Thousands of NSW families will become vulnerable to fires and electrocutions from early next year unless they rid their homes of recalled, faulty cabling, authorities warn.

Those who have had electrical work carried out in their home between 2010 and 2013 are being urged to contact their electrician to determine whether Infinity cabling was used.

Homeowners who had electrical cables installed between 2010 and 2013 are being urged to call on a licensed electrician to inspect their home, if they have not already done so.

About one year into the national mandatory recall of Infinity electrical cabling, only 2 per cent of the 1850 kilometres laced through NSW homes and businesses has been replaced.

That is, only 92 NSW properties have been rendered "safe", according to new data from the Australian Competition and Consumer Commission.
