Excellent, informative video thanks. We’re about to have our kitchen refitted and are swapping to an induction hob from gas and a number of kitchen suppliers and electricians have told us that we’ll need a dedicated 32Amp supply from the consumer unit even though we have an existing 32Amp cooker circuit with only our single electric oven on it. One suggestion we were given was to put the new Induction hob on the existing oven circuit and then add the 3.2kW oven to the kitchen socket ring main, hardwired. Now I’ve watched this and learnt about Diversity I know that both the new 7.35kW induction hob and 3.2kW oven (20.77Amp total) can be run on the existing 32Amp cooker circuit . Thank you

I honestly think they should get you to write the next edition of the wiring regs John👍🏻

Thankyou for the clear explanation and break down of the explanation into simple steps. The hidden humour of cleaning behind a 20 year cooker made me chuckle too.

Your method of teaching is absolutely first class every word you use has value and is not in the least superfluous to your explanation when setting out your examples etc I really do enjoy these mini lectures and the skill with which you impart your subject matter . By far one of the best you tube channels out there bar non on electrical matters . Thankyou for your effort on this channel which is reflected in your number of loyal subscribers .

My apprentice was talking about you today, said you were better than her college tutor. I do believe she learns far more from you than college....so thought I'd see for myself and I don't think she's up the good work

[GazzJ]

I have lost count of the times that someone has called me in to install a cooker and the salesman has told them it will need a 50a supply and everything upgrading. Haven't needed a supply greater than 32a yet. :) Great video as always.

As a building control officer with no electrical training I am so impressed with the explanations given in your videos. I very much appreciate your time and effort, you have explained clearly with clear understandable examples. I am not an electrician but feel more confident in my role with regards to understanding electrical work in domestic properties. Thank You .

Really helped me with my kitchen hob/oven install and working out the load with diversity applied. Thank you.

I did find your channel in the past with great explanation, but this just reminded me of the effort you go through to break down things! Keep up the great work!

As an old spark I wished I'd have had you as a lecturer back in the late 1960s when I was at college

[lukwal]

In my opinion you do best tutorials on British you tube about the science and practical things regarding electric work.

Well done👌

Just about to start a kitchen renovation, your videos have literally put me at ease and I now have a great understanding of the work that will be needed to be done and how it can be done. Fantastic!!

Love this channel. Always something to learn and I’m not a sparky!

[ThePach]

I love this video. Thank you. It's so frustrating seeing people on forums advocating 10mm2 cable with 45a MCBs for cooker circuits without any rationale.

[mikes]

This has been a refreshing albeit vindicating video for me, fantastic/straightforward and common sense view on the difference between the use of 4mm and 6mm size cable. Thank you John. 👍🏻👍🏻👍🏻

[SqwarkParrotSpittingFeathers]

Very informative as usual. I shall be placing on any consumer units installed a notice saying "in compliance with JW regs", as JW regs are more authoritive and clearly explained than the On Site Guide and BS7671:2018, lol.

[maciejtryka]

One of the best videos on domestic cooker installation, so many sparkies don't understand it and panic when coming to install electric range cooker- just dividing W/V and coming up with 16mm2 cable, not taking into account thermostats and energy regulators which allow for use of diversity factor.
The way its presented is so simple that every layman would understand.
Well done Sir!

[leea]

This has answered a question I've long wondered about. You're a champion, thankyou!

[yvonfem]

Brilliant John you have a fantastic way of explaining things I'm not a spark but I always find your channel entertaining and I actually understand it thank you

For me, this is the best site for electrical know how. I very much appreciate your knowledgeable, helpful posts. First class & very thorough👍
