The free Ampacity Calculator app recently released from Cerrowire helps electricians determine the ampacity of conductors in conduit, cable, or directly buried based on the National Electrical Code. Within the app, dropdown fields allow the user to select the conductor type, wire/cable type, conductor size, ambient temperature, and the number of current-carrying conductors. These inputs, along with the number of parallel runs, are used to determine the ampacity — or maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. According to the company, this data helps electricians choose the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating. The free tool, which is available in both the Apple App Store and on Google Play for smartphones and tablets, is also available as a web-based tool from the manufacturer’s web site.
