Residual Current Devices (RCD), also known as safety switches, disconnect power when electrical leakage is detected. This helps reduce the risk of electric shock and electrical fire.
Regular RCD checks confirm the device trips within the required limits. Thermal Scanners provides compliant RCD trip time testing aligned with AS/NZS 3760:2022 and can be delivered alongside our broader thermal scanning services.
Regular testing ensures that these devices function correctly and remain effective in safeguarding lives and property. At Thermal Scanners, we specialise in providing professional and compliant RCD trip time testing services across Australia. Our services align with the latest Australian Standards (AS/NZS 3760:2022), offering comprehensive solutions for a variety of environments, including commercial and industrial properties.
Safeguard Health and Safety with RCD Trip Time Testing
An RCD protects against electrocution by monitoring electrical current imbalances. When an imbalance is detected, the device rapidly disconnects the power. These imbalances can occur for several reasons, including:
Accidents
Damage to wiring during repairs or renovations, dropping heavy objects on equipment or spilling liquid on electrical components.
Damaged Insulation
Physical wear or environmental factors, such as heat and moisture, can degrade wire insulation, increasing the risk of dangerous current leakage.
Improper Wiring
Loose connections, faulty wiring practices and incorrect installation of electrical outlets, switches or junction boxes.
Moisture Intrusion
Water or humidity entering electrical equipment or wiring. This can also include condensation on electrical components.
Faulty Appliances
Malfunctioning or damaged appliances, including worn cords and plugs, can cause electrical leaks and surges.
Schedule an inspection
If the RCD is not functioning correctly, faults could escalate, causing severe electrical shocks, damage to equipment, or fire risks. Contact us now to schedule regular testing and ensure your safety devices operate efficiently in the event of an electrical incident.
Types of RCD Trip Time Testing
There are two recognised methods used to verify that safety switches are operating correctly.
Push Button Test
A simple yet effective test that anyone who is trained and competent can perform. This quick check ensures your RCD is operational and ready to protect. Regardless of the site type, push-button testing is required every six months. We recommend clients perform this test themselves to save costs, as it is a low-risk and straightforward task.
Trip Time Test
A calibrated test that measures how quickly the RCD disconnects power under fault conditions. An RCD must trip within defined time limits to provide effective protection from electric shock. This test must be carried out by a licensed and certified electrician using calibrated and suitable equipment.
Safety switch testing is often completed alongside broader electrical risk assessments such as electrical thermal imaging, mechanical thermal scanning and cold room thermal imaging, providing a more complete view of asset condition and electrical safety.

How Often Should RCD Testing Be Conducted?
According to AS/NZS 3760, the required frequency for RCD testing varies depending on the site:
Commercial and Industrial Sites
Safety switch testing is required every 12 months to maintain electrical safety and compliance.
Residential and Hotels/Guest Accommodation
Testing must be conducted every two years.
Push-Button Tests
Across all site types, push-button testing is required every six months. This check can be completed by a suitably trained site representative but does not replace a full RCD trip time test.
Indicative testing and inspection intervals for electrical equipment should always be confirmed against current standards and site conditions.
| Type of environment and/or equipment | Equipment including | Interval between inspection and tests | ||||
|---|---|---|---|---|---|---|
| Class 1 equipment, cord sets, cord extension sets and EPODS | Residual current devices | Push-button test - by user | Operating time and push-button test | |||

| Environment where the equipment or supply flexible cord is subject to flexing in normal use OR is open to abuse OR is in a hostile environment | 12 mths | 6 mths | 6 mths | 6 mths | 12 mths | 12 mths |
| Environment where the equipment or supply flexible cord is NOT subject to flexing in normal use and is NOT open to abuse and is NOT in a hostile environment | 5 yrs | 3 mths | 6 mths | 6 mths | 2 yrs | 2 yrs |
| Residential type areas of: hotels, residential institutions, motels, boarding houses, halls, hostels accommodation houses, and the like | 2 yrs | 6 mths | 6 mths | 6 mths | 2 yrs | 2 yrs |

How RCD Testing is Conducted
RCD trip time testing involves measuring the disconnection time of the residual current device when a fault current is applied. At Thermal Scanners, our qualified technicians conduct testing directly at the electrical board, rather than at individual power points, ensuring that both power and lighting circuits are thoroughly inspected.
We test the RCD on both the positive and negative sides of the wave, identifying the worst-case trip time. This provides a more comprehensive assessment of the device’s performance, ensuring the highest level of safety and reliability and is required under AS3760.
Compliance Reporting Made Simple
After completing your RCD testing, we provide a comprehensive compliance report that details the performance of every breaker on-site. This essential document not only supports safety audits but also ensures you meet all regulatory requirements with ease.
Queensland Clients, Take Note! Depending on your property type and if it is RCD-protected and has been tested, you’re exempt from Test & Tag requirements. This means streamlined compliance, reduced maintenance costs, and one less thing to worry about.
Trust Thermal Scanners for your RCD testing needs. We’ll help you maintain safe, compliant, and up-to-date premises, aligned with the latest standards. Contact us today to schedule your safety switch testing and experience peace of mind like never before.
Frequently Asked Questions
What is the difference between a safety switch and a circuit breaker?
A circuit breaker protects wiring and electrical equipment from overloads and short circuits. A safety switch, also known as an RCD, is designed to protect people by disconnecting power when electrical leakage is detected, reducing the risk of electrocution.
Can RCD testing cause downtime for my business?
RCD trip time testing requires a brief power interruption. Thermal Scanners plans testing carefully and works with site teams to minimise disruption and maintain continuity of operations wherever possible.
Can I perform RCD testing myself using the 'Test' button?
The push-button test can be performed by a qualified specialist and confirms that the RCD can trip. A full operating time test measures how quickly the device disconnects power and must be completed by a technician using calibrated test equipment.
Do I need to test RCDs in a new commercial building or after renovations?
Yes. Under AS/NZS 3000, all new electrical installations and altered circuits must have RCDs tested before they are commissioned and placed into service.
