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
If the current in the main incomer is 132.7Amp then why did you take the mccb rating of 180Amp .. should not it be closer to its rated current ? Same goes with other mccb s too!!!
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
Very useful vedio brother....i learned very basic information......thanks for video
I'm here again. Thanks for sharing it with us.
Very nice practical information. Thank you very much
Dear brother...
1 sq mm current capacity is 2.4 is totally wrong brother... it will carry atleast 10 ampere.
Very nice explained
Nice information
Thank u for uploading this vidio 🙏
very useful & fast computation

Where do you get 2.4 and 1.4 value Is it in the catalog or you just take random no
Nope, its not random value.
Normal standard amps ratings for copper 1sq.mm is 2.4-2.5amps
Aluminium 1sq.mm is 1.4-1.5amps
Thank you
nice one
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
Why change over 16mm2 cable to Al cable
Super bro thanks very clear ☺️😊 one small doubt it's will work bro i can suggest it for my client.
Helpful
At 7:45 you multiple a power factor of 0.8 * 230. Is pf not 1 in single phase.
super bro
verrygood.I has a cable chart of Siemens&other mfrs.But after years of working this rule didn't come up.

What about length of cable
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
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
How to calculate derating factors of cables in cable trays
Thanks
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
