About Fault Current Calculator
Eaton's Bussmann Series FC2 Available Fault Current Calculator application is an innovative tool developed for contractors, engineers, electricians, and electrical inspectors. This tool can be used on the Bussmann website or out in the field on a mobile device for those needing a quick and simple way to determine available fault current.
With this simple tool, users can:
- Calculate available fault current on single and three-phase systems
- E-mail and print a label for marking the available fault current on service equipment (NEC® 110.24)
- Size fuses and conductors for service, feeder, and branch circuits.
This application, calculations, and other information are intended to clearly present technical information that will determine the available fault current at specific points in an electrical system. Bussmann reserves the right, without notice, to change this application and/or discontinue/ limit its distribution and/or availability.

This app is very intuitive and easily calculates fault currents for a one line drawing. I like the look and feel as well.

I purchased a Samsung galaxy 5 and when I downloaded this app I found that there's no decimal in the calculator for the impedance value, so please fix. I loved this app on my previous smartphone. 2/25/2015 Samsung updated their software and now the app works like it should!

Equipment x/r ratios is not taken into account in calculations. Hence, highly inaccurate calculated fault current values. Also, the app is limited to one (1) source only, does not provide for creating real world radial single-line diagrams and does not factor in short circuit current contributions from motors and generators upstream.

Excellent app. Needs the decimal issue (lg g2) fixed. Quick easy, accurate. Its a keeper.

I've an AT&T Samsung Note 1. Installed software, tried to use it on a 3 phase circuit. When I get to entering kva and voltage, app does not bring up keypad. Long press on entry field does eventually bring it up, but app erases my entry when I try to move to the next field. Uninstalled.

This is a great app. I like this better than the online fault calculator Bussman used too provide. See you at NTI in Ann Arbor for the Tuesday night presentation!

This is easier to use than my electrical design software for determining fault currents. I've used the cooper bussman guide as a method for calculating fault currents before. Thanks for automating it. It even generates a PDF with all the fault currents labeled. Make it movable to the SD card and allow me to add motors and I'll give it 6 stars.
