This document discusses switch-rated plugs and receptacles that provide safety benefits over standard plugs. It notes safety issues that can occur when removing standard plugs while energized, including arc flash events. Switch-rated plugs and receptacles are designed to safely make and break connections under full load. They allow for easy lockout/tagout and simplify compliance with NFPA 70E standards by eliminating the need for personal protective equipment in many applications. The document provides information on UL/CSA performance testing and approval standards. It discusses the design features and materials used in switch-rated plugs and receptacles that enable safe operation. Examples of common industrial applications and industries that use switch-rated plugs are also given.
