1What is the main purpose of Personal Protective Equipment (PPE) such as safety shoes and insulated gloves for a wireman carrying out domestic wiring work?
A.To protect the wireman from electric shock, cuts and other physical hazards while working
B.To make the wireman look professional to the client
C.To speed up the wiring installation process
D.To comply with a fashion requirement of the trade
Explanation: PPE such as safety shoes, insulated gloves and a safety helmet protects the wireman from electric shock, falls, cuts and other hazards on site. The Electricity Regulations 1994 safety requirements specify suitable personal protection equipment as a basic safe-work practice.
2Before carrying out any maintenance or testing work on an existing domestic wiring circuit, what must a wireman do first?
A.Increase the circuit's protective device rating
B.Switch off and isolate the electricity supply to the circuit
C.Inform the neighbours about the work
D.Replace all sockets in the house
Explanation: Undertaking electrical work without disconnecting the supply is a leading cause of unsafe conditions that result in electric shocks. A wireman must always isolate the supply before maintenance, testing or repair work begins.
3Under Regulation 11(1) of the Electricity Regulations 1994, wiring or rewiring of an installation, or an extension to an existing installation, must be carried out by whom, with prior written approval obtained from a licensee or supply authority?
A.Any homeowner who purchases the wiring materials
B.An Electrical Contractor or a Private Wiring Unit (PWU)
C.A general building contractor
D.The Tenaga Nasional Berhad billing department
Explanation: Regulation 11(1) requires wiring, rewiring, or extension work to be carried out by an Electrical Contractor or a Private Wiring Unit registered with the Energy Commission, with written approval obtained from the licensee or supply authority beforehand.
4A wireman receives an electric shock after touching the metal casing of a washing machine that has a leaking phase conductor inside, without ever touching a bare live wire. What type of electrical contact caused this shock?
A.Direct contact
B.Indirect contact
C.Capacitive contact
D.Thermal contact
Explanation: Indirect contact occurs when a person touches a part connected to the installation, such as an appliance frame, that has become live due to a fault or insulation failure, rather than touching a live conductor directly.
5Under the Electricity Regulations 1994, who is legally permitted to carry out or directly supervise electrical wiring work in a residential building?
A.Any adult resident of the house
B.A licensed plumber
C.A competent person registered with Suruhanjaya Tenaga (the Energy Commission)
D.A hardware store salesperson
Explanation: The Electricity Regulations 1994 require electrical work to be carried out by, or under the direct supervision of, a competent person registered with Suruhanjaya Tenaga, and the electrical contractor undertaking the work must also be registered.
6As a general safety requirement for using portable electrical equipment at a wiring work site, the supply to that equipment should be provided through a residual current device (RCD) with what maximum sensitivity?
A.10 mA
B.30 mA
C.100 mA
D.300 mA
Explanation: The safety requirements for electrical wiring works state that electrical equipment used at the work place should be supplied through an RCD with a sensitivity of 30 mA to protect workers from earth leakage shocks.
7What fire-safety equipment must be available at an electrical wiring work place at all times, according to the safety requirements for electrical wiring works?
A.A sand bucket only
B.A suitable, functioning fire extinguisher
C.A smoke detector connected to the fire brigade
D.A water hose reel
Explanation: The safety requirements state that a suitable, functioning fire extinguisher to control fires must be made available at the work place at all times.
8What is the purpose of first aid given to a worker who has suffered an electrical shock at a wiring work site?
A.To fully cure the worker without needing further medical treatment
B.To provide initial assistance and prevent the condition from worsening while awaiting medical help
C.To restore electricity supply to the circuit
D.To replace the damaged wiring immediately
Explanation: First aid is the initial assistance given to an injured person to prevent their condition from becoming more serious while awaiting the arrival of paramedics or before being taken to hospital; it is not a substitute for proper medical treatment.
9Under Regulation 36(1) of the Electricity Regulations 1994, what is the maximum RCD sensitivity required for earth leakage protection at a place of public entertainment?
A.100 milliamperes
B.30 milliamperes
C.10 milliamperes
D.300 milliamperes
Explanation: Regulation 36(1) requires protection against earth leakage current at a place of public entertainment to be provided by an RCD of sensitivity not exceeding 10 milliamperes.
10Regulation 36(2) of the Electricity Regulations 1994 requires an RCD of what maximum sensitivity where the floor is likely to be wet or the wall/enclosure has low electrical resistance?
A.10 milliamperes
B.30 milliamperes
C.100 milliamperes
D.500 milliamperes
Explanation: Regulation 36(2) sets the same 10 mA maximum sensitivity requirement for wet-floor locations or low-resistance walls and enclosures as it does for places of public entertainment.

About the SPM Pendawaian Domestik Exam

SPM Pendawaian Domestik (subject code 7104) is a KSSM Mata Pelajaran Vokasional (MPV) elective sat at the end of Form 5. The official written paper 7104/1 appears on the Ministry of Education Malaysia SPM 2025 timetable and lasts 2 hours. Assessment combines a Malay-language written Kertas 1 (Bahagian A: 15 short-structured-response questions worth 60 marks; Bahagian B: 4 extended-response questions worth 40 marks; total 100 marks; weighted 40% of the subject grade) with Kertas 2 school-based practical coursework (PBS) across 8 assessment modules run from February of Form 4 to July of Form 5, weighted 60%.

SPM Pendawaian Domestik Study Tips from Top Performers

1Learn the difference between a radial final circuit and a ring final circuit for socket outlets, and which minimum conductor size and protective-device rating each requires under Suruhanjaya Tenaga's guideline.
2Memorise fixed-wiring conductor colours (single-phase live: red, yellow or blue; neutral: black; earth/protective: green or green-yellow) and keep them separate from flexible-cord colours.
3Practise the correct sequence of dead tests before energising a circuit: continuity test first, then insulation resistance test, then polarity test.
4Know the earth electrode resistance test setup: the potential spike is placed about 10 m from the electrode and the current spike about 20 m away, with the test repeated at least three times.
5Compare PVC conduit, metal conduit, trunking and concealed wiring by the mechanical and fire protection each gives a cable, not just by appearance.
6Tie every wiring decision back to workshop and electrical safety (OM1); Kertas 1 rewards correct safe-practice recall as heavily as pure technical knowledge.
7Remember Kertas 1 is written (not MCQ) and weighted only 40% of the final grade; strong performance still requires completing all 8 PBS coursework modules.
