摘要:
A circuit breaker panelboard modular assembly employs a plurality of interdependent molded plastic and metal parts to multifunctionally adapt breakers of different ratings for electrical connection within the panelboard enclosure. Anti-turn connector connects the line strap terminal. Captive bolts or plug-in connections are employed to attach the breakers to the power bus. A novel concealed hinge construction is used to connect the panelboard door to the panelboard housing and the breakers are individually identified within the housing by extruded plastic circuit markers.

A circuit breaker assembly includes a housing, a trip mechanism, a vent channel, and a chamber. The trip mechanism is positioned within the housing can causes a movable contact to separate from a second contact in response to detection by the circuit breaker assembly of an electrical fault. The vent channel is formed in the housing and positioned to exhaust gas and debris produced as the movable contact separates from the second contact during the electrical fault to an aperture in the housing. The chamber has a chamber housing coupled to the housing adjacent the aperture such that the chamber receives the gas and debris exiting the aperture.

A headless wire binding screw for use in a circuit breaker contains a slotted drive in combination with a Robertson drive. The slotted drive is for use with a slotted-type driver (such as a slotted screwdriver) and the Robertson drive is for use with a Robertson-type driver (such as a Robertson screwdriver). The screw has a body with a diameter of constant size along the entire length of the body. The screw also has an external thread that is formed along the entire length of the body.

An electrical device to be used with an electrical load which is repetitively cycled on and off. The device includes a controllable switch for connecting the load to, and disconnecting the load from, the electrical power source; a device for detecting when the load is drawing power, and a memory module connected to the detecting device and with a controller coupled to the controllable switch. The memory module has selectable “learn” and “run” modes of operation. In the “learn” mode of operation the controller is programmed to detect and store the time and date when the load is drawing power, i.e. turned on; determine the average time of day the power was turned on;, and the average time between the turning on and off. During the “run” mode of operation, the module produces control signals for automatically turning the controllable switch on and off, thereby supplying power to the load, according to the schedule learned during the learn mode of operation, or a variant of the learned schedule.
