E-Calc USA

E-Calc USA is an electrical application for calculating many common electrical problems. This app is an essential tool for all electricians and electrical engineers. Unlike other similar apps E-Calc not only calculates simple formulas but returns code results including wire sizing, conduit sizing, fusing, overload size, ground and bond size and much more based on the National Electric Code. The features of this app are too long to list but here are a few of the key ones; - All calculations are saved to device and can be shared or printed. - Create unlimited projects, contacts and suppliers. - Universal app runs on iPhone, iPad, and Mac with dark mode support. - Create custom panel legends and print to scale. - Calculate any box fill situation in cubic inch or milliliters. - Create material lists that can easily be ordered or searched from within the app. - Calculate transformer size and get FLA, pipe size, fuse and breaker size, bond size, on both primary and secondary. - Calculate any motor load and get maximum overcurrent, maximum overload, minimum wire, minimum pipe, and minimum bond wire size. - Calculate the allowable ampacity of any wire type and deration situation. - Calculate maximum number of similar sized wires in a given pipe size or mix various sizes and types of wire to get percentage fill in any pipe type. - Calculate light fixture spacing in feet and inches or in metric. - Calculate required bonding and grounding sizes. - Easily calculate complicated voltage drop calculations. Get results for percentage voltage drop as well as maximum lengths of runs and wire size. - Calculate recommended torque settings for all varieties of lugs and terminations. - Convert many common units with the built in conversion calculator. - Calculate linear expansion of conduits. - Ohm's law calculator. - Strap spacing calculator. - Voltage unbalance calculator. - Find NEMA codes and specs of receptacles.
