Software for Electrical Design | Cable Sizing Calculations

ElectricalOM is the ideal cable sizing software

Cable sizing calculations for phase, neutral and earthing conductors are based on the following criteria:

  • Source characteristics (earthing system, fault levels etc)
  • Load current
  • Voltage drop
  • Short circuit and Earth fault currents
  • Protective devices disconnection time
  • Cable energy withstand based on the Protective devices let-through energy
  • Earth fault loop impedance checks
  • Use of earth fault protection/RCD devices
  • Touch voltage limit
  • Unbalanced load
  • Power factor
  • Harmonics
  • Motor starter type (direct on-line, star-delta, soft-start etc.)
  • Motor starting current
  • Motor minimum starting voltage
  • Motor contribution to short circuit
  • Integrated AC & DC Systems
  • DC Battery Characteristics
