This Standard sets out the minimum safety requirements related to the use of generating sets for the supply of electricity at voltages normally exceeding 50 V a.c. or 120 V d.c.The Standard applies to electricity generating sets that are driven by internal combustion engines, and which are used for the supply of electrical installations in buildings or items of electrical equipment.This Standard does not -(a) set out performance and constructional requirements for generating sets; or(b) specifically apply to specialized automatic sources of supply, e.g. no break systems or generating sets operated by Electricity Generating entities or Electricity Distributors; or (c) apply to uninterruptible power supplies; or(d) apply to other generation systems; such as: (i) Inverters.(ii) Photovoltaic arrays.(iii) Water or wind driven.While not intended to be applied to other than generating sets driven by internal combustion engines, the electrical principles could be applied to generating sets with other types of energy sources. Requirements for the performance and construction of transportable generating sets up to 25 kW are given in AS 2790.Requirements for the design, installation and operation of emergency power supplies in hospitals are given in AS/NZS 3009.Requirements for the design, installation and operation of uninterruptible power supplies are given in the AS 62040 series of Standards.Attention is drawn to the fact that some Regulatory Authorities have requirements for limitation of noise levels and pollution emissions.
