Abstract: An electrical receptacle assembly comprising a housing defined by a first compartment and a second compartment removably securable to each other by means of fasteners. The first compartment has an operative sidewall defining a first opening and an operative base defining a second opening, wherein the first opening has hourly graduations with a corresponding first securing formation for each graduation on the operative front face of the sidewall facing the outside of the first compartment. A sleeve formation extends from the sidewall defining the first opening and surrounding the graduation. A terminal block configured to be securely fitted within the first opening. The terminal block has second securing formations complementary to the first securing formations on the first opening to enable the terminal block to be rotatably mounted in the first opening corresponding to a desired voltage rating.

Abstract: A connector part to be connected to an associated mating connector part includes a housing having a plug-in portion that can be plugged into a mating plug-in portion of the mating connector part in an insertion direction and is connected to the mating plug-in portion when in a connection position. At least one electrical contact element is arranged on the plug-in portion, the at least one electrical contact element electrically contacting the mating connector part when in the connection position. A locking element is moveably arranged on the housing, the locking element interlocking the connector part with the mating connector part when in the connection position. The connector part includes a switch device with a switch portion that can be actuated when the locking element is moved to control a current flowing over the at least one contact element.

Abstract: A connector for connecting power or control systems infrastructure such as for example subsea infrastructure, said connector comprises a male component and a female component, the male and female components comprising cooperating mating surfaces and means for locking the male and female components together, the locking means being retractably mounted within one of the male or female components but extendible from that component into the other of the male or female components to lock the two components together against axial and rotational movement while providing a snag free release when the locking means is in the retracted position. The means for locking includes pivotal levers with free ends that are to enter recesses of the male component and that are to be held in locking position by a moveable control coupler. An electrical coupler located within the female component is to be raised to engage a corresponding coupler on the locked in position male component.

Abstract: A transfer switch mountable in a standard electrical panel connects either a utility supply or an auxiliary supply to an electrical system. An internal mechanical interlock prevents both the utility supply and the auxiliary supply from simultaneously being connected to the system. The transfer switch may utilize either a rocker-style or a blade style switch. A light-emitting diode provides an indication of whether the utility supply is connected to and a voltage is present at the utility supply terminal. A power meter provides an indication of the magnitude of power drawn from the auxiliary supply when the auxiliary supply is connected to the load.

Abstract: An apparatus is disclosed for mutual interlocking of two switches, in particular circuit breakers. In at least one embodiment, the apparatus includes two plungers which each engage in one of the two switches and can be moved in the plunger longitudinal direction, wherein, when one switch is being switched on, the plunger which engages in this switch is moved by pivoting of a control disk from its nil-point position to its opening position. In at least one embodiment, the apparatus includes a blocking device which blocks pivoting of the other control disk by moving the plunger to its opening position. In order to achieve a maintenance-free apparatus, in at least one embodiment it is proposed that at least one blocking element of the blocking device is moved by the plunger when this plunger is being moved to its opening position, such that pivoting of the other control disk with respect to the other plunger, which is located in the nil-point position, is blocked.

Abstract: A mechanical interlock of a lever operated receptacle with a shaft operated switch is disclosed and provides mechanically interlocked electrical service to cord-connected equipment such as wheeled gantries, vehicles docked at port terminals, heavy manufacturing, and mining equipment. The power transmission safety system locks a plug into a receptacle until a main power switch has been disengaged and a grounding switch has been engaged. Only if the receptacle is switched off and grounded will the receptacle allow a plug to be inserted. The power transmission safety system is mechanically prohibited from being engaged or ungrounded until a plug has been inserted into the receptacle and locked into place. To again unlock and remove the plug from the receptacle, the power transmission safety system must be deactivated and grounded.
