Cablesizer

Technical Notes

1. Introduction

These technical notes provide details on how Cablesizer is constructed, and in particular, the limitations of the sizing calculations. Firstly, it must be stressed that these calculations are for low voltage cables only (<1kV) and there is currently no support given to cable sizing at higher voltages.

Generally speaking, Cablesizer covers most of the common cable sizing applications for domestic and industrial scenarios, but does not currently cover any special cases. If you'd like a particular case included, please contact us at contact@cablesizer.com.
