This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee EL-002 - Safety of Household and Similar Electrical Appliances and Small Power Transformers to supersede AS/NZS 4763 (Int):2006 and its amendments from the date of its publication.
The objective of this Standard is to provide manufacturers, designers, regulatory authorities, testing laboratories and similar organizations with safety requirements designed to give the user protection against hazards that might occur during normal operation and abnormal operation of an inverter and which may be used as the basis for approval for sale in Australia and New Zealand.
In converting the Interim edition of this Standard to a full joint Australia/New Zealand Standard, the opportunity has be taken update the normative references.
The essential safety requirements in AS/NZS 3820 that could be applicable to portable inverters have been taken into account in the drafting of this Standard. Furthermore, it has been assumed that the execution of its provisions is entrusted to appropriately qualified and experienced persons.
The term 'normative' has been used in this Standard to define the application of the appendix to which it applies. A 'normative' appendix is an integral part of this Standard.
Reconfirmed: 2024-02-23 Originated as AS/NZS 4763(Int):2006. Jointly re-designated AS/NZS 4763:2011.
