Thank you so much for this explanation sir. But i dont know why you didnt use copper cable for feeder 3, but rather used aluminum. I will be so glad if you can explain to me 11:21
1 sq mm Copper Cable Current Carrying Capacity: Copper cables with a cross-sectional area of 1 sq mm exhibit an impressive current carrying capacity of up to 30A, making them ideal components for electrical wiring
For three phase , P = √3 VI cos I = P/ √3 V cos √3 = 1.732 , V = 415 , cos = 0.8 If you multiple these three it will come 575 Similarly for single phase , without multiplying 1.732 .. You will get 184 for 215v . Hope you understand
Dear brother...
1 sq mm current capacity is 2.4 is totally wrong brother... it will carry atleast 10 ampere.
Very nice practical information. Thank you very much
Very useful vedio brother....i learned very basic information......thanks for video
I'm here again. Thanks for sharing it with us.
Very nice explained
Nice information
very useful & fast computation
nice one
Thank u for uploading this vidio 🙏
Helpful

thanks for the video and how do u cater for the voltage drop, installation method and the distance the cable is going to run through ..
thanks
super bro
The CB should protect the cable but how it protect it if the rated current of CB is higher than the cable current carrying capacity. Load current
Super bro thanks very clear ☺️😊 one small doubt it's will work bro i can suggest it for my client.
verrygood.I has a cable chart of Siemens&other mfrs.But after years of working this rule didn't come up.
Thanks

At 7:45 you multiple a power factor of 0.8 * 230. Is pf not 1 in single phase.
How to calculate derating factors of cables in cable trays
What about length of cable
Thumb rule formula required for 3&1 phase how it's came 575 &184
For three phase , P = √3 VI cos
I = P/ √3 V cos
√3 = 1.732 , V = 415 , cos = 0.8
If you multiple these three it will come 575
Similarly for single phase , without multiplying 1.732 .. You will get 184 for 215v . Hope you understand
Bro single phase power facter is always 1 not for 0.8 that is 3 phase 😮
Come again Sir
1 sq . mm cu wire can carry 12 ampere not 2.4 a
12amps withstand only not carry

Very nice explained
Nice information
Thanks
