    Abstract: Arc fault protection for a digital electricity distribution system that provides power to a device. The system includes an arc fault circuit interrupter (“AFCI”) and a controller. The controller is connected to the AFCI. The controller is operable to control the AFCI to disable power to the device. The controller includes a processor and a memory. The controller is configured to transmit a digital electricity energy packet through the AFCI to the device, measure an amount of error associated with the digital electricity energy packet, evaluate the amount of error associated with the digital electricity energy packet, determine whether an arc fault condition is present based on the evaluation of the amount of error associated with the digital electricity energy packet, and control the AFCI to disable power to the device when the arc fault condition is determined to be present.

    Abstract: This application discusses components that can be used to prevent flame or hot gas transmission from the inside of a luminaire enclosure to the outside of a luminaire enclosure due to an internal explosion, thereby yielding an explosion encapsulating luminaire enclosure. Accordingly, the components and assemblies described herein can be safely integrated with systems that operate in the presence explosive gas.

    Abstract: An inrush current protection circuit for a solid state lighting fixture is provided. The inrush current protection circuit includes one or more current limiting devices and one or more switching devices coupled in parallel with the one or more current limiting devices. The one or more switching devices are configured in a first state when the solid state lighting fixture draws an inrush current from a power source. The inrush current is provided to the one or more current limiting devices when the one or more switching devices are in the first state. The one or more switching devices are configured in a second state when the solid state lighting fixture draws a steady-state current from the power source. The steady-state current bypasses the one or more current limiting devices when the one or more switching devices are in the second state.

    Abstract: A breakaway electrical connector is provided. The connector includes a first side that is connectable to a first conductor and a second side that is connectable to a second conductor. The first side has a magnetic assembly and a first plurality of contacts, while the second side has a strike plate and a second plurality of contacts. The magnetic assembly provides a magnetic connection force with respect to the strike plate to maintain the first and second sides in a connected state with the first and second plurality of contacts electrically coupled to one another.

    Abstract: Methods, systems, devices, and products for use in a pole support system. Apparatus include a hinge joint comprising: a base having an insertion end with a longitudinal slot and with a fulcrum protrusion on an inner surface; a cup having a receiving end selectively receiving the insertion end of the base; a securing assembly configured to selectively release the cup from the base, the securing assembly comprising a rotatable shaft that translates along the longitudinal slot between at least i) a lower relative position corresponding to an engaged state in which the insertion end is received by the receiving end, and ii) an upper relative position corresponding to a released state in which the insertion end is free of the receiving end; the shaft having a cam projection positioned to contact against the fulcrum protrusion and displace the shaft toward the upper relative position when the shaft is rotated.

    Abstract: A circuit interrupting device including a phase conductor, a neutral conductor, an interrupter configured to disconnect the phase conductor and the neutral conductor from a load, and a sensor configured to generate a signal indicative of current flowing through the phase conductor and the neutral conductor. The circuit interrupting device further includes a microcontroller that includes an electronic processor and is electrically connected to the first sensor and the interrupter. The microcontroller is configured to generate a reference signal, receive a first signal from the sensor, determine whether a difference between a voltage of the first signal and a voltage of the reference signal exceeds a threshold, determine whether the microcontroller has performed a ground fault self-test, and activate the interrupter when the difference exceeds the threshold and the microcontroller has not performed the ground fault self-test.
