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

As a person conducting a business or undertaking (PCBU), you have the responsibility to make sure your workplace is safe. Having your plug-in electrical appliances, tools and other equipment tested and tagged regularly is an important step.

We refer to the recommended timetable to see how often we check your workplace.

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

If you have any questions or want to have a free risk-analysis, please don’t hesitate to contact us.

Test & Tag

ElectroTechnics is a registered and fully insured Test and Tag company. We use the latest PAT-testers, this way we can offer you detailed reports at a minimum downtime.

Additionally, all our technicians have the police and working with children check 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 needs 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 (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), know 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/RCCB’s are designed to disconnect power to the circuit when a difference is detected. For example, when a person touches an appliance with a lose active wire that is touching the metal casing, a current will flow through the 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 10 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, a second time on the negative start polarity.
