AS NZS 3003 – 2018 Edition – Electrical installations – Patient areas

AS NZS 3003 sets out the requirements for areas in new electrical installations and for alterations and repairs of patient areas in existing electricalinstallations where the organization/entity responsible for that electrical installation has determined that low-voltage medical electrical equipment will be used on a patient. AS NZS 3003 covers special patient areas, including homecare installations and transportable vehicles. It also contains requirements for identification, inspection and testing of patient areas.

Electrical installations in patientareas shall be carried outin accordance with AS NZS 3000, except as varied herein, and with the additional requirements of this Standard.

The decisions made by the responsible organization/entity in determining classification of patient areas need to be based on the medical procedures undertaken in each area. Advice on whether particular patient areas should be wired as body-protected or cardiac-protected electrical areas is specified in AS/NZS 2500. The responsible organization/entity should refer to the safe practice code in AS/NZS 2500 for advice on how these decisions should be based on the type of procedures undertaken in each area and thelevel of protection against electric shock afforded in the medical electrical equipment available for these procedures.

While this Standard is intended to apply to new installations or extensions, some guidance is given concerning conversion of older installations.

Areas other than patient areas are not covered by this Standard, but are covered by the relevant requirements of AS/NZS 3000.

Requirements for emergency lighting are given in AS/NZS 2293.1.
