How to Install Hidden Wiring in Container Houses

Installing hidden wiring in container houses requires combining their structural characteristics, achieving it through reasonable planning of wiring routes, selecting appropriate materials, and standardizing construction. The specific methods are as follows:

Planning Wiring Routes

• Utilizing Internal Corners and Bottom Spaces: The internal corners of container houses are angles recessed into the walls. People standing on the side or front are less likely to notice the wiring at the corners, so wiring can be arranged in these internal corners to achieve a hidden wiring effect. At the same time, people rarely pay attention to the bottom of walls, so electrical circuits can be considered for placement at the bottom of walls and concealed with baseboards. When selecting baseboards, prioritize those with grooves on the back or those custom-made with grooves on the back to facilitate placing wires.
• Using the Back of Furniture: If there is furniture inside the container house, wiring can be arranged on the back of the furniture to conceal it. However, this method is only suitable for small-area wiring, and the wiring will be exposed when the furniture is moved later, so it should be used with caution.
• Leveraging Stair Structures: For container houses with a loft structure, if you do not want to penetrate the floor slab, consider arranging the wiring at the bottom of the stair railing or in the internal corners of the stair treads. If there are grooves at the bottom of the stair railing, they can be directly utilized; if not, grooves can be made with a machine, and then the wiring can be covered with electrical tape in a color similar to that of the railing.

Selecting Appropriate Materials

• Wires: Appropriate wires should be selected, considering their electrical and mechanical properties. The current-carrying capacity of the wires should meet the load requirements of the circuit and have some margin. At the same time, they should have sufficient voltage resistance, insulation properties, and mechanical strength. Generally, plastic-sheathed wires are commonly used for indoor wiring.
• Conduits: When installing hidden wiring, the wiring should be protected with rigid sheaths (rigid pipes), such as steel pipes or flame-retardant rigid polyvinyl chloride pipes (rigid PVC pipes), to protect the wires from hard scratches. Soft conduits are prone to 'dead bends', and once the wiring fails, it cannot be repaired. In contrast, rigid pipes combined with standardized processes can turn the wiring into 'live wires', facilitating replacement during maintenance.

Standardizing Construction Procedures

• Grooving: According to the planned wiring routes, grooves should be made on the walls or floors of the container house. The width and depth of the grooves should be sufficient to bury the wire conduits. At the positions of wall-penetrating holes, the wire conduits should be bent carefully to ensure that wires can still be threaded through after bending. Then, the wire conduits should be fixed to the walls with special clamps or saddle clips.
• Threading Wires: When threading wires, the wires can be directly threaded into the protective conduits, but it is difficult at bends. Therefore, the wires can be threaded when placing the plastic conduits, or a lead wire can be pre-threaded in the plastic conduits for backup.
• Installation and Repair: Bury the junction boxes for sockets and switches into the walls, leaving only the sockets and panels exposed. After all the wires are threaded, connect the switches and sockets, conduct a power-on test to confirm that all socket circuits are powered on, and then repair the chiseled walls and floors with cement mortar to make them flat.
