MATCHING CABLE SIZE TO CIRCUIT BREAKER SIZE. How to select the correct sizes for safety and function

How i understand it is, we use the smallest permissible wire size to reduce cost, increase ease of installation, and easier interface with components.

Always informative.

Hi Sir, how do we measure the cable length? Is it from the consumer unit to the intended switch or socket outlet? Thank you.

Thanks

Wow! This is very informative, thanks for sharing it with us. It worth it and the best tutorial on the topic for me...dl

Fantastic and educational. I’m 53 years young and enjoy learning this amazing trade. You give very practical real world advice.

thanks

If the shower draws 39A wouldn't a 40A breaker be too small? Considering that it is a regular practice to size a breaker at 125% of the continuous load, or to only utilize %80 of a breaker's capacity?

👍

why is multiplied by 100watts please

thank you

This channel is the best… you discuss real life problems precisely and accurately… can you do a video on SDP sizing and selection

These vids are great. So very helpful. Thanks so much.

Your videos have been a godsend to me. I have just finished level 3 (8202). Now I have 18th edition to do soon. Thank you very much for the videos !!!

Dave, if I have to drive 200 mile to come to your class and learn from you I WILL!!! Just tell me where is your college! I spent at least 3 years in college and lot of short courses in London but never ever meet someone like you to explain easy and clear so people in every level can understand it so easy!!! I can not thank you enough!! THANK YOU SIR!!!

Hi , great video , however when you choose cable for Cooker circuit, you showed in your example shower circuit instead of cooker circuit.
My question is if it was actually a cooker circuit that would draw 7KW then woudnt you apply diversity before choosing the circuit breaker.
Once again thanks for the video

This vid really benefitted me. Thank you

Thank you

Another great Video!!!

It's scary to think that some one who is presumably qualified and experienced to sign off other work doesn't have a clue of what they are doing, to say it's illegal also is worrying, good content mate

Thanks Dave.

Super vids Dave.

This content is absolutely fantastic and you should be up there with the highest views and subs but......you don't drive a Tesla to site and bombard us with ads and marketing.

I prefer you guys as you are....👍🤝

Brilliant as always
