Bussmann FC2 Available Fault Current Calculator Mobile App

Bussmann’s new FC2 mobile app calculates available fault current anywhere in an electrical system and creates NEC labels for marking service entrance equipment

Bussmann’s FC2 Available Fault Current Calculator from Eaton's Bussmann business puts added power into the palms of electricians and electrical contractors. It is the first fully-functioning mobile app that allows the use of standard mobile devices to calculate available fault currents, generate one-line diagrams and produce compliance labels for power systems without any of the associated fees – a significant savings in time and expense.

To use FC2, electrical contractors or engineers first choose between three-phase or single-phase system types. Users simply add the system components through the app, and it quickly calculates the available fault current and generates a one-line diagram of the entire system. The app also produces NEC® 110.24-compliant labels which clearly show the maximum available fault currents and the dates of calculation. Labels can be created as JPEGs and are pre-designed specifically for fast, trouble-free printing on most label printers. Users can even email labels and diagrams directly from FC2.

A sizing guide included in the app facilitates the correct sizing of fuses and conductors. FC2 users increase on-the-job safety – and save even more time – by using the fault current calculation in conjunction with the NFPA 70E table (hazard/risk category) method for compliant PPE selection.The mobile app is available for Apple® and Android® mobile devices. A web-based version of FC2 Available Fault Current Calculator is online at the Bussmann website.
