Electrical installations in ceiling spaces
It is important that electrical contractors and electrical workers ensure compliance with the Wiring Rules, AS/NZS 3000 when installing electrical equipment and wiring in an accessible ceiling space.
Unprotected and poorly placed electric cables can easily be damaged by people entering a ceiling space. Home occupiers and workers installing plumbing, telephone, audio, data and air conditioning services are then at risk of electric shock, either through direct contact with live parts or contact with structural metal work that has become live.
Walking on, dragging objects over, or placing objects on cable installed in a ceiling can damage cable insulation, exposing live conductors. Cables installed over structural members in locations where they are likely to be disturbed therefore require additional protection due to the higher risk of damage. In addition, electrical workers should be aware of sharp edges when installing cables around or on metallic and non-metallic building elements.
The Wiring Rules, AS/NZS 3000 outlines requirements for protection, location and support when installing cables in ceiling spaces, both solid and suspended.
The Electrical Safety Office is currently auditing electrical installations installed in ceiling spaces to ensure they are compliant with the Wiring Rules and additional mechanical protection is installed where required.
