An assembly contains a housing defining an internal space of the assembly, an electronic circuit arranged in the internal space, and a protection strip arranged in the internal space for protecting the electronic circuit against external influences. Accordingly, the protection strip forms a ground conductor that is electrically connected to the housing and to a ground connection of the electronic circuit. Furthermore, a method for producing the assembly is disclosed.

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.

Motor control centers have units or bucket assemblies with a spring-loaded front panel attached to a housing of the unit by a laterally extending metallic shaft that allows the front panel to pivot open about a long axis of the shaft. When closed, the bottom of the front panel slidably receives and is in abutting contact with the shaft which provides an electrical ground.

An enclosure for electrical equipment is provided. The enclosure includes a frame, a first plate, and a first member coupled to the frame and configured to receive the first plate. The first plate is configured to receive a transformer, movable between a first position and a second position, at least partially supported by the first member when the first plate is in the first position, and offset from the first member when the first plate is in the second position.

An electrical feedback barrier is configured to safely interconnect an intrinsically safe power supply to a non-intrinsically safe electrical load device in a hazardous environment. Electrical feedback from the non-intrinsically electrical load device is blocked by the electrical feedback barrier to protect the intrinsically safe power supply from adverse operating conditions. The electrical feedback barrier and the electrical load device are enclosed in an explosion-proof or flameproof enclosure for compliance with electrical equipment safety standards in the hazardous environment.
