Leviton Manufacturing Co., Inc.

Operating an electrical load controller includes determining a firing angle at which to fire a switching circuit of the electrical load controller and selecting a control signal pulse duration between a fixed duration and a variable duration based on the firing angle and on whether voltage sag is present in an alternating current (AC) waveform, then controlling a supply of AC power to a load based on the selected duration. An electrical load controller and method of operating such is also provided, in which a detection window is selected for detecting zero-crossings (ZC) of an AC waveform, a ZC signal is monitored and a time of a next ZC is ascertained, and a supply of AC power to a load is controlled using the ascertained time.

An electrical panel including a water management system for redirecting water away from any sensitive electrical components and out of the panel. In some embodiments, the electrical panel includes an enclosure including an opening formed in a top surface thereof to enable air to move into and out of the enclosure. The electrical panel further includes a drip lip for directing any water that enters the opening out of the enclosure, the drip lip including a drip tray arranged and configured to receive any water entering through the opening and a channel arranged and configured to receive the water from the drip tray and to direct the water out of the enclosure.

Approaches for controlling supply of power to a load in an environment based on ambient light sensing and dynamic thresholding include, based on an ambient light level in the environment decreasing to a turn-on threshold light level, controlling a switch of an electrical load controller to couple the supply of electrical power to the lighting load, sensing a current ambient light level in the environment after lapse of a predetermined amount of time subsequent to controlling the switch to couple the supply of electrical power to the lighting load, and adjusting a turn-off threshold light level using the current ambient light level.

An electrical device such as, for example, a battery-powered electrical switch is disclosed. The battery-powered wireless switch includes one or more mechanisms arranged and configured to provide simplified access for servicing (e.g., replacing) the batteries located within the wireless switch. In one embodiment, the wireless switch is arranged and configured so that the batteries may be accessed by reconfiguring the wireless switch from a first closed position to a second opened position to access the batteries. Thus arranged, removal of the wireless switch from a wall-box or a surface of a wall is not required, the user may only need to remove the wall-plate in order to reconfigure the wireless switch. In one embodiment, at least a portion of the wireless switch is pivoted from the first position to the second position to provide access to the batteries.

A fiber optic enclosure includes a number of organizational features that simplify fiber routing and installation and that yield improved organization of fiber bundles. For instance, a fiber optic enclosure can comprise an enclosure body, one or more trunk mounting plates mounted inside the enclosure body at an angle relative to a rear wall of the enclosure body, and a subframe below the trunk mounting plates and configured to hold fiber optic trays in a vertical arrangement.

Communication enabled circuit breakers are described. Methods associated with such communication enabled circuit breakers are also described. The communication enabled circuit breakers may include one or more current sensors. The one or more current sensors may be disposed in a clip. The clip may be coupled to a line side phase connection, and the clip may be shielded to attenuate signals.

A fiber optic adapter faceplate comprises port openings and associated structural features designed to tightly hold fiber optic adapters or connectors in a secure manner that prevents sliding or rattling within the port openings. This is achieved in part by a raised button or protrusion formed on a horizontal edge of the port opening, which works together with a curved slot formed through the faceplate near the button to allow the edge of the port to deflect locally when an adapter or connector is inserted, providing a tight fit across a range of varying adapter dimensions.

Wireless communication enabled circuit breakers are described. Methods associated with such wireless communication enabled circuit breakers are also described. The wireless communication enabled circuit breakers may controlled by a remote entity. The remote entity may wirelessly case the wireless communication enabled circuit breakers to trip.

A smart wall-plate system having customizable device controls to initiate automation functions, routines, actions, activities, or control to be performed by a variety of local or remote devices is disclosed. The smart wall-plate system may be connected directly or indirectly to any number and type of local and remote devices as well as various cloud service platforms and home service hubs or assistants. The local and remote devices can include, for example, lighting devices, smart devices, and Internet-of-Things (IoT) devices. The wall-plate system may receive an input from a user. The wall-plate system or another system in communication with the wall-plate system may determine an instruction corresponding to, or triggered by, the received input. The instruction may specify an automated activity to be performed. In response, the wall-plate system or another system may transmit one or more signals to perform the automated activity.

Electrical connectors with integral fault detection are provided. The connectors are adapted to be coupled to AC multi-phase electrical cables, and can include a plurality of phase contacts, a detector, and an indicator. The phase contacts include a first phase contact, a second phase contact, and a third phase contact to receive a first phase, a second phase, and a third phase, respectively, of the electrical cable. The detector is configured to monitor a first temperature associated with the first phase contact, a second temperature associated with the second phase contact, and a third temperature associated with the third phase contact to detect a temperature fault at any of the contacts. The indicator is operatively coupled to the detector and is configured to indicate presence of the temperature fault.
