A residual current device (RCD) is an electrical safety device that helps to prevent electrical injuries and fatalities. When using electrical equipment or power tools, hazards such as damaged leads and cords, faulty wiring and dampness can lead to serious electric shocks or electrocution.
An RCD monitors the flow of electricity and is designed to immediately within milliseconds to switch the electricity off to a circuit when electricity "leaking" to earth is detected at a level that would be harmful to a person using any electrical equipment. An RCD offers a high level of personal protection from electric shock, and also reduces the risk of fire in your workplace.
Why is Testing Required?
To ensure the correct operation of the safety device, AS/NZS 3760:2010 outlines the testing procedure and frequency required for RCDs. These tests involve;
• a simple push button test required to be performed bi-annually (every six months)
• an operational performance test of the RCD tripping time and tripping current which is required annually.
Our Electrical team can perform an audit of all switchboards utilising the latest in testing equipment to identify both the quantity and condition of the RCDs on site ensuring your compliance with the Australian Standard.
