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.

Explanation: The Professional Engineers Act and Rules state that a registered Professional Engineer must notify the Registrar in writing of any change to their registered business or residential address within 2 weeks (14 days) of the occurrence. This is a strict professional requirement to maintain registry accuracy.

Explanation: Rule 9 of the Professional Conduct and Ethics Rules requires a Professional Engineer, before undertaking a commission to review, amend, or duplicate the work of another PE, to take reasonable steps to notify the other engineer in writing of the engagement. This ensures transparency and professional courtesy.

Explanation: Under the PE Rules and Code of Ethics, a PE must not sign or seal plans, drawings, or specifications unless they were prepared by the PE or under their personal direction and supervision. If endorsing overseas designs, the PE must verify the engineering principles, check all calculations, modify the plans as necessary, and take full legal and professional responsibility as the Qualified Person (QP).

Explanation: According to the Energy Market Authority (EMA) regulations, a Licensed Electrical Technician (Grade 8) is authorized to design and submit plans for electrical installations with an approved load of up to 150 kVA. They are also authorized to install, operate, and maintain systems up to 500 kVA.

Explanation: Under the Electricity (Electrical Installations) Regulations, an installation with a load exceeding 45 kVA but not exceeding 500 kVA (at low voltage, i.e., 1,000V and below) requires at least a Licensed Electrical Technician (Grade 8) to be in charge of its operation and maintenance. This ensures that the system is managed by a worker who has the necessary qualifications for low-voltage systems up to 500 kVA. If the load exceeds 500 kVA or operates at high voltage, a Licensed Electrical Engineer is required.

Explanation: Installations with an approved load exceeding 150 kVA (or operating at high voltage) must have their electrical designs prepared and submitted to the transmission licensee (SP PowerGrid) and EMA by a Licensed Electrical Engineer (Grade 9) or a registered Professional Engineer. This requirement ensures that large-scale power distribution systems are engineered with adequate safety margins and protective coordination. Technicians are restricted to design submissions below this threshold.

Explanation: Under Section 31b of the Professional Engineers Act, the Disciplinary Committee has the power to order the professional engineer to pay a penalty (fine) not exceeding S$20,000, in addition to censuring, suspending, or striking the PE off the register. This disciplinary fine represents a civil penalty collected by the Board to enforce compliance with the Code of Professional Conduct. The engineer may also be ordered to pay the costs and expenses of the inquiry.

Explanation: The Professional Engineers Rules allow professional engineers to advertise their services as long as the advertisements are factual, dignified, and truthful. They must not contain comparative claims, boastful language, or references that could mislead the public or bring the profession into disrepute.

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.
