A circuit breaker and panel system includes a panel including a base pan having a plurality of base pan electrical connections. A circuit breaker including a housing having a plurality of circuit breaker electrical connections arranged to contact the base pan electrical connections when the circuit breaker is coupled to the base pan. The circuit breaker is rotatably coupleable with the base pan via a pivot joint for engaging the plurality of base pan electrical connections with the plurality of circuit breaker electrical connections per a predetermined electrical connection coupling sequence. One of the housing and the base pan includes a protrusion and the other of the housing and the base pan includes a corresponding recess which, when engaged with each other, retain the housing to the base pan to prevent reverse rotational movement of the breaker with respect to the base pan.

Button assemblies for controlling a seat position and for mounting on a seat panel are provided. The button assemblies may have a button housing having a portion that is configured to position over edges of an opening in the seat panel. One or more flexible retaining members integral to or attached to the button housing are configured to compress through the opening in the seat panel and expand therein positioned opposite an inner surface thereof upon insertion, securing the assembly within the opening.

A support rail and housing assembly is mountable on a housing base. The housings are equipped with electrical contact and/or functional elements which can be strung together. The support rail is mountable on the mounting base even when the housings have already been arranged on the support rail before the support rail is mounted. The support rail is secured to the mounting base by two or more mounting pins which have been placed before the support rail is mounted to the mounting base. The mounting pins and the support rail are designed to correspond to each other such that the support rail can be placed on the mounting pins and locked thereto without using a tool.

An insulating block configured for attachment to an electrical structure without the use of a tool. The insulating block is formed from an electrical insulator. One of the electrical structure and the insulating block may have a clip that is configured to engage a catch surface on the other of the electrical structure and the insulating block without the use of a tool. An opening or recess of the electrical structure may be configured to receive a portion of the insulating block having the clip or catch surface, and the portion of the insulating block may move within the opening or recess from a disengaged position to an engaged position, in which the clip engages the catch surface to securely attach the insulating block to the electrical structure. The electrical structure may be a meter socket enclosure. The combination of the insulating block with the electrical structure.

This application discloses power distribution equipment and a power distribution system. The power distribution equipment includes a power distribution device and a power distribution box, where the power distribution device is capable of being inserted into and removed from the power distribution box; a connection port is disposed at a first end of the power distribution device, where the connection port is used to connect a power cable or a user load line; a power connection terminal is disposed at a second end of the power distribution device, where the power connection terminal is used to plug into a busbar inside the power distribution box; and the connection port and the power connection terminal are connected inside the power distribution device. A design in which the power distribution device is capable of being inserted into and removed from the power distribution box simplifies operation and improves convenience.

An electric power distribution panel is provided. The electric power distribution panel includes a first input bus, a second input bus, a plurality of brackets and a plurality of circuit breaker modules. The first and second input buses are coupled to a first power source and a second power source respectively. The plurality of brackets is electrically connected to the first and second input buses. The plurality of circuit breaker modules are assembled to the plurality of brackets respectively. Each of the plurality of circuit breaker modules includes a circuit breaker and an adapter detachably assembled to the circuit breaker. In each of the plurality of circuit breaker modules, the circuit breaker is electrically connected to the first input bus when the adapter is removed from the circuit breaker, and the circuit breaker is electrically connected to the second input bus when the adapter is assembled to the circuit breaker.

A panel mount for supporting an electronic device at a hole in a control panel and mountable with access to only the front of the panel. It has a housing that slides into a tubular elastomeric grommet. During installation, an expander segment of the housing slides within a bulging segment of the grommet to expand the grommet inward of the hole and for retaining the components within the hole. A tubular male pre-assembly segment on the exterior surface of the tubular housing permits the housing to be pre-inserted partially into the grommet without expanding any part of the grommet radially outward in preparation for inserting the assembled housing and grommet into the panel hole. A withdrawal lock prevents the housing from sliding axially out of the grommet after installation. The withdrawal lock includes a shoulder formed on the grommet and a shoulder formed on the housing.
