A wireless-controlled smart plug device and methods of use and operation, using a solid state switch to provide electrical power from an outlet to a load, and provide protection against overload, short circuit, ground, arc, or voltage surge faults. The switch includes a bidirectional semiconductor switch with two back-to-back connected transistors, such as silicon power MOSFETs, silicon insulated-gate bipolar transistors (IGBTs), silicon carbide (SiC) transistors, or gallium nitride (GaN) transistors, each configured to control the current flow from the electrical receptacle to the external electrical load.

A universal ground fault circuit interrupter (GFCI) device for interrupting the flow of current through a pair of lines extending between a source of power and a load. The GFCI device is easily adaptable to fit into a plurality of enclosure types and includes a top surface having a stationary assembly. The stationary assembly includes a load section a GFCI circuit section, and a power source section, wherein the components of the device are arranged to minimize space, maintain arcing and dielectric prevention distances, and allow for peripheral load and source connections facilitating easy adaptability into a variety of GFCI enclosures.

The present invention is directed to switch device disposed in a housing with a back body portion, the device includes a switch actuator having a user-accessible surface, the user accessible surface includes an indicator element and an interior channel optically coupled to the indicator element. A light emitting portion is disposed within the interior channel and optically coupled to the indicator element so that the interior channel moves relative to the light emitting portion when the switch actuator moves between the first actuator position and the second actuator position. The light emitting portion is optically coupled to the indicator element when the interior channel moves relative to the lighting portion. A modular lighting assembly is removably coupled to the back body portion at a fixed position so that a light emitting portion of the modular lighting assembly is disposed within the interior channel and optically coupled to the indicator element.

A device may include a housing including a face plate. A device may include a plurality of sensing cores each configured to receive a current flow through a center cavity, the current flow defining a current flow direction through the center cavity, wherein the current flow direction is parallel to the face plate.

An arc flash protection system includes: an arc flash detection module electrically connected directly to a cord coupled to an electrical load and electrically connected to a ground fault circuit interrupt (GFCI) outlet, the arc flash detection module configured to: measure at least one of voltage and current of the cord; and based on the at least one of the voltage and the current of the cord, determine and indicate whether an arc flash condition is present; and a GFCI triggering module configured to, in response to the arc flash detection module indicating that an arc flash condition is present, output a predetermined current to a ground conductor of the cord.

A protective hood for outdoor electrical outlets or receptacles has a top surface, two side panels, and an angled bottom surface having an aperture. In one variant of the protective hood, the aperture in is configured to receive power cords for connection to an electrical outlet over which the protective hood has been mounted, such as an existing electrical outlet installed on a building wall or a power pedestal. In another variant of the protective hood, the aperture in the angled bottom surface is configured to allow an electrical outlet to be installed directly therein, but with the protective hood still being mountable over an electrical outlet on a building wall or power pedestal instead of having an electrical outlet installed in the aperture.

A rack BMS detects a ground fault through a circuit embedded therein, and as a master BMS is configured to disconnect all the connections between battery racks and a grid in the case in which the rack BMS detects the ground fault, no more current flows through chassis, thereby protecting the battery racks and ensuring safety of a person using the battery racks.

An electrical switching apparatus includes a housing member, a printed circuit board assembly having a board including a first side and a second side facing away from the first side, and a barrier member coupled to each of the housing member and the first side of the board. The barrier member substantially encapsulates the first side of the board.

A bag for transporting tools and building supplies includes a body, a first spool, a second spool, an electrical plug coupled to a first electrical cord, and an electrical connector coupled to a second electrical cord and defining an electrical outlet. The body includes a side panel coupled to and extending from a base member. The base member and the side panel cooperate to define an internal volume. The first spool and the second spool are each rotatable relative to the body and positioned within the internal volume. The first and second electrical cords wrap around the first and second spools, respectively, and extend outside of the body. The electrical plug is electrically coupled to the electrical connector. The electrical plug is interfaces with an external power source such that the electrical outlet receives electrical power from the external power source.

A power pedestal for electrical outlets is mountable to a mounting surface by means of a pedestal base incorporating stress-relief means that will allow the pedestal to break away either partially or completely from the base in response to an external force acting on the pedestal so as to induce stresses in the pedestal base exceeding a predetermined magnitude. The pedestal base may have one or more vertical elements to which the pedestal can be connected. Ground attachment points may be provided in one or more of the vertical elements, for protection against loss of pedestal grounding in the event of impact damage to the pedestal. The power pedestal may include protective apparatus comprising an angled hood having an angled top surface and an angled bottom surface having an aperture for mounting an electrical outlet.
