Abstract

An electrical port safety guard mechanism in the form of a shutter assembly is positioned between the vertical power bus conductors in an electric motor control center and the electric components contained therein. The shutter assembly allows access to the busbar conductors when the electrical components are inserted within the motor control center and prevents electrical access to the busbar conductors when the electrical components are removed therefrom.
