Abstract
A shutter assembly is provided for an electrical system including at least one electrical switching apparatus, such as a circuit breaker, and a plurality of electrical bus members, and a plurality of electrical cable members, and a ground member with a plurality of contacts. Each of the conductors of the circuit breaker is removably coupled to a corresponding primary contact to electrically connect the circuit breaker to the electrical bus members and to electrically connect the circuit breaker to the electrical cable members and to electrically connect the circuit breaker to the ground members. The shutter assembly includes a flexible insulating member movably disposed between the conductors and the primary contacts. The flexible insulating member moves between a first position in which it provides access for the conductors to be coupled to the primary contacts, and a second position in which the flexible insulating member isolates and electrically insulates the bus member conductors from the primary contacts and the cable member conductors ('disconnected') or isolates and electrically insulates the cable member conductors from the primary contacts and the ground member ('withdrawn'). An electrical switching apparatus and an electrical system employing the shutter assembly are also disclosed.
