Provides requirements and guidance for the design of stand-alone power systems with energy storage at extra-low voltage and used for the supply of extra-low and/or low voltage electric power in a domestic situation.

Specifies requirements for general installation and safety requirements for battery energy storage systems (BESSs), where the battery system is installed in a location, such as a dedicated enclosure or room, and is connected with power conversion equipment (PCE) to supply electric power to other parts of an electrical installation.

Sets out safety and installation requirements for stand-alone power systems used for the supply of extra-low (ELV) and/or low voltage (LV) electric power to a single load, or an electrical installation in a single residence or building, or a group of residences or buildings and associated items with switchboards to AS/NZS 3000 requirements.

Sets out general installation and safety requirements for electrical installations of PV arrays, including d.c. array wiring, electrical protection devices, switching and earthing provisions.

Specifies the electrical and general safety installation requirements for inverter energy systems (IES) up to or equal to 200kVA for the injection of electric power to an electrical installation connected to the grid at low voltage.

AS NZS 3000 2018 (known as the Australian/New Zealand Wiring Rules) specifies requirements for the design, construction and verification of electrical installations, including the selection and installation of electrical equipment forming part of such electrical installations; part 1 provides provisions that constitute the minimum regulatory requirements for a safe electrical installation; part 2 provides work methods and installation practices that are ‘deemed to comply’ with the requirements of Part 1.

NATSPEC worksections cover a wide range of chillers including those with centrifugal, screw or scroll compressors, air or water cooling and heat recovery. Absorption chillers are also included; the chiller worksections also include options for specifying requirements such as IPLV and NPLV; this TECHnote aims to help specifiers to complete the included schedules.

Discusses options for specifying particulate air filters for air conditioning and ventilation.

NATSPEC produces a range of specification worksection templates which include technical and quality requirements for most building types.

Develop simple and flexible guiding principles that work within the context of the practice.
