- Welcome back to another exciting episode where Chris and James are upgrading a consumer unit installing new smoke detectors and upgrading the 16mm tails buried in the cavity to a new 25mm SWA cable.
Pablo did a great job on the mains and installing a lewden switch fuse.

It is good to hear your thought process when installing the SWA cable. From the finished installation I did not know it caused you so much hassle. Very pleased with the end result. I cringed when I saw the heat damage to the two circuit breakers 😲😲😲. Thanks to you both for a first class installation. Look forward to having the EV charger fitted.
Pablo's a busy lad having to do double shift 😂
I was thinking the same thing 😂
Pablo does all my disconnects aswell, he’s a good lad !
That armoured looks a bit sore on the outside of the property tbf
Agreed it looks shite
Good old Pablo coming and helping you out again, he's a really useful chap to know! 😄
I was a house basher for years, now I do nothing but commercial/industrial and now something like a 25mm2 which used to be the biggest thing I used to work with, are now only baby cables for small sub boards.
Nice work.... The spark who did the feed for my garage skated around using SWA (for whatever reasons) which I specified and he ended up using a split concentric cable which he certified. I wish we could also be clear on the use of CY and SY cables and how it applies or does not with the 18th Edition (not for fixed installations !) and someone needs to make a video about it, even if it's a 'we are not clear about it' one.
I think as long as the mechanical protection of SWA isn't explicitly required, you could always use NYY-J. It's not exactly flexible either but without the armour it should still be a bit easier.
I’ve grow to really like the no nonsense practical videos
Pop a wiska box externally for the ev charger and feed it in twin. Then run armoured out of the wiska box to the ev charger
That armoured cable is ugly as sin can't believe the homeowner agreed to that.
you just saved me from typing the exact same thing.
Certainly not the prettiest, but what would you suggest to improve it that complies with the relevant Regs? These set ups are a nightmare for this sort of job! No thought put in for future works!
@@jamesyoung8945 junction box at floor level then come up through the box with singles
James is very tall! saves on step ladders
Well done Chris on that drilling from the outside to in, talk about precision, you couldn't have wished for a better through hole, damn
That 25mm armoured cable is tuff to wrestle with 😯
Just a question - could the armoured have come through the wall low down then be fed up inside the heating pipe box? Would be neater, a bit more making good but better than the run up the outside wall?
It’s an extremely ridged cable and to get the 90 turn at the bottom of the pipe box then again at the top combined with glanding swa into the board with the length of tails required to come through the board wouldn’t have been a very pleasant day 🤦🏼♂️
You only look at the outside of your home infrequently, internally all the time
You're supposed to to bring the inner insulation past the gland body and into the item it's getting glanded into. Most industrial jobs would make you rip it out and do it again if you done it like you have done.
The way the conductors pass through the entire switchgear causes that in the event of a lightning current is induced in the indoor installation. Surge arresters should be fitted at the main tails entrance of switchboard.
On the next video Chris, give James the camera for the day to record his work. Or not a day, just for a short while lol. I do like James 👍
I have mentioned this before, so many contactum 16th edition consumer units I've removed,most mcbs show heat damage
It's far easier to make the gland off on the cable first before you put it into the consumer unit or any other enclosure for that matter.
Then it's just a matter of pushing the gland body through and putting the locknut on and it's better to help 'dress' it in.
That way you can also ensure you've got all the armour in the gland visually.
Good job otherwise but have to agree with others over the aesthetics of cable externally.
Keep up the good work.
Pablo must be on bonus 😏
How many more boards and let's face it we have all come across the problem,before they design a a sure safe way of connecting the cables in to the breakers and the busbar ,bring back the old wylex board system .
@Dark Stranger must admit come across there old boards and was impressed,must have a look at there new range 👍
There just seems to be a massive disconnect in house design between the meter boxes and where new boards are installed, also seems weird running tails within cavities along an odd route you can not pull though. I would think this is just waiting for some good regulation to make it easier for people in the future.
Personally, ive been looking at some new builds and the fuse boxes in the living room at mid level and the meter box other side of the house, what happened to the normal idea of having the fuse board in the hallway.
Ah the boy look confused with the rackateirs 😂👍
8:04 you can take that one home James and put it in your bedroom can’t you. 😂😂 thats what I do 😂😂
Dont look flash on the outside wall and under the front step a big no no here in Australia even if it is armoured.
@@zlmdragon. Can still get damaged even though its armoured .The Sun in Australia with its harsh U/V rays would soon destroy its insulation it is also required to be protected from mechanical damage with conduit, cable capping etc. Plus the big one is that it looks like crap.
Is there not an issue with the proximity of the SWA to other services/hot heating pipes ?
And would this affect the current carrying capacity of the cable ?
Nothing worse than terminating 25mm SWA in a submain. No room and the cores are rock solid. Nicely done though.
17:28 Amazing to see how small the DNO can make the supply cable by combining the neutral, PE and physical protection all into one in a layer around the live conductor in a coaxial configuration (especially when compared to the armoured cable)…
Yeah concentric
correct me if i’m wrong but isn’t the supply main 16mm anyway always thought it was
@@Tyler-ph8bh Not really, combined neutral Earth (CNE) cable is only 12.3mm diameter in new builds for 25mm, older cable is separate neutral earth (SNE) but still only 15mm diameter for the same 25mm.
I would have been tempted to use 25mm split concentric myself for the submain
The DNO don't follow the same rules as we use when it comes to maximum demand. I once done a very small hotel rewire and we worked out that the supply tails would have to be 70mm on a 3PH supply and they only used 35. The lad who worked for them told us they follow a completely different set of rules
Pablo Fantastico 👌
Why is it all sparks in UK find is so difficult to buy 3 core swa with proper core colours??
You can blame the EU for that one.
I managed to get some 2.5mm 3core swa in the proper colours last week.
it's illegal here in Ireland to sleeve 3phase colours to represent earth and neutral
Sorry Brown blue green yellow from batt cables
@@CiaranTrivium do you have the electric police come around and arrest you 😂
What size fuse did you use in the switch fuse box is it the same as the main or dose it need to be lower rated
Chris, you’ve definitely got covid with all that sneezing 🤣
Wtf. Last time I watched one of his shows he was praising up crap tools and criticizing expensive tools. Now he's rocking shiny new Milwaukee. Good on him👍
Don’t know why the armoured couldn’t come through at low level and up the boxing where the pipes are, would have been much neater
Couldn't you have split the tails at the meter and fed the EVC from there to avoid replacing the feed to the board?
I assume not as the tails were in the fabric of the building with no rcd protection. Also the new consumer unit for the EV charger would have to be outside the meter cupboard due to space limitations.
Not in this case, that cabinet was so tight for space. Looked about half the width of the standard type cabinet.
You would need a main isolator switch and then the tail splitters and a consumer unit, just wouldn't have fitted.
I'm sure those existing 16mmsq tails were over 3m and therefore deemed not to be protected by the 100A cutout fuse - a non-compliance Chris had to get rid of and hence even when upgraded to 25mmsq SWA he had to fit a downstream switch fuse.
I have thought about different ways this could have been done - but there was always a reason for non-compliance. Chris was bang on with this one. Blame the original designer of the house for him having to run that SWA!
Simon it’s nice to have a comment from another top sparks with common sense and not trying to bash me on ever video cheers dude.
@@Cjrelectrical I vote you block the sod.
@@simonparkinson1053 Agree 💯% mate! Chris has done exactly what I would have done here, can’t see any other viable options. 25mm SWA into a switched fuse in meter cupboard is literally one of my least favourite things as you said Chris you never enjoy it! The last two I did still had the trenches dug underneath them so kept falling in doing it 🤦🏻♂️🤣 just for added fun!
That’s some serious cable.
I did a fuse box board recently that was fed with a 25mm SWA, and there was no way I could get a 25mm conductor in the earth bar. I ended up putting a lug on it and bolting it to the board.
You can use a 25 to 16 or 25 to 10 reducing crimp.
@@lewis94uk that's interesting, I asked in the suppliers about one of them, never heard of them, must try another supplier, thanks, I didn't notice one in that board.

Done a 35mm in domestic before, nightmare to get it in the switch fuse!
For some reason I expected this house to be newer than it must be, but given the black/red coloured wiring, it’s gotta be at least early 00’s 😳
in all fairness you could of used 2 core 16mm and ran a separate earth in just to make it easier.
I recommend the OX Tools OX-P044440 Pro Heavy Duty Sealant Gun, Multi-Colour, 400 ml, £17.95 on Amazon.
Not a straightforward job at all but you've do a crackin job of the board spot on mate 👍
What is the device on the right inside the new main switch enclosure? Fuse?
Can I ask. Clearly the original tails were longer than 3 Mtrs. If they had been less than 3 mtrs would you have been able to keep them even though they were run through the cavity ? What are your thoughts. Cheers.
Great video mate keep it up always love the content, can u do a video on essentials to have in the van please 👍.
Just put a James in the back sorted
@@Cjrelectrical 🤣🤣
In certain industries eg plastic moulding by electric heating. Someone is tasked with just regularly tightening screws. Yet in houses a screw after 20 years is as if nobody ever tightened
Could you have kept the original earth, I'm assuming it was 10mm if the meter tails were 16mm. As you also glanded the armoured would that equate to 16mm? Then maybe you could have used 2core armoured?
Why are the UK distribution boards either so high up or stuck in a cupboard low down?
I think here in South Africa it can't be low to keep out of reach of children but can't be higher than 2.3m either.
Also this single phase household thing boggles the mind. I've got three phase 80A per phase, so can run a LOT:
three hot water cylinders, stove/oven, washing machine, tumble drier and dishwasher, swimming pool and borehole pumps and there is still room for heaters / air conditioners etc.
Neutral ends up carrying very little load.
Chris lovely installation & brilliant effort by both of you,👍🏼 even tho the armoured SWA cable looks hideous by default.😬 The arcing heat damage was ⚡️shocking⚡️ (Pun intended)😱. You can't be too careful with electrics. The board looks a treat.😉 Looking forward to the EV charging video. Poor Pablo.😁
Why do you need to replace the tails, can't you just fuse them appropriately with that fuse holder, 60A?
My guess is property needs more than 60a?
@@electricalstuff259 it will when the ev charger is installed at a later date
Main fuse should be 80 amp anyway
35mm split concentric is the biggest ive used in a domestic property 😉
Best is to hire Artisan Drilling for best results.
Yeah I had to ring him to ask for the pythagoras theorem formula
Do you add the Ei3000MRF radio modules to the Aico smokes for making them radio link or use a Ei168RC radio base instead (assuming no interlink cable is there)
Interesting you decided to sleve the black as an earth given a black was a neutral in the old colours, sleving the gray seems more logical to me less confusion when terminating both ends (sleved in new colours off course).
I can tell you are not a sparky then Mark.
@@Cjrelectrical De neutralising the neutral brigade are we,what has BS 7671 to say about it???. Funny thing is I did my part1, 2, and insp testing, skills test way back in 97 as part of my electrical apprenticeship as well as a ONC, HNC and NVQ's related to my industry. I never used my domestic qualifications much and have never been registered as a domestic installer as I worked in industry as a Maintenance Engineer. Doing my domestic qualifications was just an introduction to industry, I worked in a number of factory enviroments before graduating to the generation sector wind and more recently power station work. So as you can appreciate my domestic experiance is very limited and what I do on a day to day basis is very diffrent to what you do. My comment was not ment to offend, I like watching these clips just to keep my eye on the domestic sector as single phase working especially in your enviroment is very rare for me and watching these clips interest me. Also they help me keep my eye in as a there have been lots of changes since I did my domestic qualifications many moons ago.
Chris has sleeved the armoured correctly in accordance with guidance on harmonised colours. No issues there.
The fact he cant spell "sleeving" says it all. Obviously not a sparky if he thinks black is neutral on a 3 core and earth cable. Deluded
What are them red washers ?
Why do you have those cartridge blanks... because of heat dissipation?
Just a quick question, are you allowed to tamper with grid company's equipment?
No, he isn't, that's why the mythical Pablo keeps coming to help. I think Pablo also used to have a colleague named Deano for a while.
@@Ragnar8504 you are right, I've missed that mystical Pablo part because when he has got the fuse , there was no hand or shadow front of the door . I also was wondering how nice of mythical Pablo , he has removed the fuse holder and wasn't enough . He also taken apart that fuse holder took the fuse out and gave it to electrician. That doesn't sound right to me :)
And could that close proximity affect the current carrying capacity of the cable ?
You should try a 400mm 4 core or even worse a 300mm 4 core solid aluminium
Yeah seen them on the hospital sites I used to work on biggest I pulled in was a 5core 250mm that was fun 🤩
SWA into the board bit of a bugger.
Love the vids, great content, always enjoy watching.
Why don't any CZcams sparks drill out a brick or 2 and fish new tails up the cavity? Just seems a shame to see armoured and trucking on a house. So what's the reason you don't take bricks out to fish??
New installs we cannot install inside the cavity
@@Cjrelectrical if you don't ask you don't know. Cheers for you reply.
I've just thought, I think I know who Pablo is, I will confirm with you at Elex
Wow, really impressive drilling, bang on!!
I had pretty much the exact same install today, why don't Fusebox make something where you can have the tails on the left side of the board? It made life hard for me today!
Gaz from efixx said we can't put EV charger equipment inside meter boxes.
Good video Chris, James & Pablo!!
I am glad you are a doctor and not a detective! I have used Pablo for years👍
@@bartman58 Hahaha, yes, I'd make a rubbish detective!
Had your work cut out with this job…. Bet you was glad to go home
People who drive Electric Vehicles have a lot to answer for ....
Chris what are the red penny washers you used to fix your consumer unit ?
Are you allowed to fit the fused switch inside the dno box?
Saw a vid on effix and it was definitely a no no
I've got a 60A fused switch in my house which is inside within 3m of the cut out and then armoured to consumer unit in garage
99% of new build have a switch fused fitted in the service box
@@Cjrelectrical it's a sensible idea, they should fit them when they fit smart meters but when does sensible make shareholders money.
Most of us have done it, and we all know we are not meant to, they fit isolators in their because it's their equipment, where I live, the back board always had, in bold writing MANWEB equipment only, that's before it became Scottish power.
Customers have to pay for meter boxes and are responsible for maintenance so no longer the property of the dno
What is that next to the main switch isolator?
Did a similar job not that long ago with 25mm swa the grief I got from know it all’s 🙄
You don’t need to fuse it/you don’t need to use armoured etc 🤨
Nice one Chris a good safe job and 25mm don’t like being dressed does it?😂
Keep pablo in biscuits 😉😊
Hello, would concentric not be an easier option for jobs like this,not a criticism just a question ☺
To be honest, that's what I would have gone for, it's easier than wrestling with an armoured, and if the lid was off that boxing could have gone up in the corner in the ceiling then in the top of the board
With that big arsed box you put in the meter box there is no room for a smets2 meter now. If the customer wanted a 2 rate smart meter to take advantage of the cheaper night rate, he/she couldn’t 😳
Well it's a small meter box anyway so can blame him tbh
100A main fuse with 16 mm tails?
Pablo needs to show himself in a video🤗 And having OCD sucks.
Pablo is always there, you must have missed him
I have a very strong feeling it's James he's only saying it's someone from the dno so people don't moan at him
Good stuff but is it just me thst would have put the customer off till I had armoured and then do it in one go on same day🤷♀️.
To much work for one day with did other bits not on film to
How comes there is a Isolator and a Switch fuse installed? Thanks in advance ☺
It's to protect the 25mm swa since it's over 3m from the origin.
Also, side note, how the hell do you get 'PABLO' from the DNO out so quick for every job>? Takes weeks if not months for us, also, what did you use to strip back the outer of the SWA to reveal the strands while it was in place??
I have a very strong feeling it's James he's only saying it's someone from the dno so people don't moan at him
How come you don;t plan to just take the EV cable straight out of the meter box and along the wall, using one of those small IP rated consumer units in the meterbox or just outside it?
Is this a joke question?
Fair point. That way could’ve kept the 16mm tails to the board in the house. This seemed like solving a problem that didn’t need to exist in a house where room and access was a challenge
Ever heard of earthing nuts!?
Excuse the ignorance but why do you need a Pablo ?
FULL DISCLOSURE: I am not an electrician and my area of expertise couldn’t be further from the trades. I do grasp the context of “Pablo” but please explain why “he” has to attend. I apologise in advance for my complete lack of knowledge around sparkyism.
@Rob Amner loose lips sink ships! It’s the sparky version of automotive CZcamsr’s going to “Mexico” for a race. 😬
❤❤❤❤❤❤❤❤❤❤
Struggling with 10mm armoured? You should try getting some 185mm into a top of a panel 😳 NOT fun!
That's 25, not 10. Still a lot smaller than 185 though.
Am I the only one who hates it when they stick consumer units up near the ceiling ?
id of rather downgraded from a 100A main fuse to a 60A than have that SWA like that.
Happy to change the board with tails over 3m then with no protection and buried in the fabric of the building?
@@Cjrelectrical id of moved the fuse board if it was my house
What’s the reason for not having customer ring their provider up and have an isolator fitted instead of this “pablo” cut the seals?
Use a Piranha on the isolator box.
they're more expensive but I use them every time rather than faffing around with banjos and having to drill your enclosure
I like the channel Chris , but that SWA is just a shoelace
How comes janes never works with andy?
So tell us why not then ?
not gonna lie that swa looks awful clipped outside the house like that
Man your panels look so different from panels in the USA or I guess you call them fuse boards
Also our highest breaker cannot be more that 6'7" so I've never seen one up against the ceiling like that. Is that normal there?
@@lawrencehaslup6889 it's normal in old houses any new domestic property's would not be allowed to place them at that height
@@liamfenwick6320 gotcha, makes sense
How come you have a blank between two rcbos ? I've never seen that before is it for future proofing ?
I think the idea is for heat dissipation as the higher loaded RCBOs will get warm
@@havoctrousers RCBOs do get a little warm even with no load - there are electronics in them.
Even at full load, things will stay within spec.
I do something similar, it gives the opportunity to install an extra circuit in a logical place in the board at a later date, whether you lay out high to low rating or in "geographical" groupings
Good job Chris
Nice job 😎
Nastier sneezes
What wage are you on a day rate
East or west cjr is the best.Great.
Why could the EV not be supplied via a Switch fuse in the meter box ? No need to change the 16mm tails if you did that.
Exactly my thoughts
That would be classed as a consumer unit.
Just like the one you have already installed? Check the definition of a CU ? DP switch, with one or more circuits, you have a DP switch and one circuit ? (the house)
Pablo, will not be happy, you have taken up space in his box with a CU ...😳..... If I where you customer I would be will p off at that SWA around my front door, will look great at Christmas with some leds wrapped around it !👍👍
No it’s a switch fuse feeding the house not a dedicated circuit. Definition of a consumer unit is feeding 1 or more sub circuits connected to the supply of an incoming mains.
@@Cjrelectrical Funny guy ! not a dedicated circuit ? it only supplies the house .
Why keep saying "look" ??? We are looking!
Looks awful
love a consumer unit swap, me.
Hi need jop
Did it not occur to buy the proper cable?
Using 3phase on single phase jobs and plastering with tape is just crap..
Also banjo are SO for guys over 60, get a proper earth nut!
Wholesaler had in stock and it’s heat shrink in the consumer unit
@@Cjrelectrical Just look s shoddy, I stopped using that kinda stuff years ago, 5C over a 4c+over run and if single phase always the right cable, before you know it your are in installing un-branded "Fuseboxes"!!!!
