1. The air conditioner in the cabinet machine is wired on a separate circuit of 4 square millimeters. The kitchen and bathroom each have their own 4-square-millimeter circuit. Lighting circuits use 2.5-square-millimeter wiring, while general outlets are connected using 1-2 circuits of 2.5 square millimeters. 1.5 square millimeter wires are not used in this setup.

2. There should be a minimum separation of 30 cm between strong and weak electrical lines. Additionally, the distance between strong electric conduits and heating pipes, hot water pipes, or gas pipes must also be more than 30 cm to prevent interference and ensure safety.

3. In the same room, power outlets, telephone jacks, and TV sockets should be installed at the same height (unless there are special circumstances). Always follow the standard wiring principle: left zero, right live, and the ground wire should be yellow-green as per national standards. This ensures proper grounding and reduces the risk of electrical hazards.

4. All incoming cables should be protected with locknuts. The conduit should be laid flat without sharp bends. If bends are necessary, they should be made using heat-bending or spring-bending techniques. Connections must be sealed with PVC glue. After laying the conduits, threading should be done before pulling the wires. Any area where the conduit cannot be buried should be protected with a square wax pipe. Exposed wires are strictly prohibited, and ceiling wires must be properly secured to avoid damage or tripping hazards.

5. Weak electrical lines should not have any connectors. For example, TV cables can use a frequency divider, but network cables must not have any joints. This ensures signal integrity and prevents interference or failure.

6. All electrical conduits must be protected. When three sets of wires enter the same junction box, a separate box must be installed for each set. A junction box should also be placed in areas where a ceiling light will be installed to allow for easy maintenance and future upgrades.

7. Once the electrical work is complete, all outlets and lamp wires must be tested using an electric bulb. If the voltage is too high or too low, it must be carefully checked and re-routed if necessary. It is crucial to verify whether a line is live before proceeding to the next step. No further work should be done without proper testing.

8. After the project is accepted, an accurate wiring map should be drawn and provided to the homeowner. It’s also recommended to take photos of the layout for reference and record-keeping purposes.
