The Cooper Bussmann, St. Louis, Selecting Protective Devices (SPD) publication has been expanded and updated to the current codes and standards including the NEC 2008 and NFPA 70E 2009 requirements. This educational tool, used throughout the electrical industry, provides application information for overcurrent protection.

A valued resource throughout the years, this reference guide has now been expanded with detailed explanations of selective coordination, industrial control panel short-circuit current rating (SCCR) and marking requirements, and electrical safety considerations. The new SPD is available for download in its entirety or by section at the Cooper Bussmann Web site.
