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 control system for a standby generator includes a control box mounted in a standby generator enclosure with a control panel coupled to the control box that is selectively openable to provide access into the control box. One or more fasteners may be mounted to the control panel to selectively hold the control panel closed, and one or more generator control components may be mounted in the control box and operated by the control panel.

A bracket system for mounting an electrical box and other components to a ceiling structure can include a support bar and a mounting bracket. The mounting bracket can be configured to receive an end of the support bar and selectively secure the support bar at any of a plurality of positions relative to the mounting bracket.

A wall box may provide adjustable support for a control device, such as a keypad, to allow for level alignment of the control device when mounted to the wall box. The wall box may have an adjustable support frame to which the control device may be mounted. When the control device is mounted to the support frame of the wall box, the support frame may be rotated to adjust the alignment of the control device. In addition, the wall box may comprise one or more projections configured to be received in respective detents in notched surfaces of the control device to allow for adjustment of the alignment of the control device. Further, the wall box may have a modular assembly and may be constructed from a central portion and two side portions at the time of installation of the wall box.

The present disclosure provides a termination box that secures and manages cables and provides an enclosed protected space for connection/splices. The termination boxes of the present disclosure protect the contents therein from being damaged due to impact. They also protect the contents from the environment, including from infestation by insects such as ants. The termination box is easily installed and easily fitted with the adapters, connectors, and cables.

A member junction structure includes a first member provided with a first press-fitting portion and a second press-fitting portion, and a second member provided with a first press-fitted portion and a second press-fitted portion and configured to be installed on the first member by moving in a first direction which is a predetermined one direction with respect to the first member. In a state where the second member is halfway to be installed on the first member, the first press-fitting portion is inserted into the second press-fitted portion, thereby providing a guide for installing the second member on the first member. In a state where the second member is completely installed on the first member, the first press-fitting portion is press-fitted into the first press-fitted portion, and the second press-fitting portion is press-fitted into the second press-fitted portion.

Provided is a circuit assembly that does not need to include test circuit components that are mounted on a control board in a one-to-one relationship with electronic components. A circuit assembly includes a plurality of electronic components; a plurality of control terminals electrically connected to the plurality of electronic components; a holding member that has insulating properties and holds the plurality of control terminals; and a control board configured to output signals to the electronic components via the control terminals, wherein each of the control terminals includes: a first terminal body portion connected to the control board: a pad portion that is electrically connected to the first terminal body portion, is provided along the holding member, and is exposed from part of the holding member; and a second terminal body portion electrically connected to the pad portion and the corresponding electronic component.

There are provided an electric connection box and a wire harness including: a body including an accommodating portion inside the body, the accommodating portion being configured to accommodate an electronic component. The body includes an electric wire holding portion inside the body, the electric wire holding portion having a slit-shaped groove configured to radially sandwich and hold an electric wire extending from a connector to be connected to the electronic component. The groove of the electric wire holding portion includes: a groove inlet portion; a groove deepest portion; and a narrow portion between the groove inlet portion and the groove deepest portion. A groove width in the narrow portion is narrower than a groove width in the groove inlet portion.

A switch box assembly is configured to house a switch box having a bus bar. The switch box assembly includes a holder, a nut housing and a guide. The holder includes a back wall. The back wall includes a slot for receiving the bus bar. The nut housing is configured to house a nut. The guide is disposed on the nut housing and adjacent the back wall, the guide dimensioned to guide the bus bar over a top surface of the nut. Accordingly, the guide prevents the bus bar from hitting the nut during installation.
