Abstract: AFCI and/or GFCI units (10) with onboard trip monitoring and/or wiring error monitoring circuit (100) with an opto-isolator (50) and a controller (60) in electrical communication with the opto-isolator (50). The controller (60) monitors the opto-isolator (50) to identify a TRIP or RESET state of the circuit (100) such as one associated with a receptacle and/or a wiring error of the unit (10), e.g., receptacle.

Abstract: The disclosed concept relates generally to current sense techniques and apparatus for arc fault and ground fault receptacles, e.g., circuit interrupters, and, more particularly, to arc fault and ground fault receptacles including a shunt stationary terminal exhibiting both mechanical and electrical functionality. The shunt stationary terminal is composed of a steel or steel alloy and copper or copper alloy composite having a current shunt integrated therein.

Abstract: In-wall dispensing modules, such as room freshener modules, can reside in a housing with a cover that can be opened to access an interior space of the module to, inter alia, replace used containers. The housings are configured to reside inside a wall of a room. The front cover can be a planar cover that is flush, slightly recessed or slightly protrudes from the wall. The housings can be a “custom” housing size and/or may be configured to occupy a single gang box or a compartment of a multi-gang junction box. The modules can include an actuator that can cause a canister to emit scented fluid at desired intervals and/or on-demand. The modules can have a User Interface (UI) wireless and/or wired connection to a whole-house “smart” system.

Abstract: An apparatus for testing an arc fault circuit interrupter includes an AC signal generator circuit configured to be capacitively coupled to an AC power line and to induce an AC signal thereon and a control circuit configured to control the AC signal generator circuit to selectively enable and disable generation of the AC signal responsive to a waveform of an AC power voltage of the AC power line.
