Container House Circuit Wiring Diagram

The circuit wiring of container houses should follow general circuit wiring principles and be reasonably designed according to their spatial characteristics. Here are the specific key points:

I. Principle of Separating Strong and Weak Currents The strong-current box (controlling lighting, sockets, and high-power appliances) and the weak-current box (controlling network, telephone, and TV signals) should be installed separately to avoid electromagnetic interference. The distance between the wiring of strong and weak currents should be no less than 30 centimeters. When they cross or overlap, the crossing part should be wrapped with aluminum foil wire to prevent signal interference. For example, the lighting circuit (strong current) and the network cable (weak current) should be laid in separate troughs, and the crossing part should be wrapped with aluminum foil.

II. Wire Specifications and Circuit Design Choose the thickness of wires according to the power of appliances: the higher the power, the thicker the wire. For example, high-power appliances such as air conditioners and water heaters should have separate circuits and use wires of 4 square millimeters or above; ordinary sockets can use 2.5 square millimeter wires; and lighting circuits can use 1.5 square millimeter wires. Separate circuits can avoid overload risks and facilitate troubleshooting.

III. Wiring Process Specifications

1. Arc Instead of Angle: The arc at the turning point of the wire conduit should be greater than 90 degrees to ensure that the wire can be flexibly pulled and facilitate later maintenance.
2. Press Instead of Wind: When wires cross during wiring, let one of the wires press down to avoid signal attenuation or increased resistance caused by winding.
3. Oblique Instead of Straight: When wires go up the wall, appropriate arc-shaped oblique slots can be made according to the situation to reduce damage to the wires caused by right-angle bends.
4. Straight Instead of Bent: The straight-line distance between two points is the shortest. Unless in special cases (such as avoiding obstacles), no elbows are allowed to reduce resistance and signal loss.

IV. Joint Treatment and Safety Protection When making joints with several wires, the winding method should be no less than 5 turns, and then wrapped with 3 layers of waterproof tape and insulating tape respectively to prevent electric leakage or short circuits. For example, when connecting sockets, the joints of the live wire, neutral wire, and ground wire should be strictly treated according to this standard, and ensure that the joints are located in the junction box.

V. Balancing Economy and Practicality The capacity of circuit renovation should be just enough and avoid blindly pursuing the thickness of wires. For example, ordinary lighting circuits do not need to use 4 square millimeter wires, and 1.5 square millimeter wires can meet the requirements, which can not only reduce costs but also minimize material waste. At the same time, wires that can pass through the wall do not need to run on a separate circuit to improve space utilization.
