Residual Current Devices (RCDs) play a crucial role in protecting individuals from electric shock by detecting and quickly cutting off the power in case of electrical faults. Regular testing of these devices ensures they operate effectively when needed. In Australia and New Zealand, RCD testing is governed by AS/NZS 3760—the standard for electrical safety testing and inspection of electrical equipment in workplaces.

 

At MegaTest, we specialize in providing reliable RCD testing services to ensure your premises comply with the highest safety standards. Our services cover both general buildings and construction sites, ensuring peace of mind through rigorous testing.

 

What is AS/NZS 3760?

AS/NZS 3760 outlines the procedures and requirements for the in-service safety inspection and testing of electrical equipment, including RCDs, in various environments. It specifies testing intervals, methods, and safety standards to ensure that electrical installations are functioning safely and in line with legal requirements.

​

What is an RCD?

An RCD is a life-saving device designed to prevent electric shock by cutting off the electrical supply when it detects a fault in the circuit. RCDs protect against direct and indirect contact with live components and can detect leakage currents that could result in electrocution or fire.

 

RCD Testing Intervals Under AS/NZS 3760

The frequency of RCD testing depends on the environment in which the devices are installed. The testing intervals ensure that devices are regularly inspected to maintain optimum performance. MegaTest offers testing services tailored to these intervals:

​

For Buildings (Commercial and Residential):

 

• Six months: Portable RCDs that are moved or handled frequently, or exposed to rough conditions.

• 12 months: RCDs in a fixed installation or on equipment used in less demanding environments.
   

For Construction Sites:
 

• Daily, before use: Portable RCDs used on construction sites must be visually inspected for damage or wear.

 

• Three months: Testing for construction and demolition sites is more frequent, reflecting the higher risk environment. All RCDs used on such sites must be tested every three months to ensure reliability.

RCD Testing in Medical Environments – AS/NZS 3003

While AS/NZS 3760 covers general environments, medical areas, such as hospitals and clinics, require a higher level of electrical safety. In body-protected areas, where patient contact with electrical equipment is more direct and riskier, special testing requirements apply. These areas must comply with AS/NZS 3003, which addresses electrical installations in healthcare settings.

​

RCD testing in body-protected medical areas can only be conducted by qualified persons who are certified to the AS/NZS 3003 standard. The specific requirements of AS/NZS 3003 ensure that electrical systems in medical facilities are not only safe but also suitable for the critical environments they serve. At MegaTest, we ensure that RCD testing in medical areas is performed by specialists who understand and comply with the stringent requirements of AS/NZS 3003, not AS/NZS 3760.
