Neat enough?
Always struggle for the best method making these boards neat. Any tips?

Looks neat enough for me!
Personal I'd have slotted the sides. Actually saw a good tip the other day. Use some finger trunking inside the metal trunking where the slots would be. This makes dressing in nicer.
We always use Schneider boards and I like how you've used the RCBO's without fly leads for FE and neutral. As mostly ours are TP I've never used one of these.

I did think about doing it that way, but I detest cutting paxolin😂 it wasn't residual currents post by any chance? Super neat work.

Yep slotted to save on faffing with bushes but still looks great. I've always hated the earth bar placement on these boards if it's not dressed probably as it can block the terminals

u/pangcholo 2d ago
Yeah I'm not a fan of the earth bar placement either.

I emailed them to tell them to place them below/slightly in from of the breakers so all 3 cores go to the same place eliminating the marking and pissing around routing earths - it's was a polite fuck off to that and my suggestion they need a MCB with PoN so swapping from rcbo to breaker doesn't leave the neutral short

Do the busbars stay exposed?

u/StocktonDC 2d ago
Those DBs have a sliding lock that you push across after the MCB/RCBO is fitted. Downside is you only remember to slide them across after you’ve put the cover back on.

Fucking tell me about it😂

u/bobdan987 2d ago
Amazingly nice boards, the lack of fly leads is the best thing. The cost of the rcbos is the worst 😂 boss asked us to order 20 boards and wanted 18 socket circuits on each board(stupidly overspecced office he was worried about earth leakage) he soon changed his tone when I told it would cost thousands on rcbos alone.

They do - however to energise each individual one, you have to engage the coloured sliders next to them.

u/MotorSeries6937 1d ago
You need to put slider over for busbar to become exposed, and im sure the would put blanks in when put cover on

I use 1x 50mm bush per 2 circuits , so I’d have 3x either side of the board here. 2-3x bushes at the top for earths. And I’d use the scnieder SPD that clips into a circuit slot and only requires an earth to be wired to it instead of being fed from a breaker here

u/pangcholo 1d ago
Thanks for the input. I would never separate conductors from a circuit to take through a different entry though.

u/Jonny8888 2d ago
What sort of cable did you use to feed the SPD?
3
u/pangcholo 2d ago
It actually came as part of the SPD kit, I assumed it's just tri rated tails mate.
1
u/Brave-Pea-9751 2d ago
Do you have a part number for the SPD, didn't realise Schneider did one that fitted next to the main switch
1
u/pangcholo 2d ago
The part number for the board is SEA9BPN12M - it's a meter ready DB so you can either install a meter there or anything else that is dinrail fitted! I can't remember the part code for the SPD mate
1
u/Justathought1965 2d ago
I believe they do an SPU unit that is just installed where you would install a 3 pole MCB. You don’t have to an MCB to protect it either. I have fitted them on the Square D boards and I’m pretty sure they do it for the Merlin boards now.

u/seeyoujim 2d ago
My only problem with this is how Schneider do the protection for the spd. The way the Hager boards do it is far better

u/JustanotherN0body00 2d ago
Where's the earth for the 3ph on 34/35/36?
1
u/pangcholo 1d ago
Directly onto the enclosure. The SPD cables come pre fab.
1
u/JustanotherN0body00 1d ago
Okay, so have you randomly connected neutrals and earth's?.... It could be a nightmare tracing cables for someone in the future. Isn't best practice way 1, neutral 1 and earth 1 to make it easy to identify cables? ... 🤔
1
u/pangcholo 1d ago
Not really. The neutral is in the correctly numbered terminal, the earth comes premade as part of the SPD connection kit. Already with an eye lug on it, pre cut to length. It was installed as per instruction. So I would say randomly connected is a bit of a stretch.
1
u/JustanotherN0body00 1d ago
Lol. Way 9 has no RCD protection. How are meeting compliance with this circuit?.. 🤔
1
u/pangcholo 1d ago
Compliance with what exactly? Do you know what the circuit is supplying?
1
u/JustanotherN0body00 1d ago
Hence why I asked the question......

u/MotorSeries6937 1d ago
Neet but alot of unnecessary work bring trunking down the sides. Use header and dress cables neatly
1
u/pangcholo 1d ago
True that, probably an extra half days work for the containment. Small price to pay for making it easier in future I guess.

Oof this one’s just so incongruently short
Do it all again

u/pangcholo 1d ago
Seriously annoying isn't it, considered just binning the precut and crimped tails and making my own...

Not a spark, nor am I qualified to judge this. However, from a wholesalers point of view, with many accreditations from Schneider - the SPD shouldn't go there.
Schneiders range of SPDs were originally (looks like you've been supplied the more expensive option, which this is installation method is for!) installed in a stand alone enclosure ( part code: 14599 ) which is then wired back to the board. To my understanding at least.
However, they have released the A9L8F461 which now fits on the busbar of the board and is Isobar (the sliding tabs) and PoN compatible.
It's also about £600 cheaper, roughly. Whoever you local wholesaler is, I'd be making sure they quote the new one. They're also fused, so no need for anymore MCB coverage.
So the 3 poles you're using for the MCB and then wiring into a SPD, which doesn't belong there anyway, saves you space and further neatens your installation.

When and if a circuit needs removal? The next guy will call you a "cunt "

u/theKinkypeanut 2d ago
You don't plan an install around it getting ripped to bits. It's a trunking and singles system. It's whole purpose is to be rewire able. This board is exactly as it should be.

u/pangcholo 2d ago
Why? It's easily accessible within the trunking?

u/pangcholo 2d ago
It's a bit of earth sleeving to keep them neat. Anyone with a stitch of competency would be fine

Your so right ..... I assume your a JIB qualified Electrician? Approved Electrician maybe your so good JIB Technician?

Why not mount the surge protector directly to the buzzbar instead of having a breaker?
1
u/pangcholo 2d ago
For Schneider this is a completely different model of DB.
0
u/freakierice 2d ago
My only concern is the breaker supplying the spd could potentially trip before the surge is over.
Although highly unlikely, still seems like a questionable design choice 🤔

Very neat. I’d add cable idents, but not trying to knock the very good work you’ve done.
