A national recall of faulty electrical cabling has only captured 54 per cent of the total 4313 kilometres that were installed, putting thousands of homeowners at risk of house fires or electrocution.

The recall of Infinity electrical cables was launched in August 2013, after it was found the cabling could become prematurely brittle and break when placed under stress near heat sources and roof access areas.

However, four years into the Australian Competition and Consumer Commission-led recall, almost half of the dangerous cabling remains in Australian homes.

In NSW, 2384 kilometres of Infinity cabling was laid between 2010 and 2013. Since then, 433 properties have been declared safe, however 74 per cent of the dangerous cabling is yet to be remediated in homes.
