Looking for a quick and easy way to size conduit per the NEC? Cerro Wire LLC (Cerrowire) created this app to help you figure out what size conduit to use for copper and aluminum building wire. Two calculators allow you to determine what is the maximum number of conductors that will fit in a type and size of raceway, or what size raceway is required for the type(s) and size(s) of conductors in your circuit. All results are based on the National Electrical Code®. The app can be used to calculate raceway size or fill for EMT, PVC, RMC, etc., with insulated and bare copper and/or aluminum conductors.
