A dimmer includes a sole intensity actuator structured to be used for at least one of: adjusting light intensity based on a first user input during normal operation; or entering configuration mode based on a second user input and adjusting an end trim value based on a third user input; a sole intensity potentiometer coupled to the sole intensity actuator and comprising a variable resistor, the sole intensity potentiometer structured to measure an input voltage based on variable resistance, and a controller coupled to the sole intensity potentiometer and a driver circuit coupled to a bidirectional switching device, the controller structured to control dimmer operation, comprising receiving an input voltage signal and transmitting a dimming signal to the driver circuit, the dimming signal based at least in part on the signal.

Dimmers having capabilities to adjust end trim values

A system for controlling delivery of power to a load includes a master control unit (MCU) and a synchronous solid-state relay. The MCU causes the relay to close when the voltage delivered to the relay is at a zero crossing state. The MCU causes the relay to open at either (a) the moment when the voltage delivered to the relay is at a zero crossing state, or (b) the moment that the current delivered to the relay is both over a threshold level and at a zero crossing state.

Switch with current and voltage collection

AFCI and/or GFCI units () with onboard trip monitoring and/or wiring error monitoring circuit () with an opto-isolator () and a controller () in electrical communication with the opto-isolator (). The controller () monitors the opto-isolator () to identify a TRIP or RESET state of the circuit () such as one associated with a receptacle and/or a wiring error of the unit (), e.g., receptacle.

Electrical units with onboard electronic monitoring and related methods

A system for delivering power to a load includes a master control unit (MCU) communicatively connected to a wireless network. A remote control circuit is electrically connected to the MCU. The remote control unit delivers a signal of a first voltage to the MCU when the remote control unit is not receiving a command signal from a remote controller, and deliver a signal of a second voltage to the MCU when the remote control unit is receiving a command signal from the remote controller. A relay unit is electrically connected to the load and to an output of the MCU. The MCU is programmed to selectively power the load by selectively passing control signals to the relay unit in response to commands received from the wireless network. When no signals are received from the wireless network, the remote control circuit may control the load, either directly or via the MCU.

A light pipe is for an EV charging handle. The EV charging handle includes a housing having a thru hole, and a light source coupled to the housing. The light pipe includes a body structured to be coupled to the light source in order to transmit light from the light source through the thru hole of the housing, the body having a first side portion having a first interior surface having a first surface roughness, and a second side portion extending from the first side portion, the second side portion having a second interior surface having a second surface roughness greater than the first surface roughness in order to increase a visibility range with which the light is transmitted through the thru hole of the housing.
