Prefabricated electrical modules and system along with fabrication and construction methods are provided. The prefabricated electrical system includes multiple framed, prefabricated electrical modules of one or more types. The prefabricated electrical module disclosed may comprise one or more of a main service electrical module, a low-voltage module, a switch component module, and a receptacle component module. The casing of the interior components of the modules is weatherproofed and/or weatherized. Each of the modules includes a module exterior frame that accommodates the specialized elements of that particular module. Methods for fabrication of the modules are disclosed. Construction methods for installing the assemblies are also disclosed.

Various embodiments of the apparatus and/or methods are described for routing power to a wall-mounted appliance, particularly for routing electrical wiring and audio/video cabling up through a wall to power and communicate with a wall-mounted presentation device. The apparatus and systems include input and output enclosures with wiring therebetween and mechanisms for mounting the input and output enclosures adjacent to pre-cut wall openings. There exists at least one electrical input connector, disposed within the input enclosure, configured to electrically couple with a power source, and at least one electrical output connector, disposed within the output enclosure, configured to electrically couple with a wall-mounted appliance.

As described herein, a wall box installation tool may include a template body, one or more hollow pegs, a guide ring, and/or one or more template cards. The template cards may be configured to be installed on a front surface of the template body. A template card may define a plurality of holes therethrough. The guide ring may be configured to be installed within a pre-drilled hole in a wall. Each template card may be associated with a respective electrical device configuration. A subset of bores extending through the hollow pegs may be accessible via the template card when the template card is installed on the front surface of the template body. The wall box installation tool may include one or more fasteners that are configured to install a template card onto the front surface of the template body.

An on-board control apparatus includes: a controller connected to a controlled device mounted in a vehicle via a signal line and configured to control the operation of the corresponding controlled device; and a power source box connected to a power source mounted in the vehicle via a power line, that is connected to the controlled device mounted in the vehicle via a power line, and configured to switch between supply and non-supply of power from the power source to the controlled device, wherein the power source box includes; a switch disposed in a power supply path from the power source to the controlled device; a reception unit configured to receive an input of the switching command; and a switching control unit configured to switch between conduction and interruption of the switch in response to the switching command received by the reception unit.

A power supply system includes an electric storage device, a connecting terminal area, a main energization line, a sub-energization line, a first energization switching unit for switching between an energized state and a non-energized state of an energization line of the main energization line connecting the electric storage device and a loading apparatus, a second energization switching unit for switching between an energized state and a non-energized state of an energization line of the main energization line connecting a branched part and the connecting terminal area, a third energization switching unit for switching between an energized state and a non-energized state of an energization line of the main energization line connecting the second energization switching unit and the connecting terminal area, and a control device that detects switching states of the first, second and third energization switching units and that controls their switching operations.

A bracket assembly is disclosed to secure a cable bundle to a ladder rung. The bracket assembly includes a metal bracket and protective grommets. The metal bracket has a first member, side walls and second members. The first member of the metal bracket is parallel to the second members of the metal bracket. The protective grommets are secured to the metal bracket. The protective grommets have a base member, sleeves extending from the base member, a side member and a bottom member. The assembled metal bracket and protective grommets receive the ladder rung and the sleeves of the protective grommets wrap around the cable bundle positioned on the ladder rung to secure the cable bundle.

Electric vehicles such as scooters can have a first operating mode in which energy is supplied by a single electrical energy storage device and a second operating mode in which energy is supplied by multiple electrical energy storage devices. A circuit element can be included in the circuit connecting the electrical energy storage devices to a prime mover such as a traction motor. The circuit element has a first, electrically conductive, state that couples only the single electrical energy storage device to a traction motor and a second, electrically non-conductive, state that couples the multiple electrical energy storage devices to the prime mover. The transition of the circuit element from the first state to the second state can occur by irreversibly fracturing the circuit element upon installation of multiple electrical energy storage devices or by a controller transitioning the circuit element from the first state to the second state.

An apparatus includes an adapter having a charging unit defining a space configured to receive a wireless headset. The charging unit includes transmit circuitry configured to wirelessly transmit power to the wireless headset when the wireless headset is inserted into the space of the charging unit. At least a portion of the adapter is configured to be inserted into an auxiliary or accessory power socket of a vehicle. The power socket could represent a cigarette lighter holster.
