), you may find that a slightly smaller cable cross-section is technically permissible, saving on material costs.
The standard follows a systematic three-step approach to determine the final permissible current: Calculate the Adiabatic Current ( IADcap I sub cap A cap D end-sub
) for different conductor and insulation materials like XLPE or PVC.
