HP Configurator

Use the above tool to find a recommended cable size for your motor. Please choose the desired cable construction, Temperature and Voltage rating. Then select the desired HP rating and click “calculate”. The configurator tool will recommend a cable size based on standard values from NEC (NFPA70). Please evaluate all recommendations for your application.

All values given are calculated based on NEC (NFPA70).

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).
