20200810 SGS Registered by EMSD for Fixed Electrical Installations Periodic Tests

The Electricity Ordinance (Cap. 406) (EO) and its subsidiary regulations set out a legal framework to regulate electrical safety in Hong Kong. To ensure electrical safety of the public and building users, the Electricity (Wiring) Regulations made under the EO require that owner of electrical installation in general buildings with approved loading exceeding 100A shall arrange a registered electrical contractor/worker (REC/REW) to install, then inspect, test and certify the installation safe at least once every 5 years.

Upon the installation of a fixed electrical system, it must be inspected, tested and certified to confirm that the requirements of Electricity Ordinance have been met. A Work Completion Certificate (WR1) will be granted.

A periodic inspection will:

• Reveal if any of your electrical circuits or accessories are overloaded;
• Find any potential electric shock risks and fire hazards;
• Identify any defective electrical work;
• Highlight any lack of earthing or bonding

Safety tests are carried out on wiring and fixed electrical accessories. A schedule of circuits is also provided, which is invaluable for a property. After inspection, testing and repair, the registered electrical contractor and worker shall issue a Periodic Test Certificate to confirm that the electrical installation is safe and complies with the statutory safety requirements. The owners of the electrical installation shall submit the Periodic Test Certificate (WR2) to EMSD for endorsement. After that, they should properly retain the certificate for future inspection by EMSD.

Owner of electrical installation include individual unit owners, landlords, occupiers, tenants, incorporated owners and property management agents of businesses such as:

• Public areas of entertainment (e.g. theatres, karaoke, etc.); at least once every year
