Description
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
- Create and send a label via email for marking the available fault current on service equipment (NEC® 110.24)
- Size fuses and conductors for service, feeder, and branch circuits.

Very Easy I like how this app flows. The label feature is a plus.

Great app This is easier to use than my electrical design software for determining fault currents. I've used the cooper bushman 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.

Neat little calculator for checking fault current along a single system branch. If the app allowed you to create branching one line diagrams, it would be worth paying the subscription. As the app is now, you have to use paper and pen alongside this app any way to create a comprehensive system diagram, so the benefits of saving projects and sending system diagrams are entirely lost.

It wants you to fill in every field including aic. It's just a form not a calculator.

Will not allow me to log in. tells me to check internet connection or try back later.

Can't enter data 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.

Limited MVA for transformers in both the free and subscription versions.
★☆☆☆☆Michael Furtak· Jun 26, 2015
Inaccurate and impractical 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.
