RCD Testing & Compliance
Northern Rivers NSW.
Regular RCD (safety switch) testing is a legal requirement for many property types in NSW, and a critical safety practice for all of them. We test, document, and certify, so you have proof your electrical protection is working.
What is RCD Testing?
An RCD (Residual Current Device), commonly called a safety switch, is the device that cuts power within milliseconds if it detects a fault, potentially saving a life. Testing confirms each RCD operates correctly and within the required trip time.
Australian Standard AS/NZS 3760 and NSW Work Health and Safety Regulations require periodic RCD testing in workplaces, rental properties, and commercial premises. Many insurance policies also require evidence of tested and compliant safety switches. Without testing, you have no way of knowing whether the switch that is supposed to protect you will actually operate when it counts.
What We Test
Push-button test
The basic functional test every occupant should perform quarterly, confirmed by our technician as a baseline check.
Trip time test
Using calibrated test equipment, we measure the RCD's actual trip time against the AS/NZS 3760 standard. A slow or non-tripping RCD fails compliance, regardless of its age.
Loop impedance check
We verify the circuit can deliver enough fault current for the RCD to operate correctly, not just the device in isolation.
Documentation and certification
Every test produces a written record: device ID, circuit, test date, result, and next due date. You receive a certificate you can give to insurers, property managers, or WHS officers.
Failed RCD replacement
If a device fails testing, we carry stock to replace it on the spot. No second visit required in most cases.
Testing Intervals by Property Type
Under AS/NZS 3760 and NSW WHS Regulations, testing frequency depends on how the property is used:
Workplaces (hostile environments)
Every 3 months (push-button test) and every 12 months (full test). Construction sites, workshops, and outdoor commercial settings.
Workplaces (normal environments)
Every 6 months (push-button) and every 5 years (full test). Offices, retail, hospitality, and similar settings.
Rental properties (NSW)
NSW regulations require that all RCDs and smoke alarms in rental properties be tested and maintained. We provide landlord compliance reports suitable for property managers.
Residential (owner-occupied)
No statutory interval, but we recommend full testing every 3 years, or when purchasing a property or completing renovations.
When to book testing
- →You manage a rental property in NSW
- →Your WHS compliance is due for renewal
- →You have never had your safety switches tested
- →Your insurer or property manager has requested certification

- →You are buying or settling a property
Bundled with Test & Tag?
If your workplace also needs portable appliance testing (Test & Tag under AS/NZS 3760), we run both on the same visit. One report, one certificate, one invoice.
