Life-Saving in a Split Second
WA regulations require safety switches (or RCDs) in all residential properties. 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.
