Why RCDs (Safety Switches) Are Essential for Every WA Household

Life-Saving in a Split Second

In Western Australia, at least two RCDs must be fitted to homes built since 2000 and to any home that is sold or leased. But beyond compliance, RCDs are an essential life-saving device that every homeowner should fully understand. Whether you’re renovating, building, or living in an older home, knowing the state of your RCDs can be the difference between peace of mind and a potential hazard.

What is an RCD?

A Residual Current Device (RCD) is a safety switch that shuts off power in a split second if it detects a fault, like someone receiving an electric shock or a live wire contacting water.

  • Installed on power and lighting circuits

  • Required in WA on homes built since 2000, and on homes that are sold or rented

  • Saves lives by preventing electrocution

What the Law Says in WA

Under WA’s electrical safety regulations, homes that are sold or rented must have at least two RCDs installed, protecting all power point and lighting circuits (Building and Energy, WA Government).

  • Rental properties must have the RCDs fitted before a new tenancy begins

  • Sellers must have the RCDs fitted before the land title is transferred

  • Non-compliance can result in legal penalties

How to Know If Your Home Is Protected

Many WA homes, especially older builds, may only have partial protection.

  • Look at your switchboard: Are there labelled RCDs?

  • Check regularly: Each RCD should have a ‘test’ button

  • Book a safety inspection: Handcock Electrical can assess and upgrade if needed

What Can Go Wrong Without an RCD?

  • Shocks and burns: Especially for young kids or pets

  • Fire risks: Faulty appliances can spark

  • Legal exposure: selling or renting a home without the required RCDs breaches WA’s electrical safety regulations
