Sheet: Cable Size Calculation

A robust calculation sheet must address three fundamental constraints: The cable must handle the full load current ( Ibcap I sub b

It=InCa⋅Cg⋅Ci⋅Cdcap I sub t equals the fraction with numerator cap I sub n and denominator cap C sub a center dot cap C sub g center dot cap C sub i center dot cap C sub d end-fraction Factors include: Cacap C sub a : Ambient temperature Cgcap C sub g : Grouping of cables Cicap C sub i : Thermal insulation The required area in mm2m m squared can be estimated using: cable size calculation sheet
