I’m not a spark but as a complete and utter novice who knows nothing about electricity and also one who is quite happy to leave these sorts of things to the pros even I could understand what was going on here !!! So well done Matt for making such an easy to understand video !!!
Awesome man! Thanks vm! Bought a new cooker and installed it myself after watching your video. Saved me some cash for paying an electrician. Thank you 🙏
Here in Germany wie use flex cables to connect the cooker to the wall terminals. That is much easier to connect and move the cooker after connecting the cable. The VDE standard also recommends the use of flexible cables for applications like this. Eg H05VV-F 5G2,5 H05VV-F 3G4 or 05VV5-F 3G6
You shouldn’t use the cpc to strip cable because copper is soft and it actually stretches it, slightly making it thinner, increasing the Zs an the protection of the appliance. But most people do would I would never recommend it to anyone.
@@jamanemaraashollington8760 You're not stretching the whole cable. You're stretching 2 ends by a millimeter at most which will have a negligible impact on the impedance. The benefits outweigh the risks.
Using CPC works upon 1.5 or 2.5 but you will struggle on a 6mm and don't even bother on 10mm. I use a Stanley carefully to get through but I then cut away from my body/hand so far so good
Very satisfying Matt 👌 would definitely still isolate it's dedicated circuit as well as DP & test, as you're in a non-controlled enviroment.. Just in case say a family member flicks the switch back on, great video
never rely on any switch . If the old cooker was installed with a bit 2.5 old twin and earth how do you know the switch is ok [i have seen so many bodged installations in my time ]always turn off at the mains
Nothing wrong with the isolation carried out. You proved the circuit was isolated by the switch, that your tester was working, and the switch was within your sight at all times. Whilst not strictly by the book, it was safe. In fact, if you didn't have any lock offs with you, that was safer than isolating at the CU, because you could see the switch.
What a video. I stumbled upon this after watching 2 you tube pro's. However, this video is the complete package. Well thought out and executed video. thank you so much. I can now move forward after thinking where the hell is my cable for my new bosch serie 6 double electric oven lol (they could have provided a 6mm 3 core cable). Thanks
good video, and I know its commonly done and its a 6mm circuit, but as a training video, is a 6mm t&e the correct cable selection, manufactures instructions should be followed when installing new equipment, high powered ovens normally always recommend using a 80- or 90- degree temp, oil and grease resistant cable (min 4mm). use a 3183tq cable as the t&e used does not have these properties, or refer to chapter 52. 522.2 talks about heat sources, would 522.5 (AF) include oils and grease I'm not sure. not necessary for this but 521.9 gives info on flexible cables for connecting equipment.
Thanks Matt . Good video . Happy to see you doing what I would do . Did you mention the R1+R2 test too ( which is in addition to the Zs ) to be recorded on the 18th Edition certificate ? Adrian
Matt. Can’t thank you and the other lads enough mate. Lovely to see you guys helping us inexperience sparks how to commit and complete. Very much appreciated. Question on testing; is there any difference in testing a circuit which is wired on 3036 fuse board? And where can I possibly locate those information on testing that kind of fuse board please? Links
Thanks for the feedback and watching. No different tests if the circuit is protected by a BS3036 fuse only the max circuit impedance (Zs) will be different. 😁👍
I’d prefer not to use flat twin and earth to cookers. Usually try and use ho7. More flexible and designed for that use. Could possibly get away with 4mm with it too having a higher temperature rating
HO7RN-7 Flexible cable is nearly recommended by all appliance Manufacturers for the final connection, in the manufacturer's installation guides. I was always taught that "the manufacturer instructions are always paramount". Another let down by the Electrical Wholesaler's, not to keep on the shelf what we Sparky need! CEF Electrical and Avonvale Electrics have been stocking H07RN-F cable for years . Another good video.
I also agree. Crimped and terminated, much easier to pull in and out. However I wish manufacturers would allow or a larger diameter round cable (Ho7 into their cooker connection units) at the rear of their appliances. Fiddly and fragile is an understatement.
Would never rely on a DP switch as the isolation point, as you said though, you've already discussed in previous videos the correct safe isolation procedure of locking off and applying notices at the MCB.
Hi. Appliance repair engineers always use the local DP switch for isolation to items such as showers, IM heaters, boilers and cookers. We would expect all our learners to isolate at the consumer unit👍. Thanks for commenting and watching. Gaz
It could be argued that isolating from a local DP switch is actually safer as both the line and neutral conductors are disconnected whereas isolating from the circuit breaker would only disconnect the line conductor.
True if there's a shared neutral but a wouldn't think their would be in a cooker circuit. Also some idiot could just come in and switch the DP switch on if you went out the room for a minute because its not locked off.
@@MrKwelsh If you have to leave the room for any reason, you should re-instate any cover plates and re-confirm that the circuit is still isolated before re-commencing with any work.
I am a bit confused. The Wiring Reg (18th Ed.) says in 521.9 (Selection and Erection of Wiring Systems) Equipment that is intended to be moved in use shall be connected by flexible cables. Like: H07RN-F Rubber Cable - 3 Core 4mm2 would be perfecty enough. (PCP neoprene is also oil and flame retardant.) Max Length: 29.04 meter. The 6mm2 twin +E is not flexible. I am just asking. I have seen other electricians using flexible for cooker and hobs. Thanks
Hi Matt, great video. I'm in the process of doing our kitchen up,and we are having a built in single oven next to a built-in combi microwave oven. Can I supply one 6mm cable and spur off the socket for the 2 ovens. Or do I need to run 2 separate 6mm cable to the consumer unit. Many thanks. Regards Glen.
One 6mm and a dual cooker control unit to spur x2. These ovens usually come with a flex so use them. You have to be careful on correct size breaker though. Instructions will say. Usually 20 amp with allowance for diversity. 10 A plus 30% of the remainder of the total connected load, plus 5 A if the control unit includes a socket outlet
I will NEVER use a knife to strip wire, you risk damaging the conductors (as seen in the video, but often worse). I start the end and use long pliers to peel the grey back whilst gripping all three conductors. This is a skill to be learned over time, so you get quicker.
You will struggle to find 6mm2 flex. Have you seen the size of 6mm flex. Try to terminate that it in the tiny connectors that ovens have. Flex also needs a ferrule, with one of them on you have no chance of getting it in the connector. Ovens are not moved around. Twin and earth if fine. Knife work a bit scary though. 0.66 ohms on a 6mm2 circuit seems quite high. The r1+r2 would put that at 63m of cable, So i presume you had a high Ze, or its a long run. Love the videos. keep up the excellent work.
@@borobert7649 Yes, that Zs does seem a little high to me too... Could be high Ze, loose connection within the circuit or ageing accessories, some further investigation definitely required.
are all the cookers, or what we call Ranges, hardwired? In the US we use 4 or 6 Ft. plug ended cords that are rated to 50 Amps. that way, if the appliance needs to be removed, its just unplugged and then moved. the only built in appliances that are hard wired here are cook tops and built-in ovens.
Lovely job. I do like how you give the CPC a loop at the cooker end always been taught to leave the CPC the longest if possible. A lot of cooker manufacturers recommend heat resistant flex for the cooker connection. At the CCU I have found some manufacturers double up terminals gives you more of better connection was this not the case with his one as the top terminals were loose?
I don't know about other organizations.. But if you issue a certificate of any form through Napit the work done is automatically covered by them for 6 years.
Nicely done Mr Matt. :) I fill in relevant certificates for ANY work carried out, not only is it a good personal record of works completed but it gives the next guy something to refer to in the event of a fault and may also highlight any existing faults. It really doesn't take long to do tests for the form, although 18th requires a lot more info than previous edition. Is there an electrician's version of avacado hand?
Thanks for video, is very helpful. I have a question about cable please. I brought new 10,6 KW cooker, can I still use 6mm cable for, or I need different one??? Thanks once again
Is there a recommended or permitted length of cable to allow for maintenance. Also would like to see the actual connection unit being wired in. Good demo' many thanks.
Hi, some people use heat resistance flex but in the case Matt used standard 6mm2 cable. You can do as you described 👍. Thanks for commenting and watching. Gaz
As a competent diyer I’ll only ever work on electrics with the whole circuit box isolated. Often means a race against time and limits me to daylight hours but it’s better to be safe than sorry. I dont have enough confidence to isolate a circuit in case I’m wrong.
Very formative and good video. I just have one question - when would you use heatproof cable rather than twin and earth? Is that just used on integrated cookers and hobs? I’d welcome your thoughts on this. Thanks.
Most ( old time sparks me included) connect how you have by switching of the DP cooker switch ... yes I Know now they switch of the Mcb now days and yes it is modern practice to do so ..as for seeing T/E ( 2.5) I’ve seen many kitchen fitters. Do this ... and handy men. Will add I allways wire cookers from the mains in 10m as you can never tell what size cooker people buy thease days ...
Mine is also a 32 amp rcbo with a 6mm supply to the cooker connection unit, but my cooker is only 4.2kw which is only pulling about 18 amps should I still use a 6mm from the connection unit to the cooker or would a 2.5mm suffice because it is cable of a 25amp load current?
Nice video Gaz we all do it but is it OK we're the CPC on the cooker terminates it has a pure 90 bend as it goes into the terminal I have been asked by the apprentice but I had no answer for him there is always one haha let's see Iff you can answer that one Please
Am I right in thinking you're question relates to the bending radius of the cpc, if so a sharp 90 deg bend makes no difference on an individual floating conductor.
@@Allegedly2right I think the bending radius is more to do with reducing the risk of a parallel arc when multi-core cable are bend too aggressively... I could be wrong but it's just a thought.
Seriously! Final connection with 6242Y, not 'best practice' with the knife, using any old screwdriver for connections, flat blade driver into a PH screw. Every cooker I have seen in a least the last 10 years has stated H07RNF or similar. On a tangent, serious question....HR butyl rubber ( rarer than a 70s TV personality) and HR flex; is the insulation Heat Resisting or is it just the sheath?
Not many houses or flats in the UK have got 3 phases coming in. I haven't come across one yet and I've been living and working over here for over 20 years
That would be interesting to see a video. Is it called a 3 phase installation and is it common across Germany. Are your appliances made compatable for this system. Regards to you Dirk.
You need to follow the safe isolation steps! The important step is to lock off the device protecting the circuit you are working on ; in other words you need to go to the protective device at the consumers unit and switch it off once you proven the cct its live first! Then prove dead at the point of work ( point of work in your case is the cooker onnection outlet... & go back to the breaker lock that off! USING A PADLOCK AND KEEP HOLD OF THE KEY! Another point to note is that the testing gear need be of an approved type ( a multimeter or voltage indicator sort you are using may not meet the safety standards for safe isolation!) Need be a dedicated proving unit kit ( the probes cable need have no fuses and have visual indicator lights and be one piece & of a gs 38 standardised) A mar tin dale manufactured kit will met the criteria - I'm not affiliated to them! Cooker isolator is there only to switch the cooker on and off by the user and Not for safe isolation purpose.
I'm new to this, in my wall socket its the red and black wires to the sides, and the cpc wire in the middle, however my cooker wire is blue and brown I dont have a clue as I've connect it but cooker not coming on
At 2:24 you say that an 8kw cooker WITH diversity applied is around 26 amps?? With diversity 8000amps /230v =34amps. First 10amps then 10% of remainder 24/30% =7.2amps + 10amps = 17.2amps total with diversity.
So the previous cooker had no cpc connection to the earth terminal, good job Matt turned up when he did.

I came here for Matt, not disappointed 👍👍👍👍👍
Must admit, I had to shut one eye watching you cut the sheathing. Much safer to use the cpc 👍
You shouldn’t use the cpc to strip cable because copper is soft and it actually stretches it, slightly making it thinner, increasing the Zs an the protection of the appliance. But most people do would I would never recommend it to anyone.

Mine is also a 32 amp rcbo with a 6mm supply to the cooker connection unit, but my cooker is only 4.2kw which is only pulling about 18 amps should I still use a 6mm from the connection unit to the cooker or would a 2.5mm suffice because it is cable of a 25amp load current?
Refer to the rule book 2.5mm PVC copper cable can carry a current of up to 24 amps, this rating depends on the method of installation
@matt what do you use to twist the copper so neatly ?
as the oven can be moved to clean under / behind would H07 6mm flex be better?

Not many houses or flats in the UK have got 3 phases coming in. I haven't come across one yet and I've been living and working over here for over 20 years
That would be interesting to see a video. Is it called a 3 phase installation and is it common across Germany. Are your appliances made compatable for this system. Regards to you Dirk.
@@nw5835 Yes, my Stove is connected to 400 V. ua-cam.com/video/Q_f5gtrDQFg/v-deo.html

@@derdeutsche2666 Can be installed in any UK household. 5 wired cable, 2.5 mm, 3x 240 V, 1 x neutral, 1x earth, 25 A fuse, simple!
My cooker has a plug on it but I need to join it to the main twin & earth core cable. How can I do this? Any help massively appreciated!
Is it a mini cooker and that is the rating of it?
You need to follow the safe isolation steps! The important step is to lock off the device protecting the circuit you are working on ; in other words you need to go to the protective device at the consumers unit and switch it off once you proven the cct its live first! Then prove dead at the point of work ( point of work in your case is the cooker onnection outlet... & go back to the breaker lock that off! USING A PADLOCK AND KEEP HOLD OF THE KEY!
Another point to note is that the testing gear need be of an approved type ( a multimeter or voltage indicator sort you are using may not meet the safety standards for safe isolation!) Need be a dedicated proving unit kit ( the probes cable need have no fuses and have visual indicator lights and be one piece & of a gs 38 standardised) A mar tin dale manufactured kit will met the criteria - I'm not affiliated to them!
Cooker isolator is there only to switch the cooker on and off by the user and Not for safe isolation purpose.
So 6mm is good to go on the wire
I live in the US. Things that are weird to me is the sleeving on earth/ground and direct wiring

I'm new to this, in my wall socket its the red and black wires to the sides, and the cpc wire in the middle, however my cooker wire is blue and brown I dont have a clue as I've connect it but cooker not coming on
Black/Blue= Neutral, Red/Brown= Line
Hire a pro electrician.
Not using heat resistant flex cable?
HOR7 👍🏻
@@GSHElectrical I meant the video shows standard 6mm T+E...unless I'm mistaken?! 🤷🏽♂️
A question please
Does length of 6 mm wire from circuit cutter to cooker matter?
Has to be long enough for you to move the cooker out for cleaning purposes and maintenance, refer to the rule book for more information
At 2:24 you say that an 8kw cooker WITH diversity applied is around 26 amps??
With diversity 8000amps /230v =34amps.
First 10amps then 10% of remainder 24/30% =7.2amps + 10amps = 17.2amps total with diversity.
