Electricity system maintenance: prevention over rehabilitation

The regular maintenance of fixed-power installations would help to ensure the reliability of the electricity supply, prevent electrical accidents and protect the property industry; for example, if the electrical installations were not properly maintained, subsequent maintenance costs may be higher than regular maintenance, and owners may be subject to third-party claims.Electricity system maintenanceThe organization regularly screens cable houses and public power installations and detects early exposures such as barr fever, piece ageing and infiltration.

WR2 Electricity Inspection: Fixed-term examination of electrical installations and five-year electric examination

WR2 is a tabular number under the Electricity (Travel) Ordinance. The owner of a fixed power facility, including individual unit owners, property management companies and Owners’ Corporation, has a responsibility to arrange regular inspections and tests.

At least every five years

Fixed electrical installations in ordinary buildings with an approved loading exceeding 100 amperes, or in factories and industrial undertakings exceeding 200 amperes, must be inspected, tested and certified at least every five years. Premises such as hotels, hospitals, schools and childcare centres require inspection every five years regardless of loading.

Annual inspection

Public entertainment sites, places where dangerous goods are manufactured or stored, and fixed-pressure power installations are subject to an annual check and test.

Scope of inspection

All fixed cables and associated electrical equipment, including main cables (main switchboard), electrical rising mains routes, electrical appliances, final electrical circuits and fixed electrical equipment, shall be subject to regular inspection and testing.

Statutory time limits and additional signatures

The registered electrical contractor must issue WR2 within one month of completing testing. The owner must submit it to the Electrical and Mechanical Services Department for endorsement within two weeks of issue. The endorsement fee is HK$695 per application; the contractor may be asked to submit it on the owner’s behalf.

Electric rising mains replacement work

Electrical rising mains is the building main switchboard, which runs vertically across all floors and provides electricity to each branch of the cable and household unit. The electrical rising mains in many of the old Hong Kong buildings have been used for several decades, with insulation, receptacle oxidation, combined with household refrigeration and electrical appliances that are much more than designed in the current year.

When are electrical rising mains to be replaced?

  • WR2 Electricity Inspection Report listed electrical rising mains deficiencies
  • building Frequent or wholesale, irritation
  • Receptive heat, with burns or variants
  • Households ' applications for increased electricity supply restrictions
  • Infiltration of water by cable or pipe

III. Electric rising mains design requirements

The Code of Practice of Electrical and Mechanical Services Department ' s Electricity (Travel) Regulations stipulates that any building above four layers of high (including underground) shall be equipped with three different electrical rising mains and each layer with a three-phase four-line branch. Yat is fully in the design, with the consent of the supplier.Electric rising mains replacementThe programme will recalculate the power load of the building and reserve future power growth space.

Engineering processes

Site survey → load calculations and design → itemised quotation → procurement by the Owners’ Corporation → coordination of power shutdowns with the power company and residents → phased construction → inspection, testing and issue of WR1 → restoration of power. Yat Full has replaced both the electrical rising mains and main switchboards in more than 70 buildings. For project photographs, seeElectricity Systems Engineering case。

Building main switchboard replacement and electrical cable maintenance

The building main switchboard (also known as cables, main cables) is located in the cable house, which is the general switch and protection unit after the power company is to distribute electricity to electrical rising mains, elevators, water pumps and public lighting. The main switchboard will be built together, once the fault is passed, and the building will be suspended at the same time.

Main switchboard Common issues

  • Flood water leakage of cables is corroded by tide in parts of the cables
  • Old invalidity of breakers or protective devices
  • Mother ' s line and corroboration loose hot
  • Shortcomings due to insufficient capacity
  • spare parts, which are difficult to repair
