1. Wire configuration principles
Functional division: Divide the wires according to the functions of the rooms, such as living room, bedroom, kitchen, bathroom, etc., and configure them according to different needs.
Load calculation: Ensure that each wire can handle the expected load to avoid the risk of fire caused by overloading.
Safety distance: Electric wires should avoid crossing with water pipes, heating pipes and other facilities and maintain a safe distance.

2. Wire type
Wires for different purposes:
BV line: commonly used for indoor fixed wiring.
BVR cable: Flexible cable, suitable for mobile appliances or equipment.
Fire-resistant cables: used in public places and high-risk areas.

3. Wire installation method
Measure and Mark: Before installation, measure the required wire length and mark the location on the wall.
Laying electrical conduits: When connecting wires inside the wall, use electrical conduits to protect the wires to prevent them from getting wet or suffering mechanical damage.
Junction box installation: The junction box should be installed in a location that is convenient for inspection and maintenance, so as to facilitate future power connection and maintenance work.
Using sockets: According to usage needs, reasonably configure the position and number of sockets. It is recommended to install enough sockets in places such as next to the bed, next to the sofa, and on the kitchen workbench.

4. Security considerations
Professional installation: It is recommended that the installation be performed by a professional electrician to ensure compliance with local electrical safety standards.
Inspection and acceptance: After installation is completed, a comprehensive inspection must be carried out to ensure that all wires are connected correctly and that all sockets and switches are tested to be functioning properly.

5. Other Tips
Future expansion: Consider future needs (such as multimedia equipment) and leave room for expansion when designing.
Record the circuit: Keep a record of the circuit diagram for future reference during maintenance and layout.

Ensuring that electrical wiring is configured and installed in accordance with these principles can greatly improve the safety and comfort of the living environment. If you have more specific needs or questions, feel free to let us know!
