To enhance electrical safety, EMSD requires Registered electrical contractors (RECs) and workers (REWs) to provide test data on all branch and final circuits in addition to the schematic diagrams and checklists for the submission of the Periodic Test Certificates. REC/REW can download the proposed Schedule of Test Results for the record of test data. At the same time, EMSD will increase the number of inspections to verify the given data. If an electrical installation is found not fully complying with the safety requirements, we will take appropriate action in accordance with the Electricity Ordinance.
