Electrical Services Section 20.00 / Page 18
Cables shall not be installed within the ceiling space of the floor below that it is to service, except
for between the Main Switchroom and the electrical services riser. Cables shall not be installed
in floor slabs unless approved by the Superintendent.
20.10.08 Cable Penetrations
All cable penetrations shall be reinstated to original rating of the penetrated barrier (fire, acoustic,
moisture).
20.11 Special Requirements for Laboratories (Wet or Dry)
20.11. 01 Distribution Boards
Each Laboratory shall have its own distribution board complete with surge arrestor.
20.11.02 Safety Isolators
Provide the relevant safety isolators for power, gas and other services as required by the
relevant standards and regulations. Isolators shall be ‘NHP D5’ range or approved equal, colour
coded or super bright. Position isolators adjacent to doors and away from light switches if
possible. Isolators shall be shrouded to prevent accidental activation.
If loss off service supply occurs, reinstatement shall be achieved via a padlocked remote reset
button flush mounted on the door of the laboratory distribution board, complete with an engraved
traffolyte label (red on white) to read ‘Emergency Stop Reset Button, Operation by Authorised
Person Only’. Automatic reinstatement of the service on resumption of supply to an area will only
be provided when required by the project Technical Brief.
20.11.03 Laboratory Services
Socket outlets in wet laboratories are usually placed on a service spine above the bench top and
away from potential hazard. In many cases, the location and separation of the services is
determined by regulation. Services and controls shall be located in positions accessible to users
particularly where the workstations have been designed to accommodate people with disabilities.
The classification of any hazardous area within a laboratory shall be confirmed with the Users
through OFM. The Electrical design for any hazardous areas shall comply with the requirements
of AS 2381.
Refer to Clause 20.07.11 of this Section for power supply requirements for specialized
laboratory equipment.
20.11.04 Patient Care Areas
Where an area is classified as a ‘Patient Care Area’, the electrical wiring shall comply with the
requirements of AS/NZS 3003.
The need to wire patient areas as a ‘Body Protected’ or ‘Cardiac Protected’ area shall be
determined by reference to AS/NZS 2500. RCDs used in these areas shall be Type 1.
20.12 Emergency Evacuation Lighting
20.12.01 Emergency Lighting System
No centralised stand-by generator/alternator facilities exist on GU campuses.
The emergency lighting system shall be designed and installed to the requirements of the BCA
and AS 2293. A single-point self-contained system with a computerised testing and monitoring
system shall be used. Each luminaire shall come complete with its own battery, charger, mains
failure relay, dc/ac inverter (in case of fluorescent type) and microcontroller-based
communications/monitoring circuit. The whole lighting system shall be monitored and controlled
by a master controller via a communication network and necessary software.
