What is an RCD?

An RCD is commonly referred to as a safety switch. RCD testing is the compliance testing of a Residual Current Device that is a sensitive life-saving component of your electrical board, which is designed to prevent you from getting a fatal electric shock if you touch something live, such as a bare wire or from a faulty electrical appliance. It also provides protection from electrical fires. RCD’s offer a level of protection and reassurance that ordinary fuses and circuit breakers cannot.

How It Works.

To test these in your home or office, our electrician will use an RCD testing device to measure the exact time and amperage your RCD takes to trip. This testing device is a precision instrument and will record the reading in milliseconds and milliamps. If your device does not meet the maximum trip time it fails the test and we can perform any rectification or works required to comply.

What you need to know about RCD Testing

RCD tripping will occur when a neutral or earth fault is identified by the switch when the circuit output current is different to the return current.
If the RCD continually trips (or intermittently trips) this indicates a fault somewhere in the circuit which must be located and rectified for safety reasons.
Faulty electronics, equipment, and wiring can put people at risk of electrocution, electrical burns, and injuries or property damage due to fire.
An RCD could save your life in the event of an earth fault. It acts by ensuring the electrical current is cut off if there's any current leaking through a faulty appliance.
If your RCD trips and you cannot reset it, or after resetting it trips again, you may have a faulty device and it will need to be checked by a licensed electrician.
Your RCD should be tested regularly and according to the Australian & New Zealand standards.
