Ceiling Insulation Wiring Rules

Wiring Rules Clause Recessed Luminairies (recessed ceiling lights)

Under National Building Code requirements, bulk thermal insulation is prevalent in modern buildings; within roof voids & placed above & on the ceiling sheets, within walls and floors; insulation coverage may vary depending on the type of building and its climate zone.

Bulk thermal insulation may also be retrofitted to an existing building, added or altered in which case precautions will need to be applied by the insulation installer, where recessed downlights are present, or the luminaire installer, where insulation is present.

In Australia AS 3999 provides instructions for insulation installers in relation to clearances from recessed downlights and other types of electrical equipment that may be adversely affected by lack of surrounding air circulation for cooling.
