SSCR Applications and Codes for OEMs

Short Circuit Current Rating Applications and Codes for OEMs

Short Circuit Current Rating Applications and Codes for OEMsIt’s more important than ever to understand SCCR. The publication of the 2017 NEC includes several SCCR requirement revisions. 

Join us for three and half hours of training on the importance of overcurrent protection, short-circuit current ratings (SCCRs), and compliance with the National Electrical Code (NEC). And enjoy lunch as you learn.

This Bussmann® session will address overcurrent protective devices, industrial control panels, and UL 508A Supplement SB, providing an overview of SCCR determination and achieving a higher SCCR. This training will review SCCR strategies and industrial components that can result in higher assembly SCCR and save panel space.
