The Motor Pro App is a utility application developed to assist electrical engineers and electricians with the task of connecting electric motors according the National Electrical Code (NEC). This application is designed to look up the rated Full Load Amps (FLA) for Single Phase and Three Phase motors based upon Table 430.248 and Table 430.250 of the NEC respectively. Using this, the utility application then sizes the minimum breaker size needed based on a multiplier that is user adjustable in the range allowed by Table 430.52 of the NEC. The utility application then sizes the minimum conductor size and conduit size, according to Article 430 of the NEC, required based on the type of conductor insulation and type of conduit specified by the user in the settings. Also displayed, for information purposes, is the ampacity and conduit fill of the calculated branch circuit.
