In an example embodiment, a junction box may include a flashing. The flashing may define a first groove. The first groove may be disposed relative to a first center axis on a first plane. The junction box may also include a housing. The housing may include a bottom portion. The bottom portion may define a second groove. The second groove may be disposed relative to a second center axis. The second center axis may be coincident with the first center axis in a direction that is substantially parallel to the first plane of the first groove. In addition, the second groove may be located on a second plane that is substantially parallel to the first plane of the first groove. Further, the second groove may be configured to indicate a suitable hole position in the bottom portion.

A junction box for electrical wiring includes a housing and a base plate. The housing is adapted to removably connect with the base plate to house the electrical connection. The base plate is secured to a support beam to provide stability to the junction box. The housing and the base plate are either of a unitary structure, or include tabs and/or attachment flanges that provide additional access and stability to the electrical connection, while reducing strain. The junction box may be secured to the support beam via a telescoping bar hanger.

A safety assembly having a cover plate for mounting to a pre-existing electrical receptacle and a safety housing for removably attaching to the cover plate. The safety housing is a unitary construction having a front end and a back-end wall with four side walls extending therebetween to provide an open interior, wherein the front end is substantially open and configured for securing to the cover plate. The cover plate has one or more pairs of slots positioned near an opening in the cover plate for exposing a socket of the electrical receptacle and the safety housing comprises one or more attachment mechanisms configured to removably engage with the one or more pairs of slots to removably couple the safety housing the cover plate.

A fuse box for a battery of a vehicle includes: a lower housing having a space in which a fuse is housed and a bus bar for electrically connecting the battery and the fuse is seated; a plate-shaped upper housing having a through hole formed at a central portion thereof and a first extending portion extending upward along a circumference of the through hole, where the upper housing is assembled on an upper side of the lower housing; and a fuse cover that is coupled to an upper side of the upper housing to cover the fuse exposed through the through hole of the upper housing.

An adjustable in-ground box assembly is configured to form a protective enclosure for an in-ground utilities device. The adjustable in-ground box assembly includes an outer box and an inner box. A reinforced vertical interior fastener panel is formed with a wall of the outer box, and includes a number of pre-formed outer box fastener holes arranged in spaced apart vertical columns. The inner box includes a number of inner box fastener holes arranged in a horizontal row. The height of the in-ground box assembly is vertically adjusted by aligning the inner box fastener holes with horizontally-situated outer box fastener holes at a selected height on the vertical fastener panel. The tilt of the in-ground box assembly is adjusted by aligning the inner box fastener holes with selected diagonally-situated outer box fastener holes.

A junction box cover assembly for attachment over an opening in an electrical junction box allows for a concealed connection to avoid detracting from the lighting fixture. The assembly includes a cover plate capable of being mounted to a junction box, the cover plate having an opening there through defined by a first threaded collar extending from the cover plate, a hub having a flange radially extending from a periphery of a second threaded collar defining a passage and configured to attach to the first threaded collar of the cover plate, and a circular insert detachably connected within the passage defined by the threaded collar, the circular insert having an opening for passing electrical wiring from the junction box through the passage, out the insert opening and to a light fixture. The cover plate and the radially extending flange somewhat sandwich a surface, such as drywall or wallboard, and the flange is configured to permit covering with spackling paste or joint compound to conceal the flange.

A mounting bracket for an electrical box can be configured for use with a support that has a first and a second rail. The mounting bracket can include a first attachment device that is secured to mounting body and a second attachment device that is secured to the mounting body opposite the first attachment device. To secure the mounting bracket to the support, the first attachment device can be configured to engage one of the first rail or the second rail and the second attachment device can be configured to engage the other of the first rail or the second rail. Each of the first and second attachment devices can include a first arm configured to extend on a first side of the corresponding first or second rail, and a second arm configured to extend on a second side of the corresponding rail, opposite the first arm

This application provides a gateway device. The gateway device may include a base and a cable waterproof structure disposed on the base, the base includes at least one network interface, and the cable waterproof structure includes a cable plugged into the network interface and a cover that covers the network interface. The cable includes a cable body and a network interface plug fastened to an end portion of the cable body. A sealing member is disposed at a joint between the cable body and the network interface plug. A threading hole through which the cable is threaded is disposed in the cover, and the sealing member is attached to the threading hole through interference fit. Effective waterproof for the cable can be implemented through interference fit between the sealing member and the threading hole of the cover.

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.
