[Current]Electrical installations - Periodic assessment
AS/NZS 3019 sets out the requirements for periodic assessment of existing electrical installations which are connected to a low voltage a.c. supply system (exceeding 50 V a.c. but not exceeding 1 000 V a.c.). Inspection and/or testing is intended, as far as reasonably practicable, to determine whether the installation and all its constituent equipment is in a safe condition for continued use.
