A solid dielectric deadfront electrical switch assembly having a switch contact assembly. The switch contact assembly can include an upper insulative diaphragm, a male pin contact having an insulating tip and an isolating sleeve, a primary contact, a lower insulative diaphragm, and a female socket contact. The upper insulative diaphragm, isolating sleeve, and insulating tip can assist in electrically isolating the male contact pin when the electrical switch assembly is in an open condition. Further, the upper insulative diaphragm can be separated from the female socket contact, and/or a female-contact insulating sleeve, by a gap chamber that utilizes air as an insulator. The lower insulative diaphragm can be configured to engage a drive rod that is used to axially displace the male pin contact between open and closed positions in a manner that may prevent arcing between the switch contact assembly and a base plate of a switchgear.

The invention relates to the novel ornamental and utilitarian features of a module/adapter (e.g. male-to-male power adapter) for safety connecting the output interface of a backup power source (such as the outlet of a generator) with an electric circuit (such as a female duplex power outlet of a typical home). Such connection requires a male-to-male adapter which would be unsafe without the disclosed safety features.

The present invention is directed to an electrical wiring system having a frame assembly that includes a frame opening at a central portion thereof. The frame opening provides access to the interior of the device wall box. At least one electrical wiring device is configured to snap into the frame opening such that the interior of the device wall box is completely enclosed by the frame assembly and the at least one electrical wiring device such that access to wiring disposed within the device wall box is substantially prevented. The at least one electrical wiring device includes at least one user-interface. An aesthetic overlay may be coupled to the frame assembly. The aesthetic overlay includes an overlay opening configured to accommodate the at least one user-interface such that the at least one user-interface is accessible to a user.

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.

An electrical receptacle contains a plug outlet that has a pair of contacts for electrical connection to respective hot and neutral power lines. A controlled switch, such as a TRIAC, is connected in series relationship between the outlet contact and the hot power line. Sensors in the receptacle outputs signals to a processor having an output coupled to the control terminal of the controlled switch. The processor outputs an activation signal or a deactivation signal to the controlled switch in response to received sensor signals that are indicative of conditions relative to the first and second contacts.

A leakage current protection device (such as a power plug) for an electrical appliance includes a shell and a trip assembly inside the shell. The shell includes an upper cover and a base cover joined together, and either the upper cover or the base cover includes a first cover and a removable second cover. The removable second cover spatially corresponds to a tail portion of the trip assembly; when it is removed, the tail portion is exposed to allow a power cord to be connected to the leakage current protection device. By using a removable second cover, the cord can be conveniently assembled with the device when the device is installed on the electrical appliance, allowing the to be shipped without the cord. This can reduce the packed size of the device for easier shipping and storage, as well as lowering cost. It also makes the device more versatile.

A wiring device including one or more line contact arms electrically connected to a line terminal. Each line contact arm has an upper line contact located on a bent portion of the line contact arm, and a lower line contact located on a substantially straight portion of the line contact arm. The wiring device further includes one or more load contact arms electrically connected to a load terminal. Each load contact arm has a load contact located on a bent portion of the load contact arm.

The present disclosure provides a connector protection method in which the connector is used to connect a first device and a second device, and the method includes, a first detection unit of the first device detects a first parameter of the first device; a first controller of the first device obtains a second parameter from the second device through the communication line in the connector; and the first controller determines whether the connector is faulty based on the first parameter and the second parameter.

A leakage current protection device includes an electrical and mechanical assembly which includes: a circuit board; moving contact plates; an auxiliary switch; a reset shaft, having a hook in its lower portion, a bottom end of the reset shaft being set against one end of a reset spring, another end of the reset spring being set against the base; a disconnect mechanism, having a hook at its upper portion to engage with the hook of the reset shaft in a vertical direction; a trip coil and a trip plunger disposed on a side of the disconnect mechanism, where the disconnect mechanism is driven by the trip plunger to move horizontally. The disconnect mechanism further includes a pushing end that controls the auxiliary switch and lifting levers that control the moving contact plates.
