Selection of cross-sectional-areas of cables is certainly one of the most important tasks of the design process of an electrical installation as this greatly influences:

  • the selection of overcurrent protective devices,
  • the voltage drop along these conductors
  • and the estimation of the prospective short-circuit currents

This chapters details the different steps and methodologies for conductor sizing. And the specific recommendations for neutral and Protective Earth (PE) conductors sizing.
