Frequent asked questions
What is testing and tagging?
Electrical testing and tagging is the visual inspection and testing of plug-in 240V or 415V electrical items. All workplaces across Australia have a duty of care and must be able to demonstrate safe operation systems, including electrical safety.
Testing and tagging is a method that reduces the risk of electrical shock to your employees, customers and visitors.
Each electrical equipment is thoroughly visual inspected, tested with a PAT-tester and has a tag put on the lead. ElectroTechnics uses digitally printed stickers with all required details. Furthermore, we use heavy duty tags, which resist dirt, oils, etc. A detailed report emailed to you as a PDF contains all test results.
Do you test and tag outside the normal trading hours?
All test and tag bookings can be arranged during office hours from 8.00 am till 5.30 pm Monday to Friday. Contact outside these trading hours by email firstname.lastname@example.org or via our contact form.
We can make arrangements to visit your business outside these hours or on the weekend to assure there is minimal disruption. Pricing for this service may differ from our standard rates.
What are the tag colours on construction and demolition sites?
The tag, which may be colour coded to identify the period in which the test was performed, shall include
- the name of the person or the company who performed the tests; and
- test or re-test date.
According to the Worksafe NSW website and AS/NZS 3012, colour coded tags for each period are optional. Some constructions companies may set this colour codes as a requirement for the labourers and subcontractors on site. Because of this and also for easy identification, ElectroTechnics Test & Tag uses this recommended colour code:
Red – December, January, February
Green – March, April, May
Blue – June, July, August
Yellow – September, October, November
What is the difference between a Class I and Class II appliance?
A Class I appliance has it chassis and/or other metal parts connected to the electrical earth with an earth conductor (green/yellow). When we perform an earth resistant test, we measure the resistance between the chassis and the earth pin of the plug.
A Class II appliance is electrical double insulated and its construction allows not having an earth conductor. All Class II appliances must have a double square (square in a square) symbol and/or the text ‘Double insulated’ on the data plate.
What is the trip time of an RCD switch?
When testing and tagging a residual current device (RCD), we check if it is a Type I or Type II classification. The RCD may be fixed or portable (PRCD), but this has no impact on the trip time.
Type I : ≤ 10mA
Type II : > 10 mA and ≤ 30 mA
RCD’s are tested according to the type of RCD and the maximum tripping time shall not exceed the following values:
RCD Type I, with a test current of 10 mA: Maximum tripping time is 40 ms,
RCD Type II, with a test current of 30 mA: Maximum tripping time is 300 ms.
Permanently wired to terminals in equipment RCD’s shall be tested using the RCD test button only.
What happens when equipment fails the tests?
When there is non-compliance with the current standard, the equipment shall be appropriately labelled. This to indicate the equipment needs further action and also as a warning against further use.
The choice of remedial procedure, disposal or other corrective action shall be determined by the owner or the person responsible for the safety of the site where the equipment is used.
