Abstract: A circuit interrupting safety device (CISD) interrupts the flow of current through a pair of lines extending between a source of power and a load. The CISD includes a column reset assembly functioning as a circuit breaker and a contact actuator, a relay circuit including a solenoid, and a fault detecting circuit packaged in a circuit assembly. The solenoid includes a solenoid pin in an extended state when the CISD is reset and a non-extended state when the CISD is tripped.

Abstract: A cool running ground fault circuit interrupter (GFCI) with radio frequency (RF) noise suppression and a Capacitive Power Supply tbr interrupting the flow of current through a pair of load and neutral lines extending between an input power source and a load is provided. The GFCI includes a pair of switches disposed between the input power source and the load. The switches are actuated by a relay circuit initially powered by a booster circuit and a constant on power supply. A capacitive power supply for cool operation of the GFCI is connected to the load line via a current limiting resistor and provides power to the constant on power supply circuit.

Abstract: A system and method for an LCDI power cord and associated circuits is provided. The system and method include energizing shielded neutral wires and shielded line wires and monitoring the energized shields for surges, e.g., arcing, detected by a Leakage Current Detection Circuit (LCDC) and/or voltage drops, e.g., shield breaks, detected by a Shield Integrity Circuit (SIC).

Abstract: A Testguard circuit with auto-monitoring and end-of-life circuitry is provided. The Testguard circuit interrupts the flow of current through a pair of lines, wherein one of the pair of lines extends between a line input and a line output and the other line extends between a neutral input and a neutral output. The Testguard circuit includes a monitoring module for detecting an end of life condition. The monitoring module includes a simulated ground fault generator for simulating a ground fault; an auto-monitoring logic module; a relay synchronized switch; and an end-of-life switch for disabling the Testguard circuit if certain Testguard component failures are detected.

Abstract: A sealing assembly for mating two sections of an electrical device enclosure is disclosed. The enclosure includes a top and bottom joinable section. The sealing assembly includes a first sealing section disposed on the top joinable section that has both first and second upper projecting lip extensions. The second upper projecting lip extension has a height less than the first upper projecting lip extension and forms a channel therebetween. A second sealing section is disposed on the bottom joinable section, and includes a downward projecting lip extension and channel. The downward projecting lip extension is offset from the first section first upward projecting lip extension when the top and bottom joinable sections are joined. At that point the downward projecting lip extension engages within the channel of the first sealing section, and the second upper projecting lip extension of said first sealing section is engaged within the second sealing section channel.

Abstract: A power cord apparatus for remotely detecting excessive operational parameters in an alternating current (AC) powered machine (e.g., dehumidifiers, air conditioners, refrigerators, and Computer Numerically Controlled (CNC) machines) is provided. The power cord apparatus includes a cooperative remote parametric sensing device (e.g., heat sensing, vibration transducer) in the vicinity of the electrically powered machine.

Abstract: An electric plug includes an end block and a power cord. The end block includes a plurality of first connectors and the power cord includes a plurality of second connectors which correspond to the first connectors and detachably connected thereto. The first connectors and second connectors are electrically conductive. One or more first connectors are connected to the second connectors by press-fitting and are retained therewith by friction. Alternatively, the first connectors may be a terminal screw assembly and the second connectors are wires of the power cord.

Abstract: A push button switch includes a hollowed housing, an electric switching circuit coupled to the hollowed housing and a stack of non-conductive sliders disposed within a narrow recess in the housing. An array of externally accessible push rods extends vertically through the housing and is used to longitudinally displace certain sliders into selective engagement with movable contacts in the electric switching circuit. A plurality of outwardly protruding projections are formed on at least one of the front and rear surfaces of alternating sliders, each projection being generally circular in transverse in cross-section and in the range of approximately 0.001 inches to 0.004 inches in height. The entire surface contact established between adjacent sliders is achieved through the one or more projections, thereby reducing the frictional forces experienced within the stack during slider displacement.

Abstract: A fireguard circuit for a power cable, which comprises a power line, a neutral line and a metal sheath surrounding the power line and the neutral line, includes a switch located in one of the lines. A solenoid sets the switch in either an open position or a closed position. A first silicon controlled rectifier (SCR) causes the solenoid to open the switch upon detecting the presence of an arcing condition between the power line and the metal sheath. A second silicon controlled rectifier (SCR) causes the solenoid to open the switch upon detecting the presence of an arcing condition between the neutral line and the metal sheath. The second SCR is connected in parallel with the first SCR, the anode of the first SCR being connected to the cathode of the second SCR and the cathode of the first SCR being connected to the anode of the second SCR.
