Hello, Please tell why ahve you taken Full Load Current =774 A, when rated CB Full Load Current Value was 721A and previous Ampacity Calculation Full Load Current for 4 runs was 876 A. Please tell if its an error. Sir, please show another video of breaker Sizing calculation with a heavy motor with all the calculations for Cable Sizing, Breaker sizing etc for a simple HT /LT Motor with an SLD.
Please specify: 1. Why No Voltage drop has been considered due to motor load starting current? 2. Why transfer full load was not considered ? After period of time more load may be put upto transfer full load. 3. Power factor shall be less than 0.9 as depends on nature of load. Regards
The short circuit current will get devided into 4 cable runs, so your system short circuit current per cable will be 30/4 kA and your calculated cable short circuit capacity is 34K.
Sir, we devide derating factor to the base current or multiply , some confusion becuse in some RUclips video they divide but you multiply , Kindly clear it
EYE OPENER PLEASE CONTINUE WITH THE GOOD CAUSE
Thank you for this. Very good informative video!!
Your video is very good and informative
Thank you so much for your information.Can you explain differences to wcl and armoured cables ? How to select water cooled leads ?
For more clarity 4 runs per ph. that's means 4 x (4C x 240 SQMM) + G. Thanks for your effort.
Please tell me what power factor shall be consider for DOL motor, VFD drive motor and for feeder.
great.thank you sir
Nice vdo sir can you do it same for Size of earth wire ,electrode for building and house...calculation

Please tell me the effect of ambient temperature, short circuit current, soil resistivity in cable sizing.
Dear sir
How you find the value of sin value in voltage drop formula
The short circuit current will get devided into 4 cable runs, so your system short circuit current per cable will be 30/4 kA and your calculated cable short circuit capacity is 34K.
whats stands FLI for.?
Sir, we devide derating factor to the base current or multiply , some confusion becuse in some RUclips video they divide but you multiply ,
Kindly clear it
Bcoz already cable size is fixed so we can't increase the cable size we can increase the run of cable
The values should be increasing in order .
If multiply it should be more than 1'some number
Sir sorry, I have question in cable sizing.
What is the meaning of no of runs?
Example:
5R/3.5C/240sqm/XLPE and
1R/3.5C/25sqm/XLPE
Thank you Sir
Please explain cable schedule
sir what is dyn?
Thanks
Thanks dear
Hindi main ...new videos karie..sir
Hindi
Ok bro i will make hindi version very soon
How full load current becomes 774A instead of 729A in voltage drop formula?
Yes you are correct for voltage drop calculation only consider full load current 729A
Plz hindi
