A really well presented and informative video, thank you.

Thanks for a clearly explained video. Just a point to remember when referring to a six millimetre cable it refers to the cross sectional area of the copper and not the diameter of the copper wire. Back when I started in home renovation, I would measure the copper wire with a vernier and then wonder why 6 mm was not the diameter ? Of course not - 6 mm refers to the area - it should be written 6 mm2.

Interesting. I hadn't realised just how much running cables through insulated walls makes to the amperage rating of the cable. It's definitely, something to keep in mind when adding insulation to existing walls, ceilings etc.

Great video. Taught me more in 15 minutes than my place of learning did In 3 hrs.

I am an electrician ,and on cookers you should allow for diversity , this is an allowance in the electrical ie regs, that means you would never have the cooker on full load ,talking the full 10kw while cooking ,( every oven and ring on full power) this means a 32A CB would be OK with 4mm cable for a short run and 6mm for a long run of cable.

very useful, easy to understand, and answered all my questions. thank you so much.

Clever & superb presentation.

One of the best and easily understood tutorials I've seen. Absolutely excellent 👏

Great videos, explain them clearly for all to understand 👌

I come back and rewatch this video again to remind myself, great video thank you

thanks for the upload very informative

Though I am not an electrician by profession but I have been in the power industry for 5 years now. It is an excellent video for learners.

The best I had ever seen too much worthy . God bless you bro

probably the best instructional video out there. thank.

Thanks for explaining this very clearly in this video. God Bless

Thanks so much for helping me from south Africa clear and simple👍🏾

Need more explanation; Good video, kindly upload one video on, how can we calculate Short Circuit of cable.

Good interesting video 👍👍👍

Another brilliant video.. Great stuff

I like this simple approach to calculating the design. I can't see a problem with using cable that's over-rated at is has less resistance and can cope with future changes to circuit usage. Diversity is an optional consideration if you don't want to spend too much on cabling etc. but it takes no account of future usage, so having larger cables is fine if you want to pay for it.

Great Video. Thanks for taking time out

Excelent info and concise! Thank you!

Very informative, really good explanation. Thank you.

Very helpful video. Thanks for your time to put this together

Helpful video. I'm level 2 electrical installation student . Can't wait to become an electrican .

Informative video about cable sizes

Howdy. Nice presentation of rating the thermal overload case. There is, however, another equally important aspect. The short cicuit case. There must be enough "short force" feeding the breaker to enable fast breaking (=magnetic triggering) of the breaker. In my location the power companies will provide information of how much short current is available at the service cable junction. From this point forwards one must calculate the short current at the most distant appliance or socket and choose a breaker that will fast trigger. If the short current is too low to deliver fast triggering the short current will flow until the thermal breaking happens. The socket wiring will run way too hot and there is a real fire hazard present. Regards.

Excellent explanation. Thank you for this educational video.👍👌

Hiya. I'm enjoying your videos Buddy. Just thought I'd mention it, as you did choose to use a cooker as your example. Don't forget to apply diversity as it is highly unlikely to ever reach its maximum demand due to the thermostats in the cooker rings. In your example (44 A) it would be the first ten amps (10 A) then 30% of the remaining amps (approx. 11 A) PLUS 5 A if there's a socket outlet on the cooker isolator. So, your 44 A has gone down to 26 A. The next MCB up from that is a 32 A. I'd still use 6mm cable though.

thanks to share the power cable information for tips . as an wire and cable making supplier in China that we learn a lot from your channel

Good video Though... Thanks for the tips and keep the good job

Thanks for your effort and a neat explanation for the beginners.

Sir thank you very much for the very clear explanation tutorials on how to calculate electrical wiring.

This guy is amazing how hi explain to the people

Thank you brother can you please help me with this knowledge I'm said from Zanziber in Tanzania

great information and thank you very much for that.

excellent video and very well explained I ve learnt more from home electrical wiring thanks to your video

Thanks for sharing it help a lot God Bless

Great video. Thank you for taking the time to make it.

very thorough and scientific.. learnt a lot.. got me thinking a lot more :)

A very simplistic look at the cooker circuit, you need to take diversity into account as the load is thermostatically controlled and therefore wouldnt pull the full load all the time.

Excellent video, Thank you.

Very clear and informative video! Thank you!!

prosto i konkretnie....tak trzymaj

I need to be calculation test books .any advice .Thanks brother 🌹

You have explain the calculation to obtain circuit breaker amp size and from there, select the cable size based on the table. But, I am curious about the calculation to obtain wire size. Why using 1.5 cable for ac for for example can cause it overheat. What is the maximum by calculation for current to pass through wire certain size.

Very important to use the right size of cable for the proper job :)

Brilliant video, very informative. Thanks!

at 1:15 talk about cable size 6mm, 2.5mm and 1.5mm. Iit should be read as 6mm square, 2.5mm square and 1.5mm square instead. Many thanks for this video!

This is quite a broad topic. You managed to explain the most important parts, excluding the formulae. For heavier loads we (central Europe) usually use 3 phase circuits.

Brilliant video.well explained!!

It was very useful, thank you :)

Very nice explanation...

what id you have a cable that is clipped direct and say runs through conduit? which value would you choose for the maximum current ?

Congratulations sir.

Lovely easy to follow vid. Thanks!!

One thing to remember regarding cookers... If it is a three phase connection than that 44 is divided by 3, which means you can connect each of the phases separately and the cable size does not have to be bigger than 2.5mm and size of three breakers collectively has to be 20 Amps each (44x1.25=55÷3=18.33)

very good mate well done, this will really help people

cool music at the end, very useful info, thanks

Very nice video sir thanks from Pakistan

No mention of diversity for the cooker. Nevertheless very effective and easy to follow video. Well done buddy.

Thank you for yoir explanation, I only have one note: When you get the current you divided power over voltage without the power factor.. it should be P/(V*pf) so the current will be 48 A , then you should select a cable size according to that.

Simple presentation but accurate

your explain very excellent thanks lot

You are The Man ...many thanks.

good video

Simples to follow great

Thanks for the clear explanation

Sir, can you make a video on calculation of electric load for a colony and how to select transformer for that colony?

Beautiful explanation boss

Very useful.. Thank you so much, from Mizoram, Aizawl

that book would be a good investment.

Thank u,, very clear explanation

Thanks for the video. Can you please change the music? Something more pleasant to the ears?

Great video, easy to understand.

Will a modern stand alone single oven work off a 16 amp circuit or do you need to charge out the circuit breaker on the consumer unit for a 32 amp circuit breaker ? Thanks.

Dankie/ Merci!

You forgot to take into consideration diversity, so take the first 10A and 30% of the remainder = 10 + 11.33 = 22.4 A approx , so theoretically 2.5mm would suffice if on a type B circuit breaker, 4mm to be safe. ( 6mm cable comes from the old days on semi enclosed fuses - where the correction factor pushed up the requirement for a larger cable)

Great video.... very helpful thanks

Thank you 😊

I like your work

Thank you for a very good presentation. I am quite stunned about the wire size. Here in Denmark for a cooker it would be 3 phase and 400 V. The calculation would be like this: 10000 W / 400 V x 1,73 (square 3) = 14,4 Amps This will eventually lead to a 2,5 mm2 if it is not placed to hot. Quite a difference! It would be fused with a 3 phase 16 amp.

i now 1mm cu wire can hold max 8 amp without voltage drop 0.05% in lenth 100 meter and don't get hot so (1mm 8amp) , (1.5mm 12amp) , ( 2.5mm 20amp) , (4mm 32amp) , (6mm 48amp) , (10mm 80amp) , (16mm 128amp) and thanks for your great video.

That book is useful I'm gonna have that book but I would like you to explain more about that book Thank you, Sir👨👨👨

very helpful thank you.

sir good explain

Could you please make a video about series or parallel circuit connection of led downlight? It will be very useful for everyone

think you very much

Wow ....wonderful!!!!

great video, that was big help to me .... BIG LIKE
