What is RCD Testing?
RCDs (Residual Current Devices), also known as safety switches, are critical life-saving devices that automatically shut off power when they detect a fault, helping prevent electric shock and electrical fires.
RCD testing involves simulating a fault and measuring the device’s response time to ensure it trips fast enough to meet safety standards and legislation.
- RCDs cut power instantly on fault detection to prevent electric shock and fires
- Testing simulates a fault and measures trip response to ensure compliance with safety standards
- It's mandatory under WHS legislation and AS/NZS 3760:2022 for legal compliance
- Required for commercial and industrial sites, often triggered by insurer or council audits
- Routine testing avoids fines, voided claims, and reduces the risk of downtime and equipment damage
Why RCD testing matters
Ensures Compliance
Meets WHS and AS/NZS 3760:2022 requirements to satisfy regulators and insurers.
Protects Lives
Confirms safety switches work reliably to prevent electric shocks.
Reduces Downtime
Identifies faults early, avoiding unexpected outages and costly repairs.
How Often Should RCD Testing Be Done?
To meet compliance requirements under AS/NZS 3760:2022, RCD testing must be performed at regular intervals, with both professional and in-house checks recommended.
Accurate record-keeping is essential. All test results, retest dates, and device status must be documented and made available during WHS or insurance audits.
Staying on top of these intervals helps protect your team and ensures your business remains fully compliant.

Frequently asked rcd testing questions
What is the difference between an RCD and a circuit breaker?
An RCD (Residual Current Device) protects people from electric shock by detecting current leakage, while a circuit breaker protects equipment and wiring from overloads or short circuits. Both are important but serve different purposes.
Is RCD testing mandatory in NSW for businesses?
Yes. In NSW, RCD testing is required under WHS regulations for most commercial and industrial workplaces. It’s also often mandated by insurers and local councils.
How do I know how many RCDs my site has?
We can perform an on-site inspection to identify and test all RCDs on your switchboards, circuits, and power points, even if you’re unsure where they’re located.
Will RCD testing interrupt my power supply?
Yes, briefly. Each test simulates a fault and causes the circuit to trip. However, we work quickly and offer after-hours or weekend testing to minimise disruption to your operations.
What happens if an RCD fails the test?
If an RCD fails, it must be either repaired or replaced immediately. TG Testing can often perform on-the-spot repairs and retest to ensure compliance before we leave the site.
