If you are looking to install a ceiling fan, you will have to determine how many volts your fan needs. This can be done by checking the voltage on the distribution board and comparing it to the voltage of the fan. You should connect the green / yellow wire of the fan to the ground wire on the main board. Then, connect the blue wire to the blue neutral on the distribution board.

The neutral wire is a very important part of your electrical system. It provides a return path for electrical current in a circuit and is typically connected to a single conductive piece of metal known as the neutral bus bar. Although the neutral wire is small, it still has the ability to carry electricity.
Wires in your electrical system are wrapped in insulating casings that tell you what they do. The wires are color-coded to make it easy to identify what kind of wire you need. The ground wire is green with a yellow stripe on it. The hot wire is black and connects to an electrical outlet from a switch. If your switch is 240-volt, the hot wire is red. Blue wires are used for ceiling fans and three-way switches. White wires are neutral.
When installing a fan, or adding a light kit to it, you must run a new wire to the switch box. This wire should be a three-conductor wire, or “14-3.” Local codes may also specify the wire gauge. You must also split the incoming hot wire into a “Y” for each switch. The black wire is then connected to the screw in switch No. 1.
230V load ceiling fan
If you have a 230V load ceiling fan, you must make sure that the neutral is connected. A floating neutral can cause problems, such as overvoltage and low voltage. A proper neutral connection is important for the safety of your fan and your home. You should never use a ceiling fan without a neutral wire.
The black and red wires in a ceiling fan power box are usually from the same branch circuit source. You must check the label on the power box to determine where to plug in your ceiling fan. The ceiling fan’s power box should have wire nuts or push connectors on the end of each wire.
Once you’ve done this, you’re ready to connect the fan’s light kit. You’ll also need to run a new wire. Make sure you use “14-3” wire, which is a three-conductor wire. Your local codes may also require a particular wire gauge. You’ll also need to split the incoming hot wire into a “Y” for each switch. Once you have done this, connect the black wire to the screw on switch No. 1 so you can identify the hot one.
