Utility tools: Cerro Wire LLC, a manufacturer of copper electrical building wire and cable, introduces its electrical calculations app for the iPhone® and iPad®, which gives electrical contractors instant access to an easy-to-use, all-in-one tool for computing field measurements.
At the touch of a finger, electrical contractors can calculate conduit fill, voltage drop, and amperage all within a simple mobile app. Using the conduit fill calculator, users can enter the type of conductor, the size of each conductor, the type of conduit being used, and the length of the conduit run, and the calculator will return the recommended conduit fill. For voltage drop calculation, users simply enter the length of the conduit run and the type of conductor, and the calculator will return the recommended conductor size based on NEC-recommended amperages. The amperage calculator simplifies an NEC amperage chart into a convenient calculator. Combining all three of these calculations in a single app, Cerrowire’s Voltage Drop, Conduit Fill and Amperage Calculator is a must-have for electrical professionals.
The app can calculate voltage drop for 120V, 208V, 240V, 277V, and 480V voltages, as well as 277/480V and 120/280V 4-wire voltages. Calculations work for THHN/THWN, XHHW, or USE copper or aluminum conductors. The conduit fill calculator applies to 14 AWG through 750 MCM conductor sizes, and works for EMT, ENT, FMC, IMC, PVC, Type EB PVC, LFNC-A, LFNC-B, LFMC, and RMC conduit types. The amperage calculator can handle 14 AWG through 1000 MCM conductor sizes.
The app has been successfully launched and is now available on iTunes. It is available for dual download for the iPhone® and iPad®. Cerro Wire hopes to expand the app to Android at a later date.
