The 2017 National Electrical Code (NEC) updated requirements for marking the Short-Circuit Current Rating (SCCR) on machinery and equipment, now including marking the available fault current. Eaton offers a three-step approach to ensure compliance: 1) identify the range of potential fault currents, 2) specify and design equipment with appropriate SCCR, and 3) ensure the SCCR exceeds the actual fault currents. They also provide free tools for analyzing SCCR and selecting the right equipment.
