The load center can be retrofitted to further include a rotational motor, an actuator member, and a guide insert. The rotational motor includes a threaded drive shaft positioned through an aperture formed in the cover. The actuator member is threadingly engaged with the threaded drive shaft. The actuator member is oriented relative to the cover such that a handle of the circuit breaker is positioned through an aperture of the actuating member. Rotation of the threaded drive shaft causes the actuator member to translate such that a first actuating surface of the actuator member engages the handle and switches the handle from an OFF position to an ON position. The handle of the circuit breaker has full range of travel between the ON and OFF positions in response to the actuator member being moved into a neutral position. | 2013-12-19 |
20130335889 | ELECTRICAL JUNCTION BOX - An electrical junction box includes a box body in which electrical parts are mounted and that has a water draining hole provided at a bottom wall part of the box body and a waterproof wall that is provided inside the box body along a periphery of an opening of the water draining hole. The waterproof wall includes a spherical cover wall part standing from the periphery of the water draining hole to cover the water draining hole with an inner spherical surface, and a draining opening part formed at a portion of the spherical cover wall part to allow water exist in the box body to drain to the outside of the box body through the water draining hole. | 2013-12-19 |
20130335890 | Storable Keyboard Having a Pivoting Cover - A keyboard portion is configured to move (with respect to a housing) between a deployed position and a non-deployed position. A cover pivotally couples to the housing and is configured to at least partially cover the keyboard portion when the keyboard portion is in the non-deployed position and to reveal the keyboard portion when the keyboard portion is in the deployed position. By one approach the cover is configured to move the keyboard portion between the deployed position and the non-deployed position as the cover pivots with respect to the housing. | 2013-12-19 |
