2-core flex is my solution for the ELV side of door bell transformers inside a consumer unit, round or flat, 0.5 or 0.75 mm2. No issue then with Band I and Band II circuits being in the same enclosure as the insulation is all rated to the highest voltage present.
NIck, you do a terrific job on applying the bonding. I'm sure the owners will appreciate having the holes filled and the decorators should be well chuffed that the patching is already half done. Anyone who complains that you have not "leveled" off the bonding is a dope. For the job to be done right, it has to be applied in two steps.
I'm a grumpy person who hates change, but I've just relented and got a Megger X1, and am loving the instant logging of data to CertSuite on my phone, even when there's no internet. My wife has noticed that I'm not writing certificates in the evenings. And I don't lose slips of paper in the van any more! (I wouldn't use an X1 for fault finding, the IR tests are toe curlingly slow!)
Nice tips on there Nick. I am an old school sparkie and the letter tips was a very good (and new) tip to use. I also send the links to your vids to my college students and apprentices to use. Excellent and impeccable work as always, lovely to see a (proper) trade 😂 taking pride in their work.😊

Absolutely brilliant work with the labelling of the cables/legend in fuse board
I used a double din rail box thing for the ring transformer that Screwfix sell, complete with the transformer Feed from the lighting circuit and tucked away
Hi Nick, Love the videos but just a quick tip if you use the link lead you can get a good reading on a circuit which is actually faulty due to parallel paths through the bonding. You need to remove the cpc from the earth bar to test the final circuit.
I had the (ubiquiti) doorbell transformer taken out and put into a 2u plastic enclosure, on flex and that on a 13a plug into a socket in the electric cupboard. Easy to reboot, and freed up 2u for circuits.
We used to add a ‘’bonding coat’’ and a ‘’top coat’’ after a rewire as well so you’re not alone Nick, and this was back in cira 1980 ….its called going the extra mile doing a good job speaks volumes , and this was when i was an apprentice
As a note, could you not use POE on the ring door bell, I have a ReoLink and in the US it’s POE so no dedicated/shared fuse or power supply required! Do you also run network cable to attic and network locations? Nice neat panel!
Nice job. The only thing I can offer to improve is to use double pole rcbos instead of the single pole ones Also, the issue with fitting doorbells transformer inside consumer unit is it goes against c.u. manufacturers' instructions to fit 'non-standard' or 'non-compliant' or however they may word it inside their c.u
Great content Nick as always + great idea on changing the colour of the tester , any time you want to give up the tester, I would be interested saving up for one ⚡️👊
Brilliant idea, don’t get why they don’t make emergency lights a standard requirement at board! Could bell not have went into a small box at side which would have left spares available in board? Great video and work.
I got to say every sparky should be doing a bit of bonding like that, but these days many tradesmen won't even dabble in other trades to help clean up their mess.
With you 100% on colour of tester. It put me off buying it. When i finally got one its the best tester ive used. Change the colour, use metrel leads and its the best tester 😊
Question; When using the small magnetic r1 r2 lead to link out in the CU....how is that confirming the continuity of the cpc? I ask because my apprentice had a good reading doing this....and the earth path was via some pipework at the boiler....and I had deliberately split the cpc at a socket on the ring to prove to my apprentice that linking out at the CU this way does not prove continuity of the circuit cpc, and should a plumber arrive and insert some plastic pipe in the future... you now do not have a continuous cpc reading on the ring. So my question is... are are you 100% certain you have a continuous cpc on that circuit using this gadget, as I managed to prove otherwise??? Best to do end to ends prior to insertion into the CU to guarantee cpc continuity.....me thinks...
If you ever worked at my house and I saw the bonding, I would appreciate and understand what and why you've done it. There are people out there who are happy to do the minimum and then there are people like you who give a shit, please don't change, you are appreciated by those that care.
Nice job, but cat 5 isnt rated to 230v, therefore induced voltage is still possible. Have you considered using 2 core 0.75mm flex? it ticks all the boxes & easy enough to use. & i always fill my chases unless it's a re-skim. Customer then only have to final fill & sand to their requirements. Not all customers have decorators & plasterers on tap.
why should it be rated 230V .. it's only used for 12V.. I do'nt think bus cabels for KNX/EIB are rated for 230V .. maybe this is the reason why UK is so behind on smarthome/domotix .. All video's on youtube are almost the same small fuseboard and still oldschool switches on 230V.. Here on modern houses/renovation we put every light with seperate cable/flex to the board / same for switches via bus cable or even cat5-6 cable .. al to the same large board . With combined voltages 230 - 24V DC etc .. My fuseboard is about 144 modules big ..
@@kittsdiy our regs state when extra low voltage cables sit along our mains voltage cables both must have insulation rated to the higher votage cable, seperated by 50mm or a barrier. Or you may get induced voltage on the ELV cable & raise it way above the 12/24v it was originally rated at.
06:55 what funny rule that is in UK .. we do it all the time with teleruptor/plc/domitcs . 230V & 24V combined in same board ( in Belgium ).. and not doulbe insulated cables .. al industrial board in factorys are all like this .. why would DIN RAIL supply/transformer even exist ..
For a while I was wondering which earth bonding Nick had carried out that people in the comments were referring to. Finally realised that it is a product for filling holes in the wall. Does anyone know why it's called "bonding". It doesn't look like dot-and-dab board adhesive. Does it "bond" to a wall to prepare it for plaster skim?
With the ELV inside the CU, this is another classic area of product design failure. The doorbell supply should have a seperate cover over the ELV terminals, locking, with a strain relief (this is all trivial to put together, we're talking a cable tie loop and a snap over shield), and the cable should just be slid in a piece of 600V rated PVC tube (.. basically the same as sleeving) while inside the CU. Alas, the manufacturers aren't inclined to design products to support the regs, and the regs aren't inclined to support reality.
I know you mentioned budget, but the difference between an 18 way and 24 way board plus blanking modules is barely even £20 if you installed the same amount of circuits. Seems a bit short sighted by the customer.
BG transformers from TLC are compatible with ring doorbells - but is it compliant to install a BG transformer in a Fusebox or other branded board.... as it's not switchgear..... hummm?? the debate starts!!
Bit of a misconception in the regs with this mate, the fuse board needs to be made of a non-combustible material but it isn’t there to contain fire, so it can be mounted on Wood and you don’t have to use fire sealant. Hope this helps
Parallel paths are irrelevant in this case, as you are effectively just creating a join between the live and CPC to test a loop. Would get exactly the same reading with or without other cpcs connected
@@joesouthgate wrong mainly electrical done a video and proved he got a false reading with earth disconnected in circuit and still got a reading via testing at the earth bar
nick, may i ask of you please.... we had new solar panels and consumer fuseboard fitterd through a government scheme last week ( 5 properties) on our block, i have noticed that theres no cert for test on the consumer box or singed next test date is this right? thank you .. jim p.s. my writing or spelling isn't right due to having had a stroke years ago....
There should be certification completed. An electrical installation certificate and MCS paperwork (if relevant). It should be given to the person ordering the work. Not sure if your the property owner/ordering work or the tenant.
@@richardwilliamson3624 thank you for your reply, we own the property and we not the only ones who have had it done. but i think may be the others have got already installed consumer units and they just had panels & storega heaters. we had solar panels storage heaters and this consumer unit, it dose have stickers saying in what each mcb is for and thats is it. on the switches for the solar they have 240volts and dc on them. if i can i shall try to put photos on ... thank you richard. jim.
😂 Needing internet to set up a private doorbell. You can buy WiFi enabled doorbells that don't need an amazon account with no risk of Amazon shutting down your service/account or not supporting it in the future, and making more ewaste along with the fitbits and Samsung watches that won't work with any new phone
Yep that’s a thing. I had Amazon product to connect the land line to the Echo’s turning them in to speaker phone answerable by the echo, great if you have your hands full carrying something. They turned it off. I paid for the device it dosnt need any cloud support, but they didn’t want to support it and boom, you will own nothing (even if you paid for it) and be happy. Bloody WEF. They can F R O.
Why waste two ways in a consumer unit with a transformer, crazy. All that room at the side of the board just use a stand alone Tx or mount it in a 4x4box
A low voltage cat cable should not be installed or inside a consumer unit . If I did an EICR on that place I would fail it . That in my book is shoddy workmanship. Your neck I'm the noose if it goes tits up. So don't bang on about regs when you ignored them you don't mix low and high voltage cable.
There will always be haters and people that will find fault no matter what. But top job as always. I really like that r1+r2 link less where did you get that @Nick_Bundy_Electrical ?
for the Kewtech. . . would they let you spray paint that one? Yes, the colour of their tester is TERRIBLE! Yes they should bring out a limited edition version so electricians don't walk around building sites with something that looks like it was made by PlaySkool. Kewtech: restricting their income by making the colours of they awesome tester sht.
I said the same to the rep a few years ago that the testers look like toys. They’d probably look better in black - like the new Megger but but the Kew tech would work 😂
