BREAKER AND CABLE SIZES FOR ELECTRICAL CIRCUITS.

How to select the correct size breakers and cables for your electrical circuits. This video will introduce you to the steps needed to calculate maximum loads on a circuit; how to use charts to determine the correct circuit breaker for the load, and how to select the right size of cable for the job. Avoid the dangers of installing cables that are too small and give rise to fire risk, avoid over sizing cables and wasting money on excess copper; the right size matters. Use the tables to ensure that the circuit demands are properly balanced and will function safely and correctly. With just one easy to use formula, this video will enable you to plan jobs more efficiently with the confidence that it has been done correctly according to the Wiring Regulations. Once learnt, remembered for life.

When you fully understand something it is easy to explain said Isacc Newton. Your explanation was simple and complete. Thanks

[jeremykemp]

9 times out of 10, yt influencers give out incorrect information. This guy does NOT.. Excellent stuff sir . Sub from me

[markandrews]

I can't begin to tell you how grateful I am for these videos although I retrained 7 years ago as a older student know 53 they give me a much better understanding I am now confident enough to help some of the younger apprentices with issues or just show them your videos keep them coming matey 👍

[souljimmy]

Finally someone has explained the actual calculation of what we were trying to learn 👏

[johnh]

You have saved the day once again mate.
I was sweating over this theory on a training course and its a relief to now understand it. Thanks to your excellent communication skills. 👏

[jamesbradley]

Thankyou described it in a easy to understand, in the past I have looked at books on electrics, and they made it sound so complicated, but with your explanation I got it straight away, once again thanks

[mohammadtahir]

If i am not wrong, there is not even a channel like yours...
It is helping me...
Thank you for everything and may ALLAH(GOD) bless you...

Thanks a lot dude. Just about to complete my engineering apprenticeship and now wish to base my career from an electrical bias. These theories aren't so intimidating when broken down and structured as well as you have demonstrated here 👍👍 will be sure to watch more. Thanks again

Hi great video but ai am confused you say at 8:32 there are 2 entries for 32a when there are 9, & 6 of them meet the installation method 100.. am I missing something obvious this is a little old not as page 82 now.. your help here would be most appreciated.. Thanks

[shiamjad]

i learnt more from you than from my 2 years at the college... keep the excellent work up

[matthewdaniel]

Master your videos are superb. I'm not yet an electrical engineering student but I'm about to be, watching your videos is pretty good for a lost sheep. After tons of research this piece just made my day.

[ngqabuthongwenya]

Thank you so much, your explanation is perfect. In class they gave us handouts stating the steps of finding the cable size with these Ib, In, Iz symbols, never understood the meaning of these symbols, and now that i viewed this well explained video everything became clear

[hingninwong]

Thanks useful video. For the video of playing at 8:57, may I ask why not choose cable size of 10mm/4mm?

[jesswimbledon]

Thank you for this video, something what i thought id never get my head around made it very easy by watching this. once again thank you

[mossmm]

Thanks once again for well presented technical material in the subject of electrical calculations

Kindly keep them coming

Thanks

[aarondunlop-pk]

Fantastic video. What would change in the calculations if it was on a tt system. ?

[robertpeters]

Fantastic explanation really informative. Completed a domestic installers course with a well known training centre and this is great to keep my knowledge from rusting up. Great stuff and easier to understand.

[CosiMonger]

Excellent video. I learned a lot about choosing the correct wire size and fuse to be used.

Hi Dave, I recently completed and passed an excellent domestic electrician course at EC4U in Ditchling. Your video series is a superb “old-school” reinforcement of these key principles and in some cases has offered an even clearer explanation, or at least a different perspective on the same learning points. Being an older learner who has recently changed to the electrician career, this series has been brilliant. Thank you!
