4 tips to be careful when using the lower switch junction box
Boxes Connection is vital in all electrical and building construction projects. When it comes toelectrical connection, the wires are buried behind walls, and the outside of the wire is covered with a wire tube for protection.
In the connection part, long wires or tubes are placed to guide the wire into a junction box as a transitional part. The wire tube and the junction box are connected, and the wire tube is placed inside the box for connection. Thus, the inner part of the junction box is equivalent to the intersection point, where the wires are organized and protected.
When installinga switch junction boxin the wall, attention to quality should be paramount. The electrical junction box deals with the connections of the switches, and since the wall switches are the source of electricity in the room, we have to pay attention to the quality of the junction box. We should consider the quality of the switch junction box in terms of appearance, structure and materials, as well as its ability to resist pressure.
- Appearance: A normal switch junction box is generally hidden inside the wall, and requires good wiring planning before the wall is built. Nowadays, the use of surface-mounted junction boxes has become popular, especially in homes of historical value. In addition to meeting safety and its structure similar to hidden models, the surface-mounted junction box also takes into account aesthetic aspects.The junction box should be of appropriate depth so as not to interfere with the furniture in daily use. It is preferable that the bottom and the parts in contact with the wall be flat to avoid large gaps after installation and so that dust and impurities do not accumulate.The junction box cover should be smooth and easy to clean. It is recommended to use new materials such as PVC to achieve this goal, as their surface is smooth and easy to clean.Regarding materials, attention should be paid to using new materials to manufacture the junction box to ensure durability and quality. It is preferable to avoid using secondary or recycled materials to ensure sustainable performance and the best protection of wires and connections.
The use of flame retardants in the production of junction boxes contributes to environmental protection and improves the overall performance of the product.
- Basic Installation:Given the complexity of wire placement for end-consumers, and the possibility of adding additional wires in the future, the design of junction box holes becomes vital. The design should be as hidden as possible in all directions to keep the walls beautiful. Access holes should be conveniently shaped, easy to remove without leaving any traces, and should be sized to match the size of the pipes.As for the junction box installation, it generally needs to be done by professional electricians. But for simple wiring or replacing an old junction box, many consumers may choose to do it themselves. Therefore, precise details must be available in the design of the junction box. The screw holes, which will be used to secure the keyboard, must be very precise, making it easy to remove the screws easily. This avoids any incorrect deflections or other problems, making the installation process much easier for end consumers.

- Material:The junction box common in daily life is usually made of metal material, such as iron, and PVC material. It is shown that the metal junction box is generally superior in grounding, fireproof performance, and structural rigidity. For PVC and other materials, the insulation performance is usually better. Depending on different environments, different materials are selected for the junction box.It is important that the materials used in the junction box are flame retardant and resistant to high temperature. The material of the junction box must be safe and have flame retardant properties, to avoid problems caused by internal wiring that may cause fires. With so many wires, panel switches and sockets being connected, internal heating definitely occurs. According to IEC60670-1, the junction box body must reach 850°C to ensure its flame resistance.In addition to the housing material of the junction box, it has two screw holes for fixing the board. The quality of these openings, their materials and the method of their installation must be of high quality. When using the plugs in the lower junction box of the wall switch, the socket is frequently plugged and unplugged. If the screw holes are not of good quality, the screws may be damaged or even fall off, causing the board to separate from the junction box. Therefore, bolt holes must be difficult to remove, resistant to rust and corrosion, and are usually enhanced with colored zinc plating for durability.
- Compressive Strength:Most junction boxes are installed in the walls in a pre-buried manner, and over time, the wall may be subjected to a certain pressure which can cause the junction box to deform. This deformation is due to the inconsistent installation of the keyboard that comes after it, or long-term use may affect the condition of the keyboard. Therefore, the junction box housing must be able to withstand the pressure of the surrounding structure.In addition to using high-quality and strong raw materials, the structure of the junction box can be strengthened to improve its compression resistance. The external appearance and internal structure of the junction box, along with its resistance to compression, are key points for testing its quality. Since the junction box is an essential part of daily electrical supplies, it protects the wires and ensures the safety of using electricity.
