Abstract: A shutter assembly for a tamper-resistant electrical receptacle includes a shutter, a base clip, and a spring. The shutter is coupled at one end by the spring to the rear side of an individual outlet cover of the electrical receptacle, and two multi-sloped blocking mechanisms of the shutter block access to the live electrical terminals from the hot and neutral slots of the outlet cover when a plug is not inserted into the outlet. The shutter comprises a fulcrum that rests on the base clip, which allows one end of the shutter to interlock with divots formed in the rear side of the outlet cover and the other end of the shutter to interlock with the base clip in order to prevent access to the live electrical terminals when an object is inserted into only one of the hot or neutral slots of the individual outlet cover, or when an object is inserted into the outlet cover at a tilted angle.

Abstract: A thermal protection switch device may include: a power circuit that includes a phase line and a neutral line; a current sensor electrically connected to the phase line to detect the current flow in the phase line; a temperature sensor thermally coupled to the phase line to detect the temperature of the phase line; and another temperature sensor thermally coupled to the neutral line to detect the temperature of the neutral line. The device also includes a trip circuit configured to interrupt the phase line when activated and a controller configured to receive output signals from the above current and temperature sensors. The controller may activate the trip circuit to interrupt the phase line in response to determining that certain conditions have occurred.

Abstract: A shutter assembly is for an electrical receptacle. The electrical receptacle has a base. The shutter assembly includes a first shutter and a second shutter each structured to be coupled to the base and rotate between a FIRST position and a SECOND position, and a slider assembly having a number of slider members each structured to be coupled to the base. The number of slider members includes only one single slider member structured to slide between a THIRD position and a FOURTH position and engage each of the first shutter and the second shutter. Rotation of both of the first shutter and the second shutter from the FIRST position to the SECOND position cooperatively drives the one single slider member from the THIRD position to the FOURTH position in order to provide access through the base.

Abstract: An electrical outlet device includes a connection circuit having neutral, hot and ground terminals that are configured to be connected to a corresponding line of a power source. The device also includes an interface panel with a receptacle configured to receive a load. An indicator interface device is attached to the interface panel. The indicator interface device includes at least three sets of light-emitting diodes (LEDs), and at least three switching circuits that are configured to turn the LED sets on and off. At least one combination of on/off states of the first, second and third LED sets indicates a correct connection or a unique type of error in a connection between the power source and the connection circuit.
