New installations, additions or alterations of electrical installations should comply with the safety requirements of the Electricity Ordinance. Before carrying out any addition or alteration : -

Owners should ensure that the power loading generated by the appliances and installations do not exceed the maximum loading approved by the electricity supply company. Qualified building services engineer or registered electrical contractor should be consulted if in doubt. Electrical installations with an approved loading exceeding 100 amperes (A) in residential apartments, shops, offices and communal areas of the building should be inspected, tested and certified (Form WR2) at least once every 5 years to ensure safety.
