If an accident happens at your workplace, can you show Worksafe NSW that you did everything in your power to prevent it from happening? If not, you could be in serious trouble!

As a person conducting a business or undertaking (PCBU), you are responsible for making sure that your workplace is safe. Having your plug-in electrical appliances, tools and other equipment tested and tagged regularly is an important workplace safety measure.

We refer to the AS/NZS 3760 recommended testing timetable to see how often we should check your workplace.

We have customers relying on us in all sorts of industries, from Kindergartens to High School, from small businesses (shops, mechanics, offices) to multinationals. We also offer 3-monthly onsite testing and tagging for contractors and tradies on construction sites.

If you have any questions about testing and tagging for workplace safety or want a free risk-analysis, please don’t hesitate to contact us.

Test & Tag

ElectroTechnics is a registered, fully insured Test and Tag company. We use the latest PAT-testers to offer you detailed reports with minimum device downtime.

Additionally, all our technicians have Police and Working With Children checks and receive regular updates on standards and regulations.

To find out more about our testing and tagging procedure, please click here.

Our test and tag service includes, but is not limited to:

  • all kind of handheld tools
  • extension leads
  • power boards
  • RCD and PRCD’s
  • grinders, lathes, sanders, …
  • kitchen equipment (toasters, microwaves, dishwashers, fridges, …)
  • battery chargers
  • office equipment (computers, printers, …)

3-Phase Testing and Tagging

Some companies have 3-phase machinery, extension leads, battery chargers etc. that need to be tested and tagged. To successfully test this 3Phase equipment, we perform the following tests:

  • Thorough visual inspection
  • Earthbound test (measuring the resistance between the metal frame and the Earth pin or, in case of an extension lead, between plug and socket)
  • Insulation resistance test
  • Earth leakage test (This is mandatory if the appliance has electronic and/or electromagnetic switching)

We have most common 3Phase adapters (different currents and pins) to check your machinery.

(P)RCD Trip Time Measurement

A residual current device (RCD) or a residual current circuit breaker (RCCB), known as a safety switch, is designed to isolate power when it detects an imbalance between the active and neutral conductor.

These imbalances are usually caused by a current leakage into the earth. This leakage can be caused by a faulty appliance, wet conditions, insects, etc.

RCD/RCCBs are designed to disconnect power to the circuit when a difference is detected. For example, when a person touches an appliance with a loose active wire that is touching the metal casing, a current will flow through their body to the earth. This disconnection, or tripping, of these 30mA circuit breakers, should happen within a legal time of 300ms, but less is better! New circuit breakers trip between approximately 10ms and 30ms.

10mA RCDs may be used in areas of increased risk. For instance, circuits supplying outdoor equipment, bathrooms, kindergartens and hospitals.

30mA trip sensitivity is the minimum requirement for providing personal protection. RCDs with lower trip sensitivity (i.e. 100mA or above), may be selected to avoid unwanted nuisance tripping when installing the RCD for equipment protection.

Testing (P)RCD’s

The purpose of this test is to ensure the proper operation of residual current devices (RCD) built into appliances/installations and portable residual current devices (PRCD). Trip-out time measurement verifies the sensitivity of a (P)RCD at selected residual currents.

We test the (P)RCD two times, first time on the positive start polarity, then a second time on the negative start polarity.
