WR2 Periodic Inspections of
Electrical Installations

Buildings owners in Hong Kong with an approved loading exceeding 100 Amp (single or three phase) electricity supply are required by law[1] to undertake a periodic inspection and testing of the electrical installation every five years, and obtain a certificate. This process is more commonly known simply as WR2 (and WR2A).

Why do I need a WR2 inspection?

Holding a valid Form WR2 is mandatory government requirement, furthermore it is good practice to have a regular check-up.

You wouldn't run a car for five years without a tune up would you? No, it makes sense to have a regular checking to ensure everything is working right.

WR2 periodic inspection covers electrical systems not subject to regular scrutiny

Furthermore the WR2 periodic inspection covers the common areas, not subject to regular scrutiny. In the past electrical installation serving corridor lighting, lifts systems, and water systems have failed causing distress and disruption for the occupants.
