Residual Current Devices (RCDs) – also known as “safety switches” – are an important safety device that are most known for protection against electric shock.
RCDs are designed to protect people from electric shock, earth leakages, faulty or mixed wiring, short circuits and potential fires whereas circuit breakers only detect overload or short circuits.
RCDs are typically found in the switch-board’s and sub boards of commercial, industrial buildings as well as homes. You may find that a lot of appliances, leads or power boards come with RCDs from the manufacturer these days.
Portable RCDs are also available that plug directly into a power outlet. Many generators have RCDs incorporated into the power outlets.
As part of your electrical safety program, ALL the RCDs used in a workplace MUST be tested regularly to ensure they are working correctly. The reason they need regular testing is dust, grit, electrical over loads, faults high voltage fluctuations, lack of use or physical damage can cause the internal components to fail or the moving parts to “stick”, slow down or prevent it from tripping at all! You don’t want that happen.
The Standard AS/NZS 3760 sets out the maximum tripping time for a Type II RCD shall not be greater than 300 milli seconds. That’s 0.300 of a second and is actually faster than you can blink!
There are two tests that need to be regularly performed;
The “push button” test is designed to provide an indication the RCD is working; you simply push the “test button” and the RCD should trip “without undue delay”. However it is not particularly accurate and should never be relied on as a reliable assessment of the RCD working correctly.
The “trip time” test using the “Milli Amp current” method is a much more accurate means of testing RCDs and is a required test under AS/NZS 3760. It measures the actual trip time and must be performed with equipment able to measure this to within +/- 8ms ( 0.008 of a second ).
The Standard also sets out the intervals to retest the RCDs under various uses and environments. For commercial cleaning use it’s every 6 months, workshops and the like every 12 months, residential facilities and low risk environments every 2 years.

A residual current device, also known as a safety switch, is a device that offers essential safety protection from any electric-related incidents, including electrical shocks and fires. Installing one for your commercial building can be the best life-saving measure since RCDs can easily detect faulty wiring, defective electrical appliances, and even water in your electrical system.
While RCDs are an excellent addition to your electrical systems, regular testing and maintenance are necessary to prevent disasters in your property – be it an industrial facility or an office building.
