This application discloses a circuit breaker and a power distribution box, and relates to the field of communication device technologies. The circuit breaker includes a housing, a control apparatus, and a current signal collection mechanism, an operating mechanism, and a contactor mechanism that are disposed in the housing. The current signal collection mechanism has a first fixed contact and a second fixed contact that are electrically connected. The operating mechanism has a rotating part and a first moving contact. The first moving contact is electrically connected to a first electrode cable inlet port of the circuit breaker. Rotating the rotating part may make a circuit between the first moving contact and the first fixed contact connected/disconnected.

The invention relates to a wall feedthrough having a frame which is divided by at least one intermediate web into at least two chambers, wherein at least one grommet of elastic material is arranged in each of the chambers, and wherein the grommet has at least one passage opening for accommodating an elongated object to be passed through the wall. It is provided according to the invention that two adjacent grommets, having an intermediate web between them, are respectively designed in such a way that they overlap the intermediate web on at least one side of the frame in the longitudinal direction of the elongated objects over the entire height of one side edge of the grommet and make sealing contact with each other.

An outlet enclosure for enclosing an electrical outlet to cover the electrical outlet and its electrical socket. The outlet enclosure includes a base plate and an outlet cover or holder which wraps partially around the electrical outlet to allow access to the electrical socket. The outlet cover or holder includes tracks extending in a vertical direction along its outer surface. An outer cylindrical cover wraps completely around the outlet cover or holder. The outer cylindrical cover slides vertically via the tracks over the outlet cover or holder from a lowered position fully enclosing the outlet cover or holder to a raised position exposing the electrical socket to allow access to the electrical outlet so that a plug can be inserted into the socket of the electrical outlet. When the outer cylindrical cover is lowered, it protects the electrical outlet from exposure to the elements.

A connector system includes a first connector configured to be electrically connected to a predetermined device required for air discharge and to introduce air discharged from the predetermined device into the first connector, a first connection line surrounding a first cable electrically connected to the first connector, one side of the first connection line being connected to the first connector, and a second connector connected to an opposite side of the first connection line and electrically connected to the first cable, wherein the first connector, the first connection line, and the second connector are configured to communicate with each other such that the air introduced into the first connector is discharged through the second connector after passing through the first connection line.

There is provided an electrical junction box including: a bolt holding portion that includes a stud bolt and a bolt holding portion body configured to hold the stud bolt; a first holding portion that includes a first busbar provided with a first connection terminal and a first holding portion body configured to hold the first busbar and a first electronic component; and a second holding portion that includes a second busbar provided with a second connection terminal and a second holding portion body configured to hold the second busbar and a second electronic component. The bolt holding portion, the first holding portion, and the second holding portion are assembled with a nut in a connection state in that the stud bolt is passed through the first connection terminal and the second connection terminal, and in that the first busbar and the second busbar are overlapped with each other.

A horizontal surface cover with a cover plate, at least one opening, and at least one access door. The cover plate is configured to cover an electrical device within an electrical box. The at least one opening extends through the cover plate and is sized to allow access to the electrical device through the at least one opening. The at least one access door is sized and shaped to fit within the at least one opening, and has a hinge with a hinge axis. The at least one access door is configured to translate along the hinge axis and rotate about the hinge axis to move between a closed position and an open position. The at least one access door is aligned with and inside of the at least one opening when in the closed position, and is misaligned with the at least one opening when in the open position.

A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

A remote control device may be mounted to a structure. The remote control device may include a control unit, a base, a faceplate, an adapter, and a mounting plate. The adapter may be configured to be attached to the faceplate. The adapter may be configured to be secured to the structure. The mounting plate may float between the adapter and the structure when the adapter is secured to the structure. The mounting plate may include a frame, a mounting tab, and a plurality of spring arms. The mounting tab may extend from the frame, for example, a platform on the frame. The mounting tab may be configured to prevent rotation of the base of the remote control device when the base is attached to the mounting plate. The plurality of spring arms may be configured to bias the mounting tab away from the structure.

An enclosure for breaking out a trunk cable includes: a base having a generally flat surface adapted for mounting to a mounting surface; a shell having a front and two side walls extending from opposite sides of the front and two opposed end walls, the side walls of the shell mounted to the base to form a cavity; a plurality of connectors mounted to each of the side walls; and a trunk cable routed into the cavity through one of the end walls, the trunk cable comprising a plurality of power conductors and/or a plurality of optical fibers.
