Some appliances may require dedicated electrical points or circuits.

Electrical planning should also take place before kitchen cabinets are installed so that wiring and electrical points are positioned correctly.

7. Ceiling Fan Installation

Ceiling fans require appropriate electrical points and secure installation.

Electrical installation may include:

• Fan point
• Switch
• Regulator or control
• Wiring
• Additional lighting point if the fan includes a light

The installation should also consider the ceiling structure and the manufacturer’s installation requirements.

8. Distribution Board Installation and Upgrading

The distribution board, commonly called the DB box, distributes electricity to different circuits in the property.

It may contain:

• Main switch
