Container House Circuit Diagram

The circuit diagram design for container houses should integrate their structural characteristics and power requirements, covering core aspects such as the layout of strong and weak current boxes, wire specifications, safety protection devices, and circuit design. Below are the specific design points:

1. Layout and Functional Division of Strong and Weak Current Boxes The strong current box in a container house should centrally manage high-power equipment such as air conditioners, sockets, and lighting, while the weak current box is responsible for low-voltage lines like TV, telephone, and network. These two should be installed independently to prevent strong current interference with weak current signals. For example, the strong current box can be placed near the entrance of the house for easy maintenance, while the weak current box can be adjacent to the strong current box but physically isolated to ensure signal stability.

2. Matching Wire Specifications with Load Capacity Choose wire specifications based on the power of electrical equipment:

• Lighting Circuit: Use 2.5 square millimeter copper wires to meet the needs of low-power devices like LED lights.
• Socket Circuit: Regular sockets use 2.5 square millimeter wires, while high-power appliances such as air conditioners and water heaters require 4 square millimeter wires.
• Inlet Wire Specification: It is recommended to use 6 square millimeter fire-resistant and flame-retardant copper wires for the main inlet wire to ensure overall electrical safety. The wire laying should be marked with pipe diameters (such as PVC20 pipes) and laying methods (such as WC concealed laying in walls) to avoid damage during later construction.

3. Configuration of Safety Protection Devices

• Air Switches: The main switch should be a 32A/3P circuit breaker, and branch circuits should be equipped with 16A or 20A circuit breakers according to the load to prevent overloading.
• Leakage Protectors: All socket circuits should be installed with leakage circuit breakers (such as RCBO C16A/1P+N/30mA) to automatically cut off the power in case of electric shock.
• Lightning Protection Devices: Install an SPD-40/4 lightning surge protector at the inlet end to prevent lightning strikes from damaging equipment.

4. Circuit Design and Functional Zoning

• Air Conditioning Circuit: Set up independently to avoid sharing lines with other high-power appliances.
• Lighting Circuit: Use a parallel connection method to ensure that a single light failure does not affect the overall lighting.
• Special Equipment Circuit: For container energy storage systems, refer to the 'Electrical Schematic Diagram of Container Energy Storage Busbar Cabinet' to clarify the power input, protection devices (circuit breakers, fuses), and output processes.

5. Diagram Annotation and Construction Specifications The circuit diagram should be annotated with the box number of the electrical box (such as 31AL-1), circuit sequence numbers (W1/W2), wire specifications (BV3×2.5), and laying methods (CC concealed laying in the ceiling). During construction, follow the requirements of the 'Indoor Distribution Box Electrical System Diagram' to ensure that the electrical box is installed with a vertical deviation of ≤3mm, and the power wire of the fuse is connected to the middle contact to avoid electric shock risks.
