Who should attend?

Anyone interested to strive for relevant LEW qualifications and gain various knowledge areas which in our opinion, a competent LEW should know.

Why choose ON Engineers' LEW Preparatory Course?

We aim to continually update and improve our course’s learning coverage. We use specialized trainers for the different modules. Our trainers are very experienced in their scope of work and include technical trainers who hold the various LEW licences (ie. Electrical Engineer’s Licence, Electrical Technician’s Licence and Electrican’s Licence). We also have a trainer who specializes in the EMA Licensing, CS3 and Turn-One Procedures (for Module 2).

Class participants will also be able use various equipment to practice on an electrical test board to familiarize themselves on the practical aspects of Electrical Testing for Inspection and Turn-On (Module 6).

What are the entry requirements or educational background needed for this course?

There are no entry requirements for this course. The course is open to all, catering specifically to those who wish to wish to apply to be an LEW, or for those who deal with LEWs in the course of their work.

Will I get an LEW licence immediately after completing this course?

An LEW licence can only be granted by the regulator of Singapore’s electricity industry – the Energy Market Authority (EMA).

ON’s LEW Preparatory course is based on our experience in the electrical installation licensing field, and will provide a foundation on what is expected for one to be an LEW.

A Certificate of Attendance will be awarded to course attendees.

Does this course cover the three classes of LEW licences (ie. Electrician / Electrical Technician / Electrical Engineer licences)? Or does it specifically cover only one class?

This course introduces the foundations that an LEW should be well-versed in, and is relevant to all three classes of LEW licences.

After this course, can I carry out high-voltage switching on my company?

The course does not certify you to carry out switching work for your company.

You will need to have valid electrical worker licence to carry out such switching work, or you will need the supervision of the authorised switching engineer.

Can I apply for EMA licence first then enroll for this course or vice versa?

Yes you may. But we strongly advise you to attend the course first before your interview date with the EMA, so that you can be better prepared.
