Use the above tool to find a recommended cable size for your motor. Please choose the desired cable construction, Temperature rating and Voltage by clicking on the text. Then move the slider to the desired HP rating and click “calculate”. The configurator tool will recommend a cable size based on standard values from NEC 2011. Please evaluate all recommendations for your application.
All values given are calculated based on NEC 310.16 and are de-rated. For actual amperage consult your Motor/Drive manual and your local code restrictions. This guideline is simplified in order to select cable sizes. This document has no legal meaning, the interpretation of the NEC code has to be verified by the Authority Having Jurisdiction (AHJ).
