A flush mountable electrical apparatus, according to an example, includes an electrical apparatus including a junction box having an open end, an electrical device positioned within the junction box, and a first cover plate to cover the open end of the junction box. The flush mountable electrical apparatus further includes a second cover plate attached to the first cover plate, and a mounting plate to be mounted over a recess in a mounting surface. The mounting plate includes a first opening sized to allow the electrical apparatus to be inserted through the first opening and into the recess. The second cover plate is configured to be attached to the mounting plate to secure the electrical apparatus in position within the recess.

A stub-up is provided for being anchored to concrete slab flooring in which conduit is embedded and through which electrical wiring may be extended. The stub-up comprises a one-piece hollow body having an upper end providing an electrical box and a lower end providing a base permitting the hollow body to be anchored to an underlying concrete slab in an upstanding position. The hollow body provides a wireway for electrical wiring from the slab to the electrical box. Wall structures and methods are also disclosed.

A through wall electrical device including an upper electrical box having a high voltage section for receiving a first electrical receptacle and a low voltage section for receiving at least one low voltage cable, a lower electrical box having a high voltage section for receiving a second electrical receptacle and a low voltage section for receiving the at least one low voltage cable, a hollow tube connecting the upper electrical box low voltage section and the lower electrical box low voltage section, and at least one mounting flange securing each of the upper electrical box and the lower electrical box to an installation wall.

Improvements in machine walls to construct a building or house is disclosed. Adjacent side of the wall sections are tapered and dovetailed that lock-in-place. The dovetails are spaced to reduce the height that one section must be lifted to engage in an adjoining wall section. The footers/base plate will also have integrated earthquake or hurricane hold-downs in the footer/base plate that aligns and can be secured from the foundation to the wall sections. The connection of the wall section to the foundation to have counter flashing at the concrete insert and the wall-to-wall sections can be self-flashed. The wall sections can have GPS locators for positioning the wall sections. Plumbing and electrical conduit creating circuits that can be integrated into the walls and are connected sealed or bonded together.

The present invention provides a base electrical box, and an end portion. The end portion is added to the base electrical box to substantially complete the electrical box. The electrical box also includes at least one intermediate portion that is added to complete the electrical box. The at least one intermediate portion is placed between the base electric box and the end portion.

An electrical box for accommodating at least one duplex electrical outlet including a first side, a second side having a mount opening therein. The electrical box also includes a mounting tube. The mounting tube is mountable to the mount opening. The mounting tube further includes first tubular member having a first length, and a second member fittable within the first tubular member. The second member further includes a tubular main body including a tubular portion fittable within the first tubular member, and a first end including a stop. The first end and stop engage the mount opening in the second side.

The present invention provides a base electrical box, and an end portion. The end portion is added to the base electrical box to substantially complete the electrical box. The electrical box also includes at least one intermediate portion that is added to complete the electrical box. The at least one intermediate portion is placed between the base electric box and the end portion.

Disclosed herein are an electrical wiring structure with connection points arranged on side walls and a building construction method, which can improve convenience of electrical wiring construction and reduce electrical wiring materials. The electrical wiring structure includes a first power wire drawn out of a distribution box and disposed through a first conduit embedded in a concrete-made bottom base of an indoor space, a first joint box embedded at a predetermined height in a first side wall formed in the indoor space and electrically connected to the first power wire, a first light wire electrically connected to the first joint box, and a second joint box embedded at a predetermined height in a second side wall formed in the indoor space and electrically connected to the first joint box by a second power wire disposed through a second conduit embedded in the bottom base of the indoor space.

According to the present disclosure, a switching system for a fixture includes a first switch unit with a first switch actuator and a first power cord with an integrally formed power connector at its distal end. The first switch unit has an electrical receptacle configured to receive a corresponding power connector of a cord electrically connected to the fixture. The electrical receptacle is electrically coupled to the first power cord through the first switch actuator to provide switching actuation to the fixture. The switching system may include a second switch unit that includes a second switch actuator and a second power cord with an integrally formed power connector at its distal end. The first and second switch units are connectable to provide a three-way switching electrical connection.

Disclosed is a wire protector for use in a wire protection system. The wire protector includes a first tubular member and a second member fittable within the first tubular member. The second member includes flexible or bendable fingers which expand after being passed through the first tubular member to lock the second member with respect to the first tubular member. A plurality of wire protectors are placed into studs during construction of a building. Electrical wires are passed through the plurality of wire protectors.
