Cable Calculator is a website plugin module with a simple and clean interface which allows users to size low voltage cables.  The module calculates the CSA based on current capacity, voltage drop and fault rating while requiring the minimum amount of user input.

Important: the calculator is designed to be added to websites and requires a subscription to our API service.  If you wish to only size cables, please use our main application by selecting 'Cable Engineering' on the site menu.
