On Site with Matt Connecting up a new Cooker and Testing the Circuits Earth Fault Loop Impedance Zs

How to as electrician Matt is wiring up an new cooker in his latest on site with Matt video. Matt connects a new 6mm2 cable to both the cooker outlet plate and the back of the cooker. The video also includes safe isolation, polarity, the earth fault loop impedance tests and shows you how to wire up an electric cooker.

Sadly I (GAZ) deleted the footage when Matt went back with his torque screwdriver to the cooker connection plate.

So the previous cooker had no cpc connection to the earth terminal, good job Matt turned up when he did.

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 !!!

Clear concise and informative. As a trainee installer I find these types of clips very useful

[nosferatu]

Great video and nice to see that there are still craftsmen in this trade. Nice workmanship.

Only a man of experience slides his stripping knife towards his fingers with force like that.
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

I came here for Matt, not disappointed 👍👍👍👍👍

[michaelcostello]

Thanks. Nice to see the earth fault loop impedance done on cooker body also

[rbemuscle]

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 🙏

[Mark-gfyw]

Must admit, I had to shut one eye watching you cut the sheathing. Much safer to use the cpc 👍

[simonschertler]

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

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

[jackseko]

Thank you for the work may God continue to bless you

[paulwarner]

What do you do with the loose cable behind the cooker. Is it OK to just feed it back with the unit, or do you have to use a heatproof shield?
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.

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

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

[AntonyoKnight]

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

I was going to try and fit my electric cooker when I bought it next month, after watching this I will pay an electronic to do it lol.
