Wiring is one of the most overlooked yet critical details in home renovation, as it safeguards your electricity safety for decades to come ✨
Below is a practical guide to help you steer clear of all common pitfalls.
Stick to three core principles when buying wires: opt for products with national standard CCC certification, choose proper specifications for different usage areas, and purchase well-known brands from authorized stores. This will fully secure your household electricity safety.
✅ Quick Ways to Judge Wire Quality
- Check markings: Standard wires are printed with the CCC logo, manufacturer information and specifications. The prints are wear-resistant and hard to rub off. Non-standard wires usually have vague or even missing markings.
- Check copper cores: High-quality cores are purplish-red, glossy and soft. Inferior ones look dark or pale, stiff and prone to snapping.
- Test insulation: Bend the wire repeatedly. Qualified insulation stays flexible and crack-free. Low-quality insulation made of recycled plastic breaks easily, and nail scratches will leave obvious marks.
- Flame resistance test: Flame-retardant wires extinguish themselves once away from fire, producing little smoke and no unpleasant smell. Poor wires burn fiercely with thick black smoke and pungent fumes.
- Check length and weight: For a standard 100-meter wire, the length error shall not exceed 5%. Products that are underweight or shorter than labeled are definitely shoddy goods.
Recommended Wire Sizes for Home Use(Copper wires are highly recommended for home renovation. Aluminium wires are not advised.)
- Lighting circuits: 1.5 mm², economical and fully functional
- Regular sockets: 2.5 mm², suitable for most daily household appliances
- Air conditioners, water heaters & kitchen appliances: Use wires of 4 mm² or thicker with dedicated circuits to prevent overheating caused by overload.
- Main incoming wire for large houses & villas: 6 mm² or thicker, selected according to actual power load.

⚠️ Friendly Reminder: Never buy wires sold far below the market price. Most of them have undersized cores or impure copper. Saving a small sum now will lead to costly rework later.
Remember to ask for invoices and product certificates, and keep all documents properly.
Every detail matters in renovation. Choose qualified wires, and enjoy a safe and comfortable living environment.
