Use

Use this tool for fast preliminary engineering estimates before detailed equipment selection.

Inputs and outputs

Enter the required technical values and review the compact result strip for the main calculated outputs.

Simple example

Change the default values to match a real project scenario and compare the result before requesting a technical review.

Limitation

Cable size is a preliminary estimate only. Final selection depends on installation method, ambient temperature, grouping, insulation type, permitted voltage drop and the applicable design standard.
