1Under the Electricity Ordinance, Grade A electrical work covers which fixed electrical installations?

A.Low voltage with maximum demand not exceeding 2,500 A

B.Low voltage with maximum demand not exceeding 400 A, single or three phase

C.Any capacity of low-voltage fixed installation

D.High-voltage installations only

Explanation: EMSD grading defines Grade A as electrical work on that part of a low-voltage fixed electrical installation with maximum demand not exceeding 400 A, single or three phase. Grade B extends to 2,500 A and Grade C covers any LV capacity.

2Which installations are specifically excluded from Grade A electrical work scope?

A.All three-phase motor circuits

B.Neon sign installation and unvented electric thermal storage type water heater installation

C.Ceiling fan and fluorescent lighting circuits only

D.Temporary construction-site supplies

Explanation: Official Grade A scope excludes neon sign installation and unvented electric thermal storage type water heater installation. Those require Grade R (special) registration categories.

3Who is the enforcing authority for the Electricity Ordinance (Cap. 406) in Hong Kong?

A.Electrical and Mechanical Services Department (EMSD)

B.Construction Industry Council (CIC) only

C.Buildings Department alone

D.Hong Kong Examinations and Assessment Authority

Explanation: EMSD enforces Cap. 406 and its subsidiary regulations covering electrical workers, contractors, wiring, products and supply safety. CIC administers the Grade A trade test pathway but does not replace EMSD registration.

4What is EMSD Form WR1 used for?

A.Renewing a CIC trade-test certificate

B.Certifying completion of electrical work on a fixed electrical installation

C.Recording only high-voltage switching schedules

D.Applying for a construction Green Card

Explanation: Form WR1 is the Work Completion Certificate. After electrical work on a fixed installation, the responsible registered electrical worker certifies compliance and the registered electrical contractor endorses it.

5Which statement about Form WR1 practice is incorrect?

A.It shall be signed by the registered electrical worker(s) responsible for the work

B.The corresponding REC should properly keep the certificate for the required retention period

C.It shall be endorsed by the corresponding registered electrical contractor(s)

D.The installation may be first certified only after it has already been energized for unrestricted use without prior certification

Explanation: WR1 certification confirms completed work meets Wiring Regulations requirements for safe use. Claiming first certification only after unrestricted energization without proper certification is the incorrect statement; REW signature, REC endorsement and retention remain valid requirements.

6The Code of Practice for the Electricity (Wiring) Regulations is issued by:

A.Labour Department as a Factories Ordinance schedule

B.IEC as the sole Hong Kong statute

C.CLP Power as mandatory Supply Rules only

D.EMSD to give technical guidance for complying with the Electricity (Wiring) Regulations

Explanation: EMSD publishes the CoP for the Electricity (Wiring) Regulations as the primary technical guide for fixed electrical installations in Hong Kong. Power company Supply Rules are separate and complementary.

7A CIC Trade Test Certificate for Grade A Electrical Work:

A.Automatically registers the holder as Grade A REW without further application

B.Replaces the need for a Registered Electrical Contractor on any job

C.Allows unsupervised Grade H high-voltage work

D.Is not itself an EMSD Registered Electrical Worker certificate

Explanation: CIC’s introductory booklet states the trade-test certificate is not equivalent to EMSD REW registration. Holders still apply to EMSD with the certificate plus required qualifications and experience.

8Under Cap. 406 registration, electrical work on fixed installations must generally be carried out by:

A.A registered electrical worker of the appropriate grade, under a registered electrical contractor (or as otherwise permitted)

B.Any construction worker with a Green Card

C.An unregistered helper supervised only by a plumber

D.A building owner with no electrical registration

Explanation: The Electricity Ordinance requires appropriate-grade REWs and RECs for fixed electrical installation work, subject to limited exemptions. Green Card alone does not authorise electrical work.

9What is the maximum demand limit associated with Grade B electrical work on LV fixed installations?

A.Not exceeding 400 A

B.Unlimited high voltage only

C.Not exceeding 100 A

D.Not exceeding 2,500 A, single or three phase

Explanation: Grade B covers LV fixed installations with maximum demand not exceeding 2,500 A. Grade A stops at 400 A; Grade C covers any LV capacity.

10Periodic inspection and testing of fixed electrical installations is typically certified on which EMSD form family?

A.Form BC for medical fitness

B.Form WR2 (periodic test certificate)

C.A CIC practical score sheet

D.Form WR1 only, for all future years

Explanation: WR1 is for work completion; WR2 (and related variants) is used for periodic testing certification of fixed electrical installations under the regulatory framework.

About the CIC Grade A Electrical Trade Test Exam

The CIC Trade Test for Grade A Electrical Work assesses craft skill and safe-work knowledge for low-voltage fixed electrical installations with approved loading not exceeding 400 A (single or three phase), matching the EMSD Grade A Registered Electrical Worker scope. Passing the written and practical parts yields a CIC Trade Test Certificate that, together with the required qualifications and experience, can support an EMSD Grade A REW registration application. The certificate itself is not an EMSD registration.

Exam sponsor: Hong Kong Construction Industry Trade Testing Centre (HKCITTC), Construction Industry Council (CIC). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

CIC Grade A Electrical Trade Test: Suggested Study Strategy

1Memorise Unit 1 Cap. 406 / CoP items first — you need ≥70% on those 20 legislation questions, a higher bar than Unit 2's 60%.

2Drill the new conductor colour code (brown/black/grey phases, blue neutral, green-and-yellow CPC) until automatic; failing the wire colour identification test fails the entire written paper.

3Practise insulation resistance, continuity, earth-fault loop impedance and RCD meter use with correct Form WR1 recording, because the practical assigns completion testing, fault finding and WR1 as a full scored task.

Frequently Asked Questions

What is the CIC Trade Test for Grade A Electrical Work?

It is a written and practical trade test run by the Hong Kong Construction Industry Trade Testing Centre under the CIC. It assesses skills and safe-work knowledge for low-voltage fixed electrical installations with approved loading not exceeding 400 A. A pass certificate, with the required experience and qualifications, can support an EMSD Grade A Registered Electrical Worker application, but the CIC certificate is not itself an EMSD registration.

How is the written test structured and what score do I need?

The written technical knowledge test has 100 multiple-choice questions in 75 minutes: Unit 1 Legislation & Codes of Practice (20 questions, need ≥70% correct) and Unit 2 Craft, Safety & Ethics (80 questions, need ≥60% correct). You must also pass a wire colour identification test; failing colour ID fails the whole written paper. You must pass written before booking the practical.

What does the practical test involve?

In about 6 hours you complete four designated tasks covering fixed installation work (conduit bending, 13A socket radial or ring wiring, lighting or related circuits), completion testing with Form WR1 plus remote fault finding and simulated three-phase motor winding connections, cable coupler wiring, and three-phase motor control-panel wiring (forward/reverse or star-delta). Each task needs ≥60/100, average ≥75/100, key criteria met, and a safety pass (≥6/10).

How much does the CIC Grade A trade test cost?

The CIC application form revised August 2025 lists HK$100 for the written test (ELW) and HK$400 for the practical test (ELA). CIC may revise fees without prior notice. Holders of employment or student visas pay three times the basic fee.
