A solid state circuit breaker has both solid state electronics and a physical switch. The solid state circuit breaker facilitates power measuring for end loads connected to a panel board circuit, e.g. receptacles, lighting, etc., over current protection, and disconnection all within one device. The solid state circuit breaker can be used at 100% of its rated capacity as opposed to 80% code-mandated limitation for thermal magnetic circuit breakers. The solid state circuit breaker also can provide power/current data (real-time) without the need of an additional device. The solid state circuit breaker further facilitates electronic, i.e. remote, opening, closing, and current limiting for demand response or load shedding.

A load center assembly is provided. The load center assembly comprises a frame, an electrical panel assembly, and a plurality of electrical wire harnesses. The frame includes a first side and a second side. The first side and the second side are substantially parallel and connected by a plurality of cross members. The electrical panel assembly is connected to the first side and the second side. The electrical panel assembly includes a plurality of breakers. The plurality of electrical wires harnesses is connected to the frame. Each of the plurality of electrical wire harnesses includes a plurality of wires. A first end of each wire of the plurality of wires is routed into the electrical panel assembly and is terminated in a corresponding breaker. The load center assembly is configured to be disposed in a wall frame.

A wireless light switch harvests energy for ambient environment/space conditions and uses the harvested energy to energize low-power electronics. An exemplary application is for wireless control (ON/OFF or dimming) of light fixtures. The energy harvesting circuitry transduces ambient light to electricity and uses this energy to charge an energy storage device as well as power a wireless transmitter which can be triggered based on user interaction with an ON/OFF or Dim+/Dim&#x2212; element. The wireless light switch with energy harvesting circuitry is paired with a wireless receiver circuit which can be connected to a light fixture that is to be controlled by the wireless light switch.

Wireless light switch with energy management control

A switch has a first input to couple to an AC electrical power source, a second input to couple to a DC electrical power source, and an output to couple to an electrical power load. A control module transmits a signal to the electrical power load to determine whether the electrical power load uses AC electrical power or DC electrical power, and receives in response thereto an indication that the electrical power load uses one of AC electrical power and DC electrical power. The control module then transmits a signal to the switch to configure the switch to receive electrical power from one of the AC electrical power source and the DC electrical power source and transmit the received electrical power to the electrical power load, responsive to the received indication.

An electrical power input adapter coupled to a direct current (DC) bus in a power distribution system receives either an alternating current (AC) power signal or a DC power signal at a first voltage level to transmit to the DC bus. An electrical converter receives and converts the received signal to a DC power signal at a second fixed voltage. A second interface includes a current limiter to receive and limit an amperage of the DC power signal at the second voltage. A programmable switch coupled to the current limiter receives the DC power signal at the second voltage and at the limited amperage and transmits the DC power signal at the second voltage and at the limited amperage. A controller coupled to the programmable switch controls when, within a period of time, the programmable switch is to transmit the DC power signal at the second voltage and at the limited amperage. An integrator receives the DC power signal at the second voltage and at the limited amperage when transmitted within the period of time and converts it to a DC power signal at the second voltage and at a second amperage that is proportional to the limited amperage integrated over the period of time.
