About Licensed Electrical Workers
What is Licensed Electrical Workers (LEW) in Singapore
Licensed Electrical Workers (LEWs) in Singapore refer to individuals who have obtained the necessary qualifications and licenses to perform electrical works. They are authorized professionals who have undergone training and assessment to ensure their competence in handling electrical installations and systems.
LEWs play a crucial role in ensuring electrical safety and compliance with regulations in various settings, including residential, commercial, and industrial premises. They are responsible for tasks such as electrical wiring, installation, maintenance, and troubleshooting.
In Singapore, the licensing of electrical workers is overseen by the Energy Market Authority (EMA).
The organization sets the standards and requirements for obtaining and renewing licenses, and it also regulates the conduct and performance of licensed electrical workers to ensure public safety.
The licensing framework for LEWs in Singapore includes different classes or categories based on the level of expertise and scope of work. This includes licensed electricians, licensed electrical technicians, and licensed electrical engineers, each specializing in specific types of electrical installations and projects.
Engaging licensed electrical workers is crucial to ensure compliance with regulations, maintain electrical safety, and minimize the risk of electrical hazards.
Classes of LEW
There are three classes of Licensed Electrical Workers (LEWs) available:
The selection of the appropriate class of LEWs depends on the scale and complexity of the electrical installation. Smaller projects like HDB flats generally require the services of licensed electricians, while larger installations like food courts may necessitate the involvement of electrical technicians or even electrical engineers.
| Classes of LEWs | Scale of Electrical Installations |
|---|---|
| Electrician | Not Exceeding 45 kVA / 1000V and Below |
| Electrical Technician | Not Exceeding 150 kVA (Design) / 1000V and Below Not Exceeding 500 kVA (Operation) / 1000V and Below |
| Electrical Engineer | No Limit / Voltage Level subjects to license class (1kV, 22kV, 66kV, 230kV, 400kV) |
Regulatory Requirements of LEW
The regulations governing the engagement of LEWs in Singapore includes the following:
Electricity Act
The Electricity Act provides the legal framework for the generation, transmission, distribution, and use of electricity in Singapore. It establishes the requirements for licensing and regulation of electrical workers.
Energy Market Authority (EMA) Regulations
The EMA is the regulatory authority responsible for overseeing the electricity market in Singapore. They set the standards and requirements for licensing LEWs and ensure compliance with safety regulations.
Building and Construction Authority (BCA) Regulations:
The BCA sets regulations and standards for building construction and safety, including electrical installations. They work in conjunction with the EMA to ensure that electrical works in buildings comply with safety regulations.
By engaging an LEW and adhering to the relevant regulations, individuals and organizations can ensure the safety and compliance of their electrical installations in Singapore.
When to Engage A LEW?
In Singapore, it is necessary to engage a Licensed Electrical Worker (LEW) for various electrical works to ensure compliance with regulations and maintain electrical safety. The following are some situations where it is advisable to engage an LEW:
Whenever there is a need for electrical installation works, such as wiring, switchboard installation, or lighting installation, it is essential to engage an LEW. This applies to both residential and commercial premises.
If you require electrical maintenance or repairs, it is recommended to engage an LEW. They have the expertise to diagnose and fix electrical faults safely and efficiently.
Regular testing and inspection of electrical systems are crucial to ensure their safety and compliance with regulations. LEWs are authorized to perform such testing and inspection, providing assurance that electrical installations meet the required standards.
When establishing new electrical connections, such as for a new property or an additional electrical supply, it is necessary to engage an LEW. They will ensure that the connections are made correctly and adhere to the relevant regulations.
Verify the Validity of a LEW’s License
Before initiating any electrical work at your home or office, it is essential to verify the validity of a worker’s license.
Every Licensed Electrical Worker (LEW) is provided with a card that contains their photograph, name, identity card number, and license number.
Please ensure that you thoroughly check the LEW’s card to confirm its authenticity prior to proceeding with any electrical tasks.
