Copper electrical wire and cable manufacturer Cerro Wire LLC, has introduced a powerful electrical calculations app for the iPhone and iPad, giving electrical contractors instant access to an easy-to-use, all-in-one tool for computing field measurements.
Electrical contractors can calculate conduit fill, voltage drop, and amperage all within a single 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 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.
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 is currently available for download for the iOS platform. Cerro Wire hopes to expand the app to Android at a later date.
