Test and Tag Fremantle – Electrical Appliance Classification

Electrical appliances are crucial part of the modern world. From electric kettles to coffee machines, we are either exposed to or using one every moment of our lives. While electricity is a crucial component of daily living and for businesses, it is also a potential hazard which is why it needs to be tested and tagged.

Test and tag is a safety procedure that involves inspecting, testing, and tagging electrical appliances and equipment to ensure their safe operation. It is commonly carried out in workplaces, schools, hospitals, and other public or commercial settings where electrical appliances are used.

The purpose of test and tag is to identify any potential electrical hazards or faults in appliances that could pose a risk to the safety of users or the surrounding environment. It involves conducting a visual inspection and a series of electrical tests to assess the integrity and functionality of the appliance.

During the test and tag process, a qualified technician or an electrician will inspect the appliance for any visible signs of damage, wear, or loose connections. They will also perform a range of tests, including insulation resistance, earth continuity, and polarity testing, to ensure the appliance complies with relevant electrical safety standards and regulations. The Local Guys service all Perth Suburbs for their Test and Tag needs.

Class l vs. Class II Appliances

Both Class I and Class II appliances are electrically powered, which calls for test and tag for both classes. The AS/NZS 3760:2022 requires electrical appliances under this classification to undergo a test with a PAT tester. A PAT tester is a portable testing device designed to perform a range of electrical tests on appliances to assess their safety and compliance with electrical safety standards.

The slight differences between these two classifications of appliances is the testing method used for each.

Class I Appliances – Test and Tag Fremantle

Class I appliances are electrical appliances that rely on a combination of basic insulation and an earth connection to provide protection against electric shock. These appliances typically have a three-wire power cord with live, neutral, and earth wires.

The main characteristic of Class I appliances is their reliance on an earth connection. The earth wire is connected to the metal casing or exposed conductive parts of the appliance, providing a path for any fault current to safely flow into the ground. This helps to protect the user from electric shock in the event of a fault or insulation breakdown. Class I appliances include household appliances such as the following:

  • Washing machines
  • Refrigerators
  • Electric Heaters
  • Power tools
  • Microwaves
  • Kettles
  • Irons
  • Toasters

Class I appliances must undergo regular testing and inspection to ensure their electrical safety, including checks on the integrity of the earth connection, insulation resistance, and other relevant tests. This is where the test and tag process, including the use of PAT testers, comes into play to ensure compliance with electrical safety standards and regulations.

Class II Appliances – Test and Tag Fremantle

Class II appliances are appliances that have double insulation. They are distinguished by their double-square symbol or a square-within-a-square symbol. The double insulation serves as an additional layer of protection against electrical hazard or electrocution.

Class II appliances are electrical appliances that provide protection against electric shock without relying on an earth connection. These appliances have double insulation or reinforced insulation to provide an additional layer of protection.

Examples of Class II appliances include certain types of power tools, audio equipment, small kitchen appliances, lamps, and some medical devices. The following may be also classified as class II appliances as long as they have double insulation.

  • Hair dryers
  • Televisions
  • Computers
  • Plastic power tools
  • Photocopiers

How to Carry Out The Test?

Test and tag start with visual inspection. The technician will check the appliances for burns, and will also pull-on leads. He may also tap the appliance to check if there’s more damage, shake them, or turn some parts as part of the preliminary inspection. Then the following test may be performed:

Earth Continuity Test – It involves checking the integrity of the earth connection in an electrical appliance. A low-resistance current is passed through the earth wire, and the tester measures the resistance between the earth pin and accessible metal parts of the appliance. It ensures that in the event of a fault, the earth wire can effectively conduct any fault current to the ground, protecting the user from electric shock.

Insulation Resistance Test – This test assesses the insulation integrity of an electrical appliance. A high voltage is applied between the live parts of the appliance and its earthed parts, and the tester measures the resistance. It checks for any leakage or breakdown of insulation, which could lead to a risk of electric shock. A high insulation resistance indicates that the appliance is adequately insulated.

Further Tests on Leads, RCDs, etc. – In addition to the tests conducted directly on the appliance, further tests may need to be performed on the appliance’s leads, power cords, residual current devices (RCDs), or other components. These tests could include checks for correct wiring polarity, continuity, insulation resistance, and functionality of RCDs or other protective devices. These additional tests ensure the safety and compliance of the entire electrical system, including the various components connected to the appliances.
