clearer&better than the information I search online for an hour combined.

[shubhammishra]

you are first person who defined completely.

[Quote-SJ]

You have very good understanding of each and every factor....superb have been working in industry as an Engineer, I want read articles related to industrial technology can you please suggest me any source....
Thank you... May God bless you..

[rajeshshakya]

Very simple explanation cleared all my doubt regarding cable sizing calculation.
Thanks for sharing.

[behrozeshabir]

Thankyou sir make lectures in sequence so we can gain more. Thankyou again

[powerengr.]

Appreciate your Knowledge and effort to help needfuls.. 👌

[mohdwajidali]

One of the best video i saw for cable sizing. Sir kindly make another video with some example..
Also how we can calculate short circuit for villas and mall where we have lot of pumps and AC machines. Here you took 50000 amps as a fault current and 0.2 sec time. The same will apply for homes and malls??
Thank you for the good explanation...
Regards,

[manishmonci]

good day to you sir, if you could make a video citing an example of a load with all the calculations of cable sizing, breaker sizing, bus bar and traffo sizing so we can get an over all view, in interviews they ask us to make an sld giving a load as an example and ask us to choose the breaker size and ratings for all equipments coming in it. well appreciated and keep up the good work

[technicalgyan]

Nice informative video sir !!
Sir, can you please make an elaborative video on Ampacity of the cable. Also one more request... That can you provide us these calculations in an excel sheet as a tool, so as to generalized the sizing of thecable calculations, by just providing certain inputs parameters

[mohammadsaleh]

Thank you for sharing this information. Keep up the good work brother!

[shashankkumar]

Nice. Video sir...please make video on ups

[RohanKumar-hjgb]

You've explained very well appreciate it!

[tamizhthaaragai]

Great work. God bless you. Also if possible please show one actual cable sizing for a 400v 15kw motor (just an example) with Cu/XLPE/SWA/PVC cable run in a cable tray

[powerengr.]

Amazing briefing method.. Admires your's efforts boss.. 👌

[keyable]

Could you pls provide a video where "Number of cable runs" are explained? I could not understand this term

[ayarottilsandeep]

Thank you so much, this was the video and explanation I was looking for. Thanks for such an amazing educational video.
I have 2 doubts which I feel like to ask you, and it would be very kind if you will answer.
1st, after a lot of search I found a formula for voltage drop as per BSI 18th edition, also seen in several electricity regulations of GCC countries.
The formula you mentioned in your video also can be derived from this.
Voltage Drop (not in%) =
=((Load current X length X (voltage drop per unit length per amp)) /(1000X no. Of runs)

Now here the voltage drop per amp per unit length can also be written as (R Cos theta + j X Sin theta), so till here it's very clear, but in the video you mentioned a √3 which is obvious for 3phase load, but it's not used in the formula I mentioned, can you explain why???
2) as per motor starting current 5 to 6 times of full load current, so for example let it be 10amp FLC and Staring current would be about 60 so, is that a cable of minimum 10mtr length shouldn't be choose 16sqmm cable instead a 4sqmm ??
Even though the starting current will persistent for 1 minute I belive??
Kindly give a appropriate reply.

Thanks for such informatics videos.

[sukhveersharma]

Very much useful video. Please upload a video for designing of 400/220/132/33kv substation.

[sarbrassahamed]

It will be more useful if you calculated for voltage drop criteria also.. anyways good and clear job❤

[mukhtaralam]

Thank you for this video Also if possible please show one actual cable sizing for a 400v 1kw to 400Kw motor.

[venky]

superb video... thanks for your hard work....
