How to laying house wire safely!
When laying household electrical wiring, pay attention to the following points:
Plan the wiring route. Plan the wiring route and decide where each socket, switch and lamp will go. Also, decide how the wires will be connected.
Choose the right wires. Choose qualified wires that comply with local standards to ensure safety and reliability.
Safety distance: Keep a safe distance from water pipes, gas pipes, etc. when laying wires.
Use conduit. Use conduit to protect wires when running them inside walls.
Fix firmly. When laying wires, fix them firmly to avoid shaking and damage.
Ground protection: When wiring a house, make sure the grounding wire is connected properly to improve electrical safety.
Professional construction. If you don't know how to do electrical work, ask a professional electrician to do it.
When laying wires at home, follow safety rules to make sure it is done safely and correctly. If you're unsure, ask a professional electrician.
