    Hello Sir bhardwaj: First time have seen such beautiful explanation on electrical designing on CZcams otherwise there are lot of stuff on CZcams related to it but i like the you taught. Sir it's a request that please make complete electrical design and calculation videos for electrical projects on construction site. I want to learn this from your channel. so please do it.
    Stay Blessed

    Why you devided the the full load current with the derating factor,
    It should be multiplied

  • @roshanmaskeyshrestha8669
    @roshanmaskeyshrestha8669 Před 3 lety +1

    hello sir, i didn't understand on base on full load current calculation there it came 347 amp and u selected - 3 core x 120 sq.mm. you could provide us pdf file too. thanks for sharing the useful video

    • @user-nb3mr1ky5y
      @user-nb3mr1ky5y Před rokem

      According to 120 mm sq, I thing that must be cu cable

  • @vinayaksera
    @vinayaksera Před rokem

    if we always select short circuit current rating of Protection device (as you mentioned a CB rated for 50KA for 0.25 s), we will always end up in cable size of 300 sqmm considering same type of cable whenever the load after derating is lesser. What should we consider the short circuit current in that case as if I employ a cable of 300 sqmm for a 55 KW motor which is placed at 100 m distance and protected through ACB, i will lose money every time.

    • @electricaldesigningbasics
      @electricaldesigningbasics  Před rokem

      Thanks you very much for watching the video.. answer: you have take your system fault level & your relay setting..50KA is breaker capacity...that's the very high range..u have calculate according to your system.

    • @VipinSharma-qr7yo
      @VipinSharma-qr7yo Před 9 měsíci

      It should be considered only for HV cable size calculations for LV size we should consider only ampicity and voltage drop criteria..

    how can put the i,squre value 50000 in K(short Ckt Constant Value)if we have calculated full load current 347amp

    • @electricaldesigningbasics
      @electricaldesigningbasics  Před 2 měsíci

      Thanks for writting. Dear it's for max fault current. Either we calculate exact fault current or considering max value.

    • @electricaldesigningbasics
      @electricaldesigningbasics  Před 2 lety

      Hello dear, thanks for watching the video. Regatding your query , we need to get current & length for calculation. Basic calculations will be similar some load profile will change.

    Sir, So generally cable size selection full load ke anusar hona chahiye ya fir short circuit current ke anusar hona chahiye?

    • @electricaldesigningbasics
      @electricaldesigningbasics  Před rokem

      Generally k liye...hum 1sq.mm = 1amp...for aluminum cable. We have keep the length in mind...& cable maximum current capacity mentioned In catalogue should be higher than SC.

    How to select 3C and 3.5C size of cable and where it can be used? Also 3.5C and 4C difference?

    • @electricaldesigningbasics
      @electricaldesigningbasics  Před 11 měsíci +1

      Dear thanks for watching video..
      Now, coming to your question, the basic difference btwn 3C & 3.5C is of neutral...if it's 3ph balanced load then half size core of neutral as compared to phase is sufficient....
      In system where there is high neutral current or some OEM suggest due to equipment design then we use neutral as a full core similar to phase. I:e 4core.
      When power is fully supplied through UPS or through isolation xmer, the 3Core is sufficient neutral not required limiting use to 3ph load nly.
      Hope it resolves your doubt...if still persists, online classes is starting soon where full designing course will be done one to one.
