The Australian Competition and Consumer Commission (ACCC) has warned that thousands of homes remain at risk of house fires due to the installation of faulty Infinity cables.

The ACCC has warned the dangerous cables can become prematurely brittle and break when placed under stress near heat sources and roof access areas. This could lead to a fire or electric shock if the cables are disturbed by home owners or tradespeople.

A national recall of Infinity cables began in August 2013.

“Four years into the recall, only 54% of the 4,313 km of dangerous cable subject to a voluntary recall has been found and fixed. Your home might be a ticking time-bomb if you haven’t had Infinity cabling replaced,” said ACCC deputy chair Delia Rickard.

Infinity cables installed in NSW homes in 2010 have been found already starting to crack, with remaining states in territories, where they were installed from 2011, in danger from next year.
