Is the Transformer Isolator Accessory required by the new Standard AS/NZS 3000:2007 clause 4.5.2.3?
The Standard requires that the auxiliary equipment of a luminaire must be installed in a manner designed to prevent the risk of fire. The thermal cut-out feature of transformers is designed to function if it overheats, often called “cycling” when downlights turn off regularly. While this feature is a vital safe guard, it is no excuse for the poor ventilation of transformers, which can also annoy contractors with needless call-outs from unsatisfied clients. It should not be relied on because the thermal cut-out function has been known to fail and actually cause fires, particularly when the transformer is mounted on combustible materials. Transformer installations tend to clutter ceilings and create “kick” or “trip” hazards. The Transformer Isololator can meet all of these concerns providing 100% ventilation whilst optimizing insulation cover for energy ratings and it comes with detailed supplier instructions.
