Different Types of Electrical Wiring In Singapore

Electrical wiring installation is important for wirings and it can be easily seen in every household or establishment as well as in outdoor areas. There’s a wide range of different electrical wiring types used for electrical works.

Types Of Electrical Wiring According To Cable Covers

• Non-metallic (NM) cables are appropriate in dry areas like the households in Singapore. This cable type typically consists of a live wire, current flow, ground, and neutral wire. 
• Underground Feeder (UF) is a non-metallic cable made up of solid plastic sheathing that covers each of the live wire, neutral and ground wire. The UF cable is not very important in wet areas such as the bathroom, kitchen, and outdoor spaces.
• Conduits are electrical wirings that are made up of metallic or plastic tubing enclosures. These are usually used as house wirings, which are uncovered in the inside walls and ceilings of household.
• Wires with low voltage are surrounded by a plastic cable. These wires are usually small and are used in circuits with a low voltage such as doorbell switches, decorative lights, and thermostats.
• However, in other electrical wirings which are covered in an alloy of lead and aluminum, in which more than 90% of this includes lead. Lead is a strong metal that protects the wires inside from any kind of harm and decay due to moisture and weather.

After knowing the different types of electrical wiring in Singapore, be aware of the signs for when you require electrical wiring upgrade. 

Signs You Require Electrical Wiring Upgrade 

Electrical wirings should be normally checked during renovation and every after a decade. After several years have passed, you can notice the signs that some wirings need to be electrically replaced. What could be the obvious signs you require an electrical wiring upgrade?

We provided a list of signs which are useful for you to determine when you need to upgrade your electrical wirings.

1. Foul and Burning Smell

If you happen to smell a burning odor from your electrical outlet and socket, quickly turn off all your electrical appliances and let it be inspected. Until an electrician checks the problem, it is advisable to not make use of the socket and outlet.

2. Electrical Shocks From Switches

Another sign that you need to change your wirings is when you notice shocking and jolting switches. The reason behind electrical shocks from switches is that the cables are experiencing short circuits to the wires.

3. Buzzing Noise

Have you heard of any buzzing noise coming from the electrical connections? It can be a dangerous sign. The noise from the electrical wires could be caused by the detached connections, outlets, or wobbly wires.

4. Frequently Blown Fuses

If you frequently replace your electrical fuses, it can also be a sign of faulty wiring. That’s an obvious sign that the electricity is not passing through the correct way. It is ideal to contact an electrical contractor to properly check the fuses.

5. Overheating

An appliance from abroad with a high voltage power cannot be plugged in a single port at the same time with other appliances as it may lead to overloading and it overheats the socket. Always check what is plugged into the electrical outlet and also check how many to make sure that the port will not overheat.

Besides knowing the signs of electrical wiring upgrade, remember to also closely study the signs of an electrical wiring repair or replacement.

6 Signs Of An Electrical Wiring Repair Or Replacement

Electrical wiring is an important component in every household as many of us use electrical appliances on a daily basis. Hence, we encourage you to take note of these 6 signs you need an electrical wiring repair and replacement.

Wires wearing out

Any electric wire found in your house is subject to frays due to heat, age, corrosion, and general wear-and-tear. Be aware that screws and nails are likely to damage the wires with their sharp edges. More often than not, rodents also chew on electrical wires, which can lead to eventual damage.   

Immoderate heat damage

Found any scorch marks or warm, burnt spots on your electrical switches or power sockets? These might be obvious signs of improper electrical wiring in Singapore. Do take note that electrical switches and outlets should not be warm to touch, otherwise, it may indicate a case of overheating.  

Circuit breaker tripping

Circuit breakers that frequently trip are an indication of overloading. If there is critical damage on your electrical wires or circuit breaker, an electrical panel replacement might be required to be done. 

A smoky power socket

In any situation concerning electricity, any form of smoke emitting from your power socket is an ultimate warning sign that tells you to replace your power socket. When you notice such things happening, quickly switch off the power. 

Lights beginning to dim

If your lighting installations tend to dim when you switch on some electrical outlets, then it is highly likely that your circuit or electrical wiring is overloaded. To ensure your safety is not compromised, troubleshoot the issue by specifically inspecting both your circuit and electrical wiring.  

Loose connections

Over time, connections between electrical switches and wires loosen due to frequent usage and old age. With this, you should regularly check and ensure all switch plates and outlet covers are in good condition, to ensure your electrical wiring is properly and effectively secured inside its container.

Once you have studied the signs of an electrical wiring repair or replacement, make sure to take note of the electrical wiring mistakes you should avoid.

Electrical Wiring Mistakes You Should Avoid  

Many people prefer doing the electrical work instead, such as replacing electrical wirings, changing of LED light or fan fitting to save money. It is important to know the electrical wiring mistakes you should avoid to prevent electrical problems such as short circuits or power failure.

We have provided some instructions for people who choose to do electrical wiring by themselves.

• An electrical wire has three colors which are black, white, and red. Ensure that all wires are functioning well and avoid connecting them. If the 3 wires are connected caused by miswiring, you may experience short circuits or shocks.

• Many people without enough experience will try stripping the wire to get connections. Although this is a great risk and may result in fires and electric jolts. Therefore, do not try this without seeking the help of an approved electrician.

• Tangled wires need to be rewired by a licensed electrician. Ensure that the wires are accurately connected with the port if you are rewiring. Incorrect positioning of wires can lead to starting a fire.
• Electrical boxes are vital to secure you from electrical sparks or flame, and arranging the boxes will guarantee your protection, which can avoid further harm. It is important not to saturate the boxes as it may result in overloading and can cause fires.
• Ensure that all plastic cables are covered below the walls. Covered plastic cables can help you save money and time rather than rewiring broken or loose wires. There’s a high risk of accidents when you leave exposed cables. 
• Remember to only use 1 electrical wire to the switch and if you are putting several wires, use a nut by pigtail that is attached to the screw of the appliance.

You can follow these guidelines to help you in DIY electrical wiring to prevent electrical issues such as short circuits, electrical overload, and fires.
