Updated standard: AS/NZS 3003:2018 Electrical installations – Patient areas
This recently updated standard specifies special requirements for electrical installations in patient areas. These requirements are additional to those specified in AS/NZS 3000.
AS/NZS 3003:2018 is now available to view on TKB by NECA WA members. (NB: AS/NZS 3003:2011 will remain available on TKB for the next 6 months for reference.)
Major changes in this edition include the following:
- The decisions made by the responsible organization/entity in determining patient areas need to be based on the classification of the medical procedures undertaken in each area.
- The word ‘point’ has been defined.
- The term ‘Responsible organization/entity’ has been defined.
- The term ‘electrical equipment’ has replaced the term ‘appliance’.
- The word ‘identification’ has replaced the word ‘marking’.
- The word ‘confirm’ has replaced the words ‘verified’ and ‘checked’.
- The term ‘testing and verification’ has replaced the term ‘testing and commissioning’.
- Exceptions have been included throughout this Standard.
- The responsible organization/entity is required to provide documentation outlining patient area locations and classifications.
- Patient area boundaries have been clarified in Figure 4.
- The patient areas, as determined by the responsible organization/entity, in any facility, building, institution or medical practice not wired as cardiac-protected electrical areas are required to be wired as body-protected electrical areas.
- Separation of circuits in cardiac-protected electrical areas has been clarified.
- A clause on extra-low-voltage charging sockets (including USB) has been added, see Clause 220.127.116.11.2.
- The distance required for socket-outlets within the entrance to a body-protected electrical area has been reduced to 2.0 m.

- EP test terminals have been clarified.
- EP conductor labelling has been clarified.
- Where fixed electrical equipment rated at or above 2.0 kW is to be installed in a body-protected or cardiac-protected electrical area, the entire patient area is required to conform with this Standard.
- A clause on disability and aged care has been added, see Clause 5.3.
- A clause on reclassification of existing cardiac-protected electrical areas as body-protected electrical areas has been added, see Clause 18.104.22.168.
- Repairs within patient areas not wired as cardiac-protected or body-protected electrical areas in most cases will trigger upgrading to be in accordance with this Standard.
- An identification clause on alterations and additions within a patient area has been added, see Clause 6.2.5.
