Malaysia’s electrical wiring system has three things must know: external, internal, and three-phase. TNB installs external wiring to carry power from the 3-phase supply outside the house. External wiring costs vary depending on the type of house unit and connection cable used. Internal wiring, on the other hand, is the wiring that runs throughout the house to distribute power lines and can cost up to RM10,000. The process can take up to two weeks depending on the wiring plan, while upgrading the external wiring can be completed in a day.
Electrical wiring systems are complex networks of cabling and electrical devices. Some houses have lighting fixtures and three-phase power. These systems are complicated, but they are required because they provide power to devices and appliances. The wiring diagrams may appear complicated, but understanding them will make working with them easier. Let’s look at the different types of electrical wiring in Malaysia. You’ll see how they’re organised and what they’re all for.
Safety Precautions
Malaysian plugs are G, with three rectangular pins arranged in a triangular pattern. Malaysia’s electrical supply is 240V and 50Hz, so electrical appliances with a different voltage or frequency must be converted before being used in Malaysia.
When using electrical appliances, turn them off whenever sparks appear. Before servicing or repairing them, disconnect the power cord. Never leave an unattended electrical appliance plugged in a wet area. This is especially important for appliances that have cords. Make sure that these cords are out of reach of children. To prevent electrical injuries, you can also install child-proof plugs. Finally, when using electrical appliances, always wear rubber-soled shoes.

Distribution Board
A distribution board regulates the electrical energy that enters your home. It houses all of the plugs and electrical devices that are connected to it. This device, also known as a fuse box or circuit breaker, is owned by the homeowner. In general, the system is made up of single-phase alternating current (AC) systems with two live wires. The majority of Malaysian homes have a single-phase alternating current (SAC) wiring system with two live wires.
3-Phase Electrical Wiring System
Three-phase systems are more efficient than single-phase systems. It produces twice as much power as a single-phase system. The good news is that three-phase wiring systems do not necessitate twice the number of wires as single-phase systems. They are simply three times more efficient and cost-effective. Both systems have advantages, but you should understand how they work.

External Wiring vs Internal Wiring
Internal wiring and external wiring are the two basic types of electrical systems. Internal wiring entails wiring within the home and can range in price from RM2,000 to RM10,000. Internal wiring can take up to two weeks, but external wiring can be completed in a single day. Furthermore, while internal wiring is generally more expensive, upgrading your power supply is not always necessary. If you have three or more air conditioners running at the same time, or if you have power outages, you must upgrade your wiring.
