Commercial RCD Testing

South-West Victoria (Warrnambool, Port Fairy, Hamilton & Surrounds)

Every workplace relies on electricity — but one faulty circuit can seriously injure a worker in milliseconds.

Residual Current Devices (RCDs), often called safety switches, are the primary protection against electric shock.
However, simply installing them isn’t enough. Under Australian Standards, they must be regularly tested and documented to remain compliant.

TEIGE Electrical Services provides professional commercial RCD testing and certification across South-West Victoria for:

• Workshops & factories
• Farms & dairies
• Offices & retail shops
• Schools & community buildings
• Construction sites
• Rental & managed properties

What Is an RCD — And Why Testing Matters

An RCD monitors the flow of electricity and instantly shuts off power if it detects leakage — typically when current flows through a person to earth.

It operates in about 30 milliseconds — faster than the human heart can go into fibrillation.

But here’s the critical point:

An RCD can fail mechanically or electrically — and you won’t know until someone gets hurt.

Many RCDs fail due to:

  • Dust and insects inside switchboards
  • Moisture ingress
  • Loose neutrals
  • Age and worn contacts
  • Incorrect wiring
  • No trip sensitivity

That’s why legislation requires push-button testing AND instrument testing at scheduled intervals.

Legal Requirements (Australia)

Commercial RCD testing is not optional.
Workplaces must comply with:

  • AS/NZS 3760:2022 – In-service inspection & testing of electrical equipment
  • AS/NZS 3012 – Construction & demolition sites
  • AS/NZS 3000 – Wiring Rules
  • OHS Regulations / WorkSafe Duty of Care

Failure to test can result in:

  • WorkSafe fines
  • Insurance refusal after incidents
  • Personal liability for business owners or property managers

What TEIGE Tests (Not Just the Button)

Many companies only press the test button.
That is NOT compliant testing.

We perform calibrated instrument verification:

✔ Trip time testing
✔ Trip current testing
✔ Ramp testing (sensitivity)
✔ Polarity & earth verification
✔ Visual inspection of switchboard
✔ Mechanical operation check
✔ Load fault simulation

Documentation You Receive

After testing you get a professional compliance record suitable for auditors, insurers and WorkSafe:

  • RCD Test Report (pass/fail per device)
  • Asset identification labelling
  • Photo evidence
  • Non-compliance notices (if required)
  • Repair recommendations
  • Service reminder scheduling

Unlike general test-and-tag companies, we are licensed electricians — meaning we can repair faults immediatelyinstead of just failing your site.

This avoids shutdowns and repeat callouts.

You’re not just getting a checklist — you’re getting a qualified electrical safety inspection.
