E-Calc is a free Android application developed by IGE XAO that provides a professional and comprehensive solution for electrical engineers and electricians. This app is designed to calculate complex electrical problems based on the National Electrical Code, making it an essential tool for all professionals in the industry. Unlike other electrical calculation apps, E-Calc returns code results including wire sizing, conduit sizing, fusing, overload size, ground and bond size, and much more.

The app offers a wide range of features, including a basic construction calculator that allows you to easily divide rooms for lighting in imperial or metric measurements. It also calculates any single motor and provides maximum overcurrent, maximum overload, minimum wire, minimum pipe, and minimum bond wire size. E-Calc can calculate any transformer size and provide KVA, FLA, pipe size, fuse and breaker size, bond size, and ground size on both primary and secondary. Additionally, it can calculate the allowable ampacity of any wire type and deration situation.
