A.A fine, imprisonment for up to two years, or both

B.A verbal warning and a small administrative fee of GH¢50

C.Permanent confiscation of all electrical tools and safety equipment

D.Disqualification from ever applying for technical courses in Ghana

Explanation: Under L.I. 2008, undertaking electrical wiring without certification is a criminal offense. Offenders are liable upon summary conviction to a fine, imprisonment for a term not exceeding two years, or both, to deter unsafe and substandard wiring practices.

6All electrical materials and equipment used for wiring installations in Ghana must comply with standards established by which authority?

A.Ghana Standards Authority (GSA)

B.Environmental Protection Agency (EPA)

C.Ghana Institution of Engineering (GhIE)

D.Public Utilities Regulatory Commission (PURC)

Explanation: The Ghana Standards Authority (GSA) is the national standards body responsible for testing and certifying that materials (like cables, conduits, and accessories) meet quality and safety benchmarks before they can be used in wiring installations.

7According to L.I. 2008, who must co-sign the Form A certificate alongside the Certified Electrical Wiring Professional (CEWP) who did the installation?

A.The Certified Electrical Wiring Inspector (CEWI)

B.The CEO of the utility company

C.The local building planning officer

D.A representative from the Ghana Standards Authority

Explanation: The regulations require that the Completed Form A must be co-signed/endorsed by a Certified Electrical Wiring Inspector (CEWI) after an independent inspection has verified that the installation complies with all safety codes before utility connection.

8Under the Ghana Electrical Wiring Regulations, after how many years must a domestic electrical installation undergo periodic testing and inspection?

A.10 years

B.5 years

C.15 years

D.20 years

Explanation: Domestic installations must be inspected and tested every 10 years to verify that the wiring, insulation, and protective devices are still in safe operating condition, preventing potential electrical fires or shock hazards as the building ages.

9What is the minimum age requirement for an applicant to be eligible for certification as an electrical wiring professional in Ghana?

A.18 years

B.16 years

C.21 years

D.25 years

Explanation: To be legally registered and certified by the Energy Commission of Ghana as a CEWP, the candidate must be at least 18 years old and possess the necessary technical qualifications or practical apprenticeship background.

10What is the legal consequence for a public utility company (like ECG) if it connects power to a new installation without a valid Form A certificate?

A.The utility is liable to a fine or sanctions by the Energy Commission

B.The utility is permanently closed down by the government

C.The individual technician is promoted for fast service delivery

D.No penalty is applied as utility companies are exempt from L.I. 2008

Explanation: L.I. 2008 imposes strict penalties on utility providers as well. If a utility connects an installation without a valid Form A signed by a CEWP and CEWI, it is committing an offense and faces administrative fines or regulatory sanctions from the Energy Commission.
