Guidelines for electricity supply to lifts
To provide practical guidance on prescribed inspection and testing requirements for passenger lifts.
To ensure passenger lifts installed in commercial building structures, which are available for passenger use, are provided with electrical supply and protective devices designed for safe operation.
These guidelines apply to a lift installer, electricians, builders and building owners in control of installations where lifts are used to convey passengers
Passenger lifts used in all Victorian commercial installations are considered to be a safety service as defined in Australian/New Zealand Wiring Rules. As such they are to be installed to conform to requirements of AS/NZS 3000:2007 and AS1735.2 prior to use for conveying passengers. Often in early stages of construction passenger lifts are commissioned to be used as a lift to convey persons and materials during the remainder of the construction stage. This type of passenger lift is commonly termed as a ‘builders lift’.
Where a passenger lift is to be used as a ‘builders lift’ it must meet all requirements for the testing and commissioning to ensure performance and safety mechanisms are verified.
Passenger lifts, being a safety service, are required to have prescribed electrical installation work inspected by a licensed electrical inspector prior to the lift being placed in service. This is a requirement of Electricity Safety (Installation) Regulations 2009.
Inspection of electrical installation work
An electrician who is responsible for the carrying out of prescribed electrical installation work must ensure that the work is inspected by a licensed electrical inspector in accordance with the regulations before the electrical installation is connected to the electricity supply, or if the electrical circuits or electrical equipment handled in the course of the work were not disconnected from the electricity supply, before the work is first used after it is completed.
An electrician must ensure that the licensed electrical inspector inspecting any prescribed electrical installation work is not a person who is employed by the electrician; or a related body corporate of the electrician.
The passenger lift shall pass all requirements of the prescribed inspection before handover for use.
Recommended items to be inspected for verification
- All mains and sub mains cables from the point of supply through to the lift switchboard associated with the lift installation to ensure appropriate WS rating is provided,
- Basic protection (protection against direct contact with live parts), e.g. insulation and enclosure,
- Fault protection – protection against indirect contact with exposed conductive parts,
- Protection against hazardous parts, e.g. enclosure, guarding or screening of flammable materials, hot surfaces and parts that may cause physical injury,
- Protection against spread of fire, e.g. penetration of fire barriers,
- Motor room door installation and labelling, and
- General condition of the electrical equipment, e.g. signs of damage that could impair safe operation, disconnection of unused electrical equipment.
- Identification of cable cores
- Current carrying capacity of mains
- Voltage drop, e.g. size and length of conductors and load
- Underground installation conditions, e.g. enclosure, depth of burial, mechanical protection
- Connection of wiring
- Protection against external influences
- Location, e.g. access and egress, not in restricted location
- Protective devices, e.g. selection and setting of adjustable protective devices for
- compliance with over current protection, arc fault protection and discrimination
- Isolating devices, e.g. main switches
- Connecting devices, e.g. neutral bars, earth bars and active links
- Connection and fixing of wiring and switchgear
- Identification and labelling of electrical equipment, and
- Protection against external influences, e.g. mechanical damage
Licensed Electrical Inspector means a person holding an inspector’s licence under the Electricity Safety (Installations) Regulations 2009.
Passenger lift in this document means an electrically controlled lift that is capable of conveying passengers, but does not include a lift installed in a single private residence in accordance with AS1735.18.
Safety service has the same meaning as it has in the Australian/New Zealand Wiring Rules AS/NZS 3000:2007.
Prescribed electrical installation work, for the purposes of Electricity Safety Act 1998 section 45, prescribed electrical installation work means work on all or part of any of the following electrical installations if they are ordinarily operated at low voltage or a voltage exceeding low voltage— circuit protective devices, switchgear, control gear, wiring systems and accessories (other than fire detection and alarm systems) installed to provide control and protection of passenger lifts.
Verification means all measures by means of which compliance of the electrical installation with the relevant requirements of AS/NZS 3000 and AS/NZS3017:2000 is checked.
