Bulk thermal insulation covering electrical wiring and equipment

A number of concerns have been raised regarding thermal insulation covering electrical equipment and in particular down lights which have been installed in ceilings.

The temperature rise effect on down lights fully covered by bulk thermal insulation can result in a fire.

Electrical Contractors

The Australian/New Zealand Standard AS/NZS 3000:2000 : Electrical installations (Wiring rules), clause 4.3.6.3 sets out a requirement for the installation of down lights near bulk thermal insulation and, in particular, the requirement of providing separation.

Electrical contractors are required to install barriers around down lights regardless if bulk thermal insulation is installed in the ceiling space.

Insulation Installers

As an installer of thermal insulation you should be familiar with the AS 3999: Thermal insulation of dwellings - Bulk insulation - Installation requirements. Clause 2.6 also sets out the requirements for bulk thermal insulation near electrical wiring and equipment.

Please remind your employees that when installing bulk thermal insulation that they take necessary precautions to prevent down lights being covered.
