Residual Current Devices (RCDs), also known as safety switches, are critical for protecting people and property from electric shock, electrical faults and fire.
At Atomic Electrical Group, we provide professional RCD testing in Sydney for residential, commercial and strata properties — ensuring your electrical systems are safe, compliant and operating correctly.
An RCD is designed to instantly disconnect power when it detects an electrical fault or current leakage.
Unlike circuit breakers, which protect wiring from overload, RCDs protect people from electric shock.
They are commonly installed in:
RCDs can fail over time due to:
If an RCD fails, it may not trip fast enough — putting lives and property at risk.
👉 That’s why regular RCD testing is mandatory in workplaces and strongly recommended for all properties.
Under Australian Standards, RCDs must be tested at regular intervals depending on the environment.
Typical testing intervals include:
• Construction & workshops – every 6–12 months
• Commercial environments – every 12 months
• Residential & low-risk areas – every 2 years
• High-risk or flexible equipment – more frequent testing
Testing ensures RCDs trip within the required time (typically ≤300 milliseconds) to provide effective protection.
There are two main types of testing:
✔ Push Button Test
A basic check to confirm the RCD trips — not fully reliable on its own.
✔ Trip Time Testing (Professional Test)
Performed using specialised equipment to measure the exact trip time in milliseconds.
👉 This is the required method under AS/NZS 3760.
