摘要:
A wiring system includes a wiring module and a functional module. The wiring module in at least one embodiment includes elongated holes or openings which are configured to engage or lock with prongs on a functional module to create a lockable connection. The wiring module and the functional module form both a physical and an electrical connection. In another embodiment, there is an adapter which is configured to connect the wiring module and the functional module or unit together.

The disclosure relates to an electrical fault interrupter comprising at least one electrical fault sensor which is configured to detect an electrical fault condition, at least one miswiring circuit configured to detect the improper connection to the electrical fault sensor, and at least one circuit interrupter which is configured to open at least one circuit in the presence of an electrical fault or a miswiring condition. In at least one embodiment, one end of the miswiring circuit is coupled to a ground line.

The present invention is directed to current interrupting devices with overcurrent protection. In one embodiment, a ground fault circuit interrupter (GFCI) is disclosed having both ground fault and overcurrent protection. The GFCI has a current detection circuit that includes a switch connected across the load phase terminal and the line neutral terminal of the device. A comparator compares a predefined threshold voltage to a sensed voltage based on a current through the line and load neutral terminals of the device. If the sensed voltage exceeds the predefined threshold, the comparator causes the switch to conduct thereby tripping the device, disconnecting the load from the line terminals and preventing the overcurrent condition from causing damage to the device and/or load.

A lamp holder device for holding a light, the device comprising a body and a plurality of contacts disposed in the body. There is at least one rotatable top rotatably coupled to the body. In addition, there is at least one spring clip disposed in and secured to the body. The spring clip is for selectively securing a light to the spring clip when the light is inserted into the body and further secures the light to the body when the at least one rotatable top is rotated.

A sensor mounting mechanism that includes a base member adapted to be mounted to a structure and a base neck having a first end and a second end where the first end is adapted to be coupled to a sensor with a ball-socket coupling and the second end is coupled to the base member with a rotating coupling. The mounting mechanism provides fine and coarse adjustment means for adjusting the scanning area of the sensor such as an PIR occupancy sensor without the use of a tool. The sensor includes a detachable lens holder for easy replacement of the lens.

A rack mounted component door system according to the present invention is used in conjunction with a conventional equipment rack to secure components in the rack and to provide access to features of the components positioned away from the front side of the rack. The component door system includes two hinge assemblies that can be attached directly to two opposing vertical members of the front side of a conventional rack. The component door system also includes a panel that can be of conventional configuration or tailored for the component door system. The panel is attached to the two hinge assemblies to extend between the two front side vertical members of the rack.

A remote control electrical device which can communicate with a remote control device. The electrical control device is adapted to fit into a housing which fits into a wall mounting. The remote control electrical device can comprise a control circuit disposed in the housing, a transmitter disposed in the housing, a receiver disposed in the housing wherein said transmitter and said receiver are in communication with the control circuit. There is also a support plate having an inside face facing into the housing and an outside face facing away from the housing body. The support plate is coupled to the housing, wherein there is also an antenna disposed on the outside face of the support plate. This antenna does not receive any power-line AC frequencies or DC, instead it is capacitively coupled to the rest of the electrical components and disposed on the outside face of the support plate.

摘要:
A new and novel system for protecting people and property against electrical shock. It includes a number of preferred and other embodiments which have this as their goal, but which represent a number of distinctive and novel approaches to solving prior art problems. By way of example only, and without limiting the scope of this invention, these approaches include novel immersion detecting circuits, broken wire test circuits, electromechanical circuit breaking means including coil/plunger arrangements, and relay circuit breaking mechanisms cooperative with associated circuitry, all of which are able to be incorporated as a system wholly within the load (appliance) and its associated cord set (including a "plug").
