Abstract: In accordance with one embodiment of the present invention a multi-chamber GFCI housing apparatus is provided. The multi-chamber GFCI housing includes a printed circuit board (PCB) chamber and an isolated cable chamber; each chamber is independently accessible and water resistant. In addition, the relative volumes, of each independent chamber permit sufficient housing volume to allow for sufficient spacing between electrical GFCI components and electrical PCB traces to prevent the risk of arcing between the components while also adhering to constrained dimensions according to electrical codes and standards.

Abstract: A programmable arc fault circuit interrupter (AFCI) is provided. The programmable AFCI includes a dual resistive shunt array for developing inputs to an analog front end which in turn develops trigger quantities for input to a programmable processor. The programmable processor determines if the trigger quantities, singularly, or in the aggregate, exceed predetermined thresholds. Determining the predetermined thresholds are exceeded the processor issues a trigger command to momentarily energize a delatching coil, thus removing AC mains power from a load.

Abstract: A water and flame barrier button assembly is incorporated into an electrical enclosure such as a GFCI housing to provide water and flame resistant set and reset buttons. The buttons are contained within flexible sealing frames that allow one end of the buttons to extend through the top portion of the GFCI housing while the opposite end of the button is exposed within the base portion of the sealing frame. The base portion of the sealing frame attaches to the interior of the housing with the exposed button end positioned inward of the sealing frame base. The base of the sealing frame contacts the GFCI circuit board while providing a rebound force to return either the set or reset button exposed end from a position depressed and in contact with the circuit board to a position not in contact with the circuit board and returning inward of the sealing frame base.

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: 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 latching device, a relay circuit including a solenoid, and a fault detecting circuit packaged in a circuit assembly.

Abstract: An appliance leakage current interrupter (ALCI) for interrupting the flow of current through a pair of lines extending between a source of power and a load. The appliance leakage current interrupter having a housing integrating components that would normally be positioned on an ALCI circuit board. The ALCI having a prong assembly for supplying power from a source of power to the remainder of the ALCI, the prong assembly having first and second contact prongs which are in a first embodiment integrated into an ALCI circuit and in a second embodiment integrated into the housing assembly.

Abstract: A Ground Fault Circuit Interrupter (GFCI) interrupts the flow of current through a pair of lines extending between a source of power and a load. The GFCI includes a circuit breaker, a relay circuit including a solenoid, a latch circuit, and a fault detecting circuit packaged in a circuit assembly. The GFCI is adaptable for a quick connect of a load input cord by a user, allowing for various configurations of cords to be utilized on site, the cord easily connected from the device being protected to the GFCI at the point of use. The GFCI circuit assembly includes a load input section having cable securement jaws for connection of the load input cable terminal ends.

Abstract: A leakage current detection and interruption (LCDI) device, for use as a safety device for a cable connecting, a power source with a load. The LCDI having a safety circuit that senses the presence of an arcing condition between one of the conducting lines and a metal sheath, and in response thereto, opens at least one of the conducting lines between the power supply and the load. The structure of the LCDI circuit card assembly incorporates a load input cavity having fire retardant materials surrounding the load input terminals, and further includes a contact actuator which encases the switch or contact arm at the source input section of the LCDI.
