re-energize the circuits before you arrive.
- [Eddie] Yeah.
- [Gary] Because these panels are installed by
you all over the country, aren't they?
- [Eddie] Yeah, all over the UK, yeah.
- [Gary] Yeah. So a bit tricky if you get one in Scotland
for a breaker that's just tripped when you can actually
solve that problem over the phone, yeah?
- [Eddie] Oh, yeah, definitely.
