1Under the Professional Engineers Act, a person who is not a registered Professional Engineer but uses the title 'Professional Engineer' (or otherwise holds themselves out as one) is guilty of an offence. What is the penalty for a first-time individual offender?
A.A fine not exceeding S$1,000
B.A fine not exceeding S$5,000
C.A fine not exceeding S$10,000 or imprisonment for a term not exceeding 6 months, or both
D.A fine not exceeding S$2,000 or imprisonment for a term not exceeding 3 months, or both
Explanation: Under the Professional Engineers Act, any unregistered individual who misuses the protected title 'Professional Engineer' or practices professional engineering is liable on conviction to a fine not exceeding S$5,000 for a first offence. For second or subsequent offences, the penalty increases to a fine not exceeding S$10,000, imprisonment for up to 6 months, or both.
2Under the PEB's 2026 PPE examination format, how much working time is allowed for Part 1 (Common), excluding the separate reading time?
A.1 hour 40 minutes
B.2 hours 10 minutes
C.3 hours
D.4 hours 10 minutes
Explanation: The 2026 PEB examination brochure gives Part 1 (Common) 2 hours 10 minutes of working time. Candidates first answer 10 compulsory multiple-choice questions and then answer 3 of 5 essay questions.
3Under the current Code of Professional Conduct and Ethics, may a Professional Engineer endorse an engineering product in a commercial advertisement?
A.Yes, whenever the manufacturer supplies laboratory reports and the PE independently verifies every advertised performance claim.
B.No; the Code prohibits a PE from endorsing engineering products or processes in a commercial advertisement.
C.Yes, if the PE is paid only a fixed fee rather than commission.
D.Yes, if the advertisement does not display the PE's registration number.
Explanation: Part 1 paragraph 2(10) of the Code prohibits a PE from endorsing engineering products or processes in any commercial advertisement. This is separate from giving project-specific professional advice that fully reflects the PE's best judgment.
4Which statement correctly describes Part 2 (Electrical) of the PEB's 2026 Practice of Professional Engineering Examination?
A.It is a 2-hour paper consisting only of 50 compulsory multiple-choice questions.
B.It allows 4 hours 10 minutes, and all 8 questions must be answered.
C.It allows 4 hours 10 minutes, and candidates answer 5 of 8 questions.
D.It is an oral interview conducted after Part 1 on the same day.
Explanation: For the Electrical branch in 2026, Part 2 has 4 hours 10 minutes of working time and requires candidates to answer 5 of 8 questions. It is an open-book written examination separate from the Professional Interview.
5What is the current EMA approved-load limit for a Licensed Electrical Technician designing a low-voltage electrical installation?
A.They can design and submit plans for any low-voltage installation with no load limit.
B.They can design and submit plans for electrical installations not exceeding 45 kVA.
C.They can design and submit plans for electrical installations not exceeding 150 kVA.
D.They are not authorized to design or submit plans; they can only operate and maintain systems up to 500 kVA.
Explanation: EMA authorises a Licensed Electrical Technician to design electrical installations not exceeding 150 kVA at 1,000 V and below. The same licence class has a separate operation limit of 500 kVA at low voltage.
6An electrical installation has an approved load of 400 kVA at 400 V. What is the minimum Licensed Electrical Worker class authorised to be in charge of its operation?
A.Licensed Electrician
B.Licensed Electrical Technician
C.Licensed Electrical Engineer
D.Any registered Professional Engineer, even without an LEW licence
Explanation: EMA authorises a Licensed Electrical Technician to operate installations not exceeding 500 kVA at 1,000 V and below. A 400 kVA, 400 V installation is within that operation limit, whereas a Licensed Electrician cannot independently take charge at this approved load.
7For a low-voltage installation whose approved load exceeds the Licensed Electrical Technician's 150 kVA design limit, what is the minimum EMA worker-licence class authorised to design the installation?
A.Licensed Electrician
B.Licensed Electrical Engineer
C.Licensed Electrical Technician
D.A registered PE who does not hold an EMA electrical-worker licence
Explanation: EMA limits a Licensed Electrical Technician to design of installations not exceeding 150 kVA at 1,000 V and below. Above that design limit, the work requires a Licensed Electrical Engineer whose licence conditions cover it; PE registration alone is not an EMA electrical-worker licence.
8A registered Professional Engineer is found guilty of professional misconduct by a Disciplinary Committee. What is the maximum fine the Committee can impose under the Professional Engineers Act?
A.S$5,000
B.S$10,000
C.S$20,000
D.S$50,000
Explanation: Under the Professional Engineers Act, the Disciplinary Committee may order a professional engineer found guilty of improper conduct to pay a penalty (fine) not exceeding S$50,000, in addition to censuring the PE, suspending registration for up to 2 years, or striking the PE off the register. This disciplinary penalty enforces compliance with the Code of Professional Conduct, and the engineer may also be ordered to pay the costs and expenses of the inquiry.
9What reference-material policy applies to the written PPE under the PEB's 2026 examination instructions?
A.Both written parts are closed book, with only a non-programmable scientific calculator and blank paper allowed.
B.The written examination is open book, subject to the examination instructions.
C.Only an unannotated copy of the Professional Engineers Act may be used.
D.Candidates may access online standards and websites during the paper.
Explanation: The PEB describes the written PPE as open book. Open book does not imply unrestricted electronic or online access; candidates must still comply with the detailed examination instructions on permitted materials and devices.
10Which statutory authority in Singapore is responsible for issuing electrical installation licences and regulating Licensed Electrical Workers?
A.Professional Engineers Board (PEB)
B.Energy Market Authority (EMA)
C.Building and Construction Authority (BCA)
D.SP Group / SP PowerGrid
Explanation: The Energy Market Authority (EMA) is the regulatory body responsible for issuing licences to electrical workers (LEWs), electrical installations, and enforcing electrical safety regulations under the Electricity Act. The EMA plays a central role in regulating the generation, transmission, and retail supply of electricity in Singapore. It also issues safety guidelines and codes of practice to maintain grid reliability.

SG PPE Electrical: Suggested Study Strategy

1Tab and index your copies of SS 638, SS 551, SS 555, and the PE Act. Since the exam is open-book, speed in referencing specific clauses is critical.
2Master cable sizing and voltage drop calculations under Singapore's tropical ambient temperature (40°C) and derating factors.
3Be prepared for Part 1 essay questions regarding conflict of interest, signing off on designs prepared by others, and disciplinary board procedures.
4Understand Licensed Electrical Worker (LEW) licensing thresholds: Electrician (45 kVA), Technician (150 kVA design, 500 kVA operate), and Engineer (no limit).
5Practice answering design scenarios, such as sizing standby generators under SS 535 or designing earthing arrangements for a substation under SS 551.

Frequently Asked Questions

What is the format of the SG PPE Electrical exam?

The exam is open-book and divided into two parts held on the same day. Part 1 (Common Paper) is 2 hours and 10 minutes, consisting of 10 compulsory MCQs and 3 out of 5 essay questions. Part 2 (Electrical Engineering) is 4 hours and 10 minutes, requiring candidates to answer 5 out of 8 technical essay/design questions.

What are the key codes tested in the Electrical PPE?

Candidates are heavily tested on Singapore Standards, specifically: SS 638 (Code of Practice for Electrical Installations, formerly CP 5), SS 551 (Earthing, formerly CP 2), SS 555 (Protection Against Lightning, formerly CP 16), and SS 535 (Standby Generator Sets, formerly CP 31). Local electricity acts and EMA licensing requirements are also key.

Can I sit for the PPE without passing the FEE?

No. Passing the Fundamentals of Engineering Examination (FEE) in the electrical branch is a strict prerequisite. In addition, you must have acquired at least 2 years and 6 months of approved practical electrical engineering experience, primarily in Singapore, under the supervision of a registered PE.

What is the passing criteria for the PPE?

The exam is graded on a Pass/Fail basis. To pass, you must obtain a passing mark in both Part 1 and Part 2. If you fail only one part, you must retake the exam, but you can request an exemption for the passed part in future attempts for up to 3 years.
