1.1 Assessment Structure, Eligibility, Fees, and Application Process

Quick Summary: The EMA Electrician Licence assessment has three stages: a 3-hour written test (Sections A–E, 240 marks; pass = overall ≥ 50% and ≥ 75% in Section E on Regulations), a practical fault-finding test, and a technical competency interview. Apply via the EMA ELISE portal with a S$50 application fee; the licence fee is S$30. A written pass remains valid for 3 years.

1. Purpose of the Assessment

The Energy Market Authority (EMA) assesses every applicant for an electrician's licence — the Licensed Electrical Worker (LEW) class entitled to design, install, repair, maintain, operate, inspect, and test low-voltage installations not exceeding 1,000 V and an approved load of 45 kVA — to confirm technical competency before a licence is granted. After an application is accepted, the candidate's competency is assessed through a written test, a practical test, and an interview, in that order.

2. The Written Test (Stage 1)

The written test is conducted approximately once every two months. Its structure and marking are fixed:

Passing Criteria and Validity

• Duration: 3 hours.
• Pass mark: an overall score of at least 50%, provided the candidate also scores at least 75% in Section E (Regulation). A candidate who totals 55% but misses the Section E threshold fails the test.
• Validity: a written-test pass is valid for 3 years. Candidates must obtain the electrician licence within three years of passing; otherwise the written test must be retaken.
• Permitted materials: a non-programmable calculator only. Mobile phones, tablets, and any electronic communication devices are prohibited.

Written Test Syllabus (EMA “Additional Information for Application to become Licensed Electrician”, Ver. 04_2025_R1)

• (a) Electricity Act and relevant Electricity Regulations: definitions; authority conferred by each LEW licence class; responsibilities of each licence holder; connection of installations to the supply line; modifications; testing compliance; and the person responsible for an installation. References: Electricity Act Part 9; Electricity (Electrical Installations) Regulations Parts I, II, III and V; Electricity (Electrical Workers) Regulations; and the Electricity (Licensing of Electrical and Supply Installations) (Exemption) Notification. (Covered in Chapters 1, 7 and 8 of this guide.)
• (b) Domestic and Industrial Installations: single-line diagrams (up to 45 kVA); installation design (maximum demand, protective device ratings, cable sizing with correction factors, voltage drop, segregation); protection against electric shock; earthing and bonding; AC and DC supplies; rotating machines; small generators; and pre-commissioning / turn-on inspection and testing, including temporary installation safety and the Statement of Approval. References: SS 638, SS 650 Parts 1 and 2, SS CP 83 Part 2, and the Handbook for application of an electrical installation licence. (Covered in Chapters 2–8.)

3. The Practical Test (Stage 2)

Candidates who pass the written test are invited to a practical test on a wired electrical installation mock-up not exceeding 45 kVA containing several deliberate electrical faults. Candidates must demonstrate the ability to identify non-compliance with the codes of practice and to troubleshoot common faults — new cable colour code errors, wrong circuit or colour-code labelling, open circuits, short circuits, wrong phasing, and wrong polarity.

• Bring your own instruments: a continuity tester / multimeter and screwdrivers (Philips and flathead); hand gloves if preferred.
• Dress code: sleeved shirt, long pants, and covered footwear are mandatory.

4. The Technical Competency Assessment Interview (Stage 3)

Candidates who pass the practical test proceed immediately to an interview with an assessment panel. The five assessed topic areas are:

1. Single-Line Diagram interpretation: standard graphical symbols (SS CP 83 Part 2); information an SLD must carry (current-carrying capacity, short-circuit capacity, protection or measurement current transformer details, busbar size); protective device settings; outgoing circuit types and ratings; instrumentation and metering requirements; generators or other supply sources; earthing type and requirements.
2. Protection for electrical safety: basic and fault protection against electric shock; protection against thermal effects (heat, ignition, fire); overcurrent protection with built-in devices and external protection relays; selection of protective and isolation devices and lock-out/tag-out for isolation.
3. Earthing and bonding: design and installation requirements of protective earthing and bonding; TT and TN-S systems used in Singapore and their protective measures; the difference between earth resistance and earth fault loop impedance and their acceptable limits.
4. Testing and commissioning procedures: visual inspection against design requirements; pre-turn-on tests (continuity, insulation resistance, polarity) and the importance of test sequence; safety measures for testing personnel; post-turn-on tests (rotation, voltage measurement, RCD tests).
5. Temporary installations: requirements of SS 650 Parts 1 and 2; basic and fault protection in temporary installations; generator earthing for temporary installations; and the application of Socket Outlet Assemblies (SOA) on construction sites.

5. Eligibility and Qualification Routes (Regulation 4)

An electrician's licence may be issued to any person who satisfies one of four statutory routes:

The applicant must also be currently involved in electrical work that an electrician is authorised to perform.

6. Application Process and Fees (ELISE)

1. Prepare documents: photo ID (passport size); NITEC or other academic certificate; preparatory course certificate (if applicable); testimonials from current/previous employers or the project LEW. Applicants aged 65 or above need a medical Certificate of Fitness from a registered medical practitioner. Self-employed applicants must have up-to-date MediSave contributions (or an active GIRO arrangement) before EMA will issue the licence.
2. Apply and pay online: submit the application on the ELISE portal (Singpass login) and pay the S$50 application fee (non-refundable and non-transferable) by eNETS or PayNow.
3. Take the written assessment: EMA notifies the candidate of the earliest available slot; dates can be changed via the ELISE dashboard.
4. Take the practical test and interview: usually in the same session after passing the written test.
5. Pay the licence fee: S$30 via ELISE after passing all assessments.
6. Receive the licence card by registered post within 7 working days. (A replacement card costs S$21.80 including GST.)

7. How to Use This Guide

Each chapter of this guide maps onto the official written-test syllabus: Chapter 1 covers syllabus part (a) (the Act and Regulations — the decisive Section E); Chapters 2 and 3 cover domestic and industrial installation practice; Chapter 4 builds the AC/DC and power-theory foundation assumed by the design chapters; Chapters 5–8 cover shock protection and earthing, SLDs and design calculations, testing and commissioning, and SS 650 temporary installations. Work through the sections in order, attempt every embedded quiz, and rehearse the calculations — Section B and D long questions demand worked numerical answers, not recognition.
