Abstract
A metal-clad compliant grounding/earthing switch device configured for use within conventional switchgear is described. The device is equipped with adequate and compliant insulation of all bus connections, and is configured to close during maintenance outages grounding the live parts of the circuit feed by a particular breaker. The device enables electricians to perform maintenance and repairs in the event of an outage safely, and without the need to manually install a temporary Ground-and-Test Device. An insulated clam shell is present to limit fault propagation from live components until components are confirmed as grounded prior to maintenance of the switchgear.
