Filed:

Jan 15, 2009

Appl. No.:

12/354420

Inventors:

Renjith Mathew - New Hyde Park NY, US
Walter Ancipiuk - Staten Island NY, US
Yun Wu - Bayside NY, US
Alfred J. Lombardi - Syosset NY, US

Assignee:

Leviton Manufacturing Co., Inc. - Melville NY

International Classification:

H01H 3/00

US Classification:

200330, 200 18, 200339

Abstract:

An electrical device controller is provided for controlling power to a load. The controller includes a housing having an open face and a plate having a unitary aperture secured to the housing and disposed over the open face. The controller further includes an electrical power controller component positioned within the housing for coupling to a power source and a load, a first actuator coupled to the electrical component, and an adjacent second actuator coupled to the electrical component. The first actuator has a movable user operable portion that is user accessible via the unitary aperture for controlling power ON/OFF to the load. The second actuator has a movable user operable portion that is user accessible via the unitary aperture for adjusting magnitude of power delivered to the load. The movement and position of the respective user operable portions of the first and second actuators are mutually independent.

International Classification:

G01R 31/02
H02H 3/33
G01R 35/00
G01R 31/327

Abstract:

An apparatus includes an interruption circuit in a power delivery path, and a fault detection circuit configured to provide a fault signal to selectively cause the interruption circuit to interrupt power delivery, wherein the fault detection circuit includes a fault detection integrated circuit and a sensing coil configured to sense a differential current between a phase conductive path and a neutral conductive path in the power delivery path. A processor is configured to selectively control a fault simulation circuit to simulate a fault in the power delivery path, detect a response of the fault detection circuit to the simulated fault, and determine if the response of the fault detection circuit is an expected response. The processor provides an override signal to the interruption circuit to prevent the interruption circuit from receiving a fault signal from the fault detection circuit during, and for a predetermined time after, the simulated fault.

Assignee:

Leviton Manufacturing Co., Inc. - Melville NY

International Classification:

H01H 23/02
G05F 1/455
G08B 5/36

Abstract:

An electrical load controller includes an electrical switching device and an actuator assembly having at least one user actuator for use in turning power on and off to the load and for use in adjustably controlling the level of power to the load. A frame attached to the actuator includes an integrally formed backlightable indicator region having an outer continuous solid surface. Light from an illumination assembly related to the level of power to the load is directable onto a portion of an inner surface of the backlightable indicator region, transmittable through the backlightable region from the inner surface to the outer surface, emittable from a portion of the outer surface, and observable by the user.
