Engineering Tool

Ampacity Calculator

Estimate corrected current-carrying capacity for low-voltage power cables using installation method, conductor material, insulation temperature, ambient temperature and grouping factors.

Correction FactorsAmbient temperature and grouping are applied automatically

Cu / AlPVC or XLPE with practical installation options

Minimum CSAFind the first size that satisfies the design current

What this tool does

Use it for preliminary engineering checks and product guidance. Final design should still be confirmed against project standards, manufacturer tables and actual installation details.
