On-Site Fixed Electrical Installations (WR2) Test



On-Site Fixed Electrical Installations (WR2) Test

Service Scope

The Electricity Ordinance (Cap. 406) (EO) and its subsidiary regulations set out a legal framework to regulate electrical safety in Hong Kong. To ensure the electrical safety of the public and building users, the Electricity (Wiring) Regulations made under the EO require that owner of the 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.

As an authorized contractor for EMSD, we can carry out safety tests on wiring and fixed electrical accessories on your commercial property.  After inspection, testing, and repair, SGS will issue a Periodic Test Certificate (WR2) to confirm that the electrical installation is safe and complies with the statutory safety requirements. The owner will then require to submit this certificate to EMSD for endorsement.
