Setting of instant short circuit tripping of C.B/ selection of circuit fuse

Calculation of instant short circuit tripping of circuit breaker is based on following inputs:

  • Voltage(L-L)
  • Voltage(L-N)
  • Instantaneous Short-Circuit Triping Set
  • Accuracy
  • Cable Size
  • Cable Material
  • Actual Length of Cable

And according to what you select or choose, result of maximum length of cable for your tripping setting is calculated. Selection of fuse is based on circuit wire size input (1,5mm2 – 70mm2).

    Jignesh Sir,

    My sincere thanks to you for this amazing spread sheet.

    i would like to bring to your attention to just one point in this spreadsheet (calculation of voltage drop and cable size for motor / elect. load) by taking an example.

    If you consider a 7.5kW (an example) motor only load, at 80% efficiency, the cell I8 gives ‘consumed load’ as 6.0kW (lower than the motor output rating, as a result of multiplying output with efficiency instead of division) and this gives current values that are eventually calculated on this 6.0kW (cell I8) which would be lesser than the actual values we are hoping for.

    Please see if this helps so that your spreadsheet still stands out the best among others out there

      Jignesh Sir /EEP team,
      I realised that i have posted this one wrong thread. Please excuse me for my doing. The feedback was intended for cable sizing program spreadsheet as mentioned in the second paragraph.
