RCD’S (Residual Current Devices)

Laws introduced in 2009 require all home sellers (before sale) and landlords to install RCD’s, protecting all power and lighting circuits.

In Western Australia, the law requires RCD’s to be installed on power and lighting circuits in all rental and sale properties.

What is an RCD?

An RCD is a device installed in your switchboard that monitors the flow of electricity from the main switchboard. RCD’s prevent electrocution by cutting the electricity supply if an imbalance in the current is detected. For example, if you are cutting a hole in your wall and cut a cable.

Australian Standards require RCD’s to operate within 300ms in domestic installations. This is to prevent the heart from going into ventricular fibrillation.

Who should have RCD’s installed?

In Western Australia, the law requires RCD’s to be installed on power and lighting circuits in all rental and sale properties. However, even if you are not selling or renting your property, you and your family are at risk of serious injury or death if you do not have them installed on your switchboard.

All properties constructed from the year 2000 should already have RCD’s fitted. However, many older properties still do not have them installed. Sometimes they may only have one unit installed.

By installing two units on your switchboard, the property’s circuits can be divided evenly. This ensures some light and power remain if one unit fails. This also minimises faulty operation from appliances which have low-level leakage current.
