Updated standard: AS/NZS 3003:2018 Electrical installations ā€“ 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 2.4.3.1.2.
  • The distance required for socket-outlets within the entrance to a body-protected electrical area has been reduced to 2.0 m.
  • Access to RCD controls and indicators is clarified in Table 2.1.
  • Additional requirements have been included for socket-outlet labelling.
  • Additional requirements have been included for socket-outlets requiring isolation switches.
  • Additional requirements have been included for identification of socket-outlets protected by LPDs.
  • Equipotential earthing terminals have been clarified.
  • Equipotential earthing system requirements for nodes connected to the EP junction are now reflected in Figure 8.
  • 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 6.2.5.3.
  • 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.
  • Section 7 is now ‘Identification of patient areas’.
  • Section 8 is now ‘Routine inspection and testing of cardiac and body-protected electrical areas’.
  • Provisions for magnetic fields are now informative and located in Appendix H.
  • Revised guidance tables have been included to illustrate requirements.
