Cable Calculation and Selection Worksheet

As the final article on voltage drop and cable selection series, I am now providing a complete worksheet for cable selection based on the IEC standards 60228 and 60364-5-54. I created the worksheet in such a way that it could be printed with your company name, logo, your project, your name, cable number, load description and many more.

The cable data reference sheet is contains data from a particular cable manufacturer, consult your cable manufacturer for project specific values.

Some notes on the use of the cable calculation worksheet.

  • Cable data provided in here are based on a manufacturer's datasheet. Refer to your cable manufacturer for project specific values.
  • Cable calculation is based on IEC standards.
  • Load data is based on motor load and 3 phase. Modify accordingly depending on the type of load supplied by the cable.
  • This calculation is just a sample. It is always a good practice to verify the results.
  • I"k should be based on the short circuit calculation result. It is not part of this worksheet.
  • Please read the Disclaimer Statement before using this calculation worksheet.

The cable calculation worksheet could be found at the download section.


Design Stages

Successful projects were not developed overnight. They have undergone through several stages. Missing any one stage may have caused disastrous effect on the projects causing failure.

Conceptual Design
To develop your project ideas into a more tangible perspective.
Front End Engineering and Design (FEED)
To explore possibilities to enable better control on the outcome of ideas, getting the final result without delay but more importantly without overshooting your budget.
All ideas need to be developed at this stage of the project.
Detail Design
The final stage of the design aspect of your project. Only minor, unforeseen and uncontrollable by the project team need to be implemented at this stage.
Injecting radical changes at this stage could mean redevelopment of the project concepts leading to project delays and budget overshoot.
