When developing a test and tag program I am often asked ” What is RCDRCD is an acronym for Residual Current Device. They are also known as safety switches. RCDs are designed to protect people from electric shock. testing? ”
Residual current devices, or RCDs as they are more commonly called, are important safety devices that can save your life.
Here is a very short, non-technical explanation of how they work and what they do.
An RCDRCD is an acronym for Residual Current Device. They are also known as safety switches. RCDs are designed to protect people from electric shock. is a device that measures how much current is flowing on the active/live conductor and the neutral conductor of a circuit or appliance. These values should be the same or very close to being the same. If there is a variation, there could be current flowing to “earth” which means there could be a defect in the circuit or an appliance connected to it. When the variation between the active and neutral readings is greater than a specific value the RCDRCD is an acronym for Residual Current Device. They are also known as safety switches. RCDs are designed to protect people from electric shock. will “trip” and shut off the power supply to that circuit. When that happens the user of the appliance is protected from a potential electric shock.
RCDs will only protect you if they are working and react (trip) fast enough. To ensure the RCDRCD is an acronym for Residual Current Device. They are also known as safety switches. RCDs are designed to protect people from electric shock. is functioning correctly it must be tested on a regular basis. This requires specialised test equipment and testing procedures. The procedure involves simulating a defect and measuring the trip timeThe trip time is the measurement of the time taken for a Residual Current Device (RCD) to trip (break the circuit). This should occur when a value greater than the rated tripping current of the RCD is detected. The measurement is recorded in milli-seconds. We provide RCD or trip time testing in Melbourne for any business or workplace. to within 1/1,000th of a second.
