What is an RCD (safety switch)?
An RCD (Residual Current Device) is a safety switch that immediately cuts off electricity when it detects current leaking to earth or another fault path, such as through a person, stopping electrocution within milliseconds.
How many RCDs are legally required in a WA home?
Western Australian regulations require a minimum of two residual current devices (RCDs) to be installed at the time a home is sold or a new rental lease begins.
How many electrocution deaths in WA could RCDs have prevented?
Nearly 80 percent of electrocution deaths in Western Australia over the last 17 years could have been prevented if RCDs had been installed.
Are RCDs mandatory for both power and lighting circuits?
Yes. RCDs are a mandatory requirement in Western Australia for both socket outlet (power) circuits and lighting circuits.
When exactly does WA law require RCDs to be installed?
The requirement is triggered when ownership of a property is transferred or when a new rental lease is made, at which point at least two RCDs must be fitted.
Do RCDs only protect against shock, or also fire?
RCDs protect against both. By cutting power the instant a fault is detected, they prevent electric shock and reduce the risk of fires caused by faulty wiring or appliances.
