Electrical Testing

Last Updated on March 16, 2024 by Nasir Hanif

Before you buy electrical equipment or hire a professional to do a test, you should know all the basic information about electrical testing and tagging. The Occupational Safety and Health Act 1984 requires workplaces to ensure that their electrical equipment is safe. The Occupational Safety and Health Regulations 1996 stipulate that a competent person must conduct the test. The frequency of testing and tagging also needs to be considered.

Test connections

If you are in the market for portable electronic devices that use electricity, it is important to test your equipment and ensure proper connections before you use it. In general, you should test your appliances that connect to 240V or 415V power. The testing and tagging process should also be performed on appliances that are located in commercial environments. Testing and tagging intervals vary depending on your business, type of equipment, environment, and risk level.

Winding resistance measurements

To determine winding resistance, a transformer is tested by applying a constant dc test current and observing the time needed to disconnect the leads from the test source. The test voltage can be 25,000 volts, so the time needed to disconnect the leads must be sufficient to allow the transformer’s magnetic field to dissipate this energy. In large transformers, this process may take several minutes.


When installing new electrical equipment in your workplace, make sure that all of your switches and outlet sockets have an RCD. RCD Testing are important devices that protect workers and other people from the dangers of electricity. They can protect people from electric shock or even fire. But even if your RCDs are in perfect working order, they can still fail. To avoid serious consequences, make sure that you test and tag your RCDs regularly.

Frequency of testing and tagging

When is the right time to test electrical equipment? You might be surprised to learn that workplaces have different requirements for electrical testing and tagging. This is because of the different environments electrical equipment may be used in. In these environments, electrical equipment should be tested more frequently to ensure safety. Without regular testing and tagging, you could be leaving yourself or others vulnerable to electrical hazards. Luckily, Australian law makes it mandatory for workplaces to regularly test and tag electrical equipment.

Occupational health and safety implications of testing and tagging

The Health and Safety Regulation 2001 does not specifically state the regulations for testing and tagging. However, the regulations do require that workplaces test and tag electrical equipment. Occupational health and safety regulations for tagging electrical equipment in construction work include identifying hazardous environments, as well as ensuring compliance with current standards. A workplace that uses electrical equipment should be tagged on a regular basis to ensure compliance and protect the health of workers.
