Abstract: A wiring device assembly with one or more electrical contacts having respective contact stabilizing assemblies which are operable to rigidly hold the electrical contacts in a device housing. The contact stabilizing assemblies prevent the contacts from becoming displaced within the housing under vibrational, rotational and other stresses. The contact stabilizing assemblies are connected to the electrical contacts and fit in housing channels specifically shaped to accommodate the stabilizing assemblies.

Abstract: A self test (ST) ground fault circuit interrupter (GFCI) provides improved end of life (EOL) detection by rejecting false EOL information. A processing device receives fault detection signals indicating when faults are detected, and input signals indicating when contacts used to interrupt power to a load are closed. The processing device rejects the fault detection signals when they fail to meet a selected condition and the contacts are closed, and declares end of life (EOL) when the selected condition is met. The fault detection signals can correspond to pulses at an output of a gated device between the processing device and a GFCI chip, and the selected condition can be a selected integer number of pulses.

Abstract: A pipeline buoyancy control assembly is operable to simultaneously retain a plurality of pipelines against buoyancy forces. Respective ends of two retaining straps corresponding to two respective pipelines engage a tie-down member of a single control assembly. The retaining straps are placed over the respective pipelines and other ends of the retaining straps are attached to additional control assemblies. Further, stresses exerted on the retaining straps when the pipelines are subjected buoyancy forces are minimized by the unique structure of the tie-down member and the manner by which the retaining straps attached thereto.

Abstract: A lighting device including a test device for testing the proper operation of a primary and a secondary power supply alternatively providing electrical power to the light. The test device is attached to a bracket using a single fastener such as a nut and the bracket is attached to a receptacle for the light using a different single fastener, such as a pop-rivet or screw.

Abstract: An outlet box assembly for installation within a wood, tile or carpeted floor, or any other type of flooring, includes a housing for accommodating an electrical power and/or data receptacle as well as the wiring connected to the receptacle and an adjustment mechanism attached to an outer surface of the housing for adjusting the receptacle downwardly to a recessed position a predetermined distance below the flooring material. The adjustment mechanism further includes an attachment mechanism for attaching the outlet box assembly to either the top or side surface of the floor. A cover plate is provided with a tapered recessed box and an access door for easy access to the recessed receptacle.

Abstract: An electrical device box which houses both high and low power devices, such as power and data receptacles, is disclosed. A detachable divider is inserted into the device box to separate the interior of the box into two separate chambers, one for housing the high power device and its corresponding wiring and a second chamber for housing the low power device ant its wiring. The divider is shaped such that one of the chambers has a greater volume than the other chamber and its orientation within the box can be reversed to selectively determine which of the two chambers has the greater volume. Additionally, the electrical box and divider are sizable to accommodate single-gang, double-gang, or larger, configurations.

Abstract: An in-floor electrical floor-box assembly includes a rectangular or nearly square metallic housing and a non-metallic riser with integral flange assembly having a rectangular flange that mates with the rectangular housing and an integral cylindrical riser for providing access to the electrical components through a round cover and finish flange. A low-voltage divider assembly separates cables carrying different voltages within the riser to reduce interference between the cables and any one of a variety of sub-plates having different configurations for accommodating a variety of multi-service or single service electrical functionality can be incorporated with the box.

Abstract: A ground fault circuit interrupting device detects an end-of-life condition. A ground fault detecting circuit detects a fault condition and controllably operates a switching device to energize a circuit interrupting device. An end-of-life detecting circuit detects a failure of the circuit interrupting device to open after detection of the fault condition, and activates a secondary circuit to energize the circuit interrupting device.

Abstract: An outlet box assembly for installation within a concrete floor, or any other type of poured flooring, includes a housing for accommodating a receptacle assembly with an electrical power and/or data receptacle as well as the wiring connected to the receptacle and the receptacle assembly has a self adjusting attachment ring that accommodates the tapered inner walls of the housing and the receptacle assembly accommodates either a standard electrical outlet or a multimedia outlet with connections for power and one or more of voice data and audio video data.

Abstract: An electrical floor box for providing multiple services such as electrical service and communication service has a housing formed from a top section, a bottom section, and a middle section connecting the top and bottom section. The housing is covered by a cover that rests in a cover flange. The cover flange has a gutter for collecting any liquids that seep into the housing. A removable power panel rests in the interior of the housing and provides electrical receptacles. An accessory box for providing additional services such as compressed air and water can be attached to electrical floor box.

Abstract: A circuit interrupting device has a circuit interrupter with a stationary contact and a moveable contact. The movable contact is movable relative to the stationary contact between a closed position that allows current to pass through the circuit interrupter and an open position separating the contacts and preventing current from passing through the circuit interrupter. The movable contact is controlled by a solenoid assembly. The movable contact is connected to a plunger of the solenoid assembly by a turnbuckle and weld break assembly. The turnbuckle and weld break assembly permits adjusting the contact wipe distance and generates a hammer force to break any welds between the contacts of the vacuum interrupter.
