Wiring of a single phase distribution board is one of the most important electrical works in Singaporean homes. Electricity is very important in every home. It powers your electrical appliances to ease your life. To use electricity in a safe way, every home needs a proper system. One of the main parts of this system is the distribution board. In Singapore, most homes use a single phase distribution board. This article will guide you on how to wire one in a clear and simple way. It is helpful if you want to understand how this system works at home.
What Is Single Phase Distribution Board Wiring?
A single phase distribution board is a box that controls how electricity flows in the house. It takes electricity from the main supply and sends it to different parts of your home. Inside the board, there are devices that protect you from electric shocks and fire. These devices also stop electricity if something goes wrong. Therefore, wiring a single phase consumer unit means the control of the whole house’s electrical supply.
The Guide for Wiring of a Single Phase Distribution Board/ Consumer Unit
Wiring of a single phase distribution board is a technical task that should be undertaken by a professional like LS Electrician Services Singapore, which offers a variety of professional electrician services. Some of their standout services include light bulb replacement, exhaust fan installation, and power socket installation and repair services in Singapore. Here is a procedure they have laid down for wiring a single phase consumer unit.
Getting Ready
Before you start, make sure the main power is off. This is very important. If the power is still on, you will get a shock while working on the distribution board. Always test the wires with a voltage tester to ensure the power is off. Only a trained person should touch live wires.
If you are not sure, ask an expert like LS Electrician Singapore for help. Afterwards, find a safe and dry place on the wall to fix the distribution board. It should be easy to reach and not too high. When the board is fixed on the wall, you can begin to connect the wires.
Connecting the Main Wires
The main wires come from the power meter outside your flat. These are the live wire, the neutral wire, and the earth wire. The live wire is often brown. The neutral wire is blue. The earth wire is green or plain copper.
Connect the live wire to the top of the safety switch. This switch is called the RCCB. Connect the neutral wire to the neutral part of the RCCB. The earth wire goes to a special bar inside the board. This bar keeps all earth wires safe and in one place.
Setting Up the Board
After connecting the RCCB, send the live and neutral wires from the RCCB into the main bars inside the board. These bars spread power to the rest of the circuits. Each circuit will need a smaller switch. These are called circuit breakers. Each room or area in your home should have its own circuit breaker.
Now, fix the breakers inside the board. Each breaker must connect to the live bar. Then, attach a wire from the bottom of each breaker to the wire that goes to the room. The neutral wires also need to go from the room back to the neutral bar. Earth wires are to be connected to the earth bar. These three wires work together to make a safe system.
Final Steps for Wiring of a Single Phase Distribution Board
After you have connected all wires, check that each wire is tight. Make sure no copper wire is showing to avoid shocks in the later stages. Use insulation tape if you see any part that looks unsafe. Clean up the area and make sure there is no water near the board.
Now, you can turn the power on to check the functionality. Start with the main switch and then turn on the RCCB. After that, turn on each circuit breaker one by one. If a breaker trips, there is likely a problem in that part of the home. Check the wiring again if this happens.
Safety Tips for Singapore Homes
When you work on electricity, be extra cautious to remain safe. Only use approved wires and switches. In Singapore, it is the law to use safe parts. Always label each breaker so you know which one controls which room. Do not add too many devices to one breaker. Too much load can overload the breaker and hence cause frequent tripping. Moreover, it is crucial to avoid using wet hands near the board and to keep the children away from the board at all times.
Conclusion
Wiring of a single phase distribution board in Singapore may sound hard, but it becomes simple if you follow the right steps. You must turn off the power before you begin. Then connect each wire to the right place. A good board helps to keep your home safe and powered. If you follow the steps above with care, you can finish the job in a safe way. But if you are not sure, it is always best to call a licensed electrician.
