Assessment and Planning:

Visual Inspection: A technician will thoroughly examine the appliance for any physical damage like frayed cords, cracked casings, or loose plugs.

Earthing Checks: This verifies that the appliance's earthing system functions correctly, providing a path for any stray current to flow safely away from the user.

Leakage Current Testing: This test measures the amount of electrical current leaking from the appliance. Excessive leakage can indicate potential faults and fire hazards.

Insulation Testing: This test checks the integrity of the electrical insulation within the appliance to ensure it can withstand expected voltage levels.

Polarity Testing: This applies to appliances with polarized plugs (one prong wider than the other), ensuring proper connection and preventing potential shock hazards.

Tagging:

If an appliance passes all the tests, it receives a tag. This tag typically includes the following information:

Date of Test

Name of the Tester/Company

Next Test Due Date

Unique Identification Number

Pass/Fail Status (may not be displayed publicly)

Additional Services (may vary by company):

Exit Light Maintenance: Testing and ensuring the proper functioning of emergency exit lights.

Basic Repairs: Some companies might offer minor repairs on appliances identified with electrical issues during testing.

3 Phase Testing: This specialized testing is required for appliances that use three-phase power supply, commonly found in industrial settings.

RCD/Safety Switch Testing: Residual Current Devices (RCDs) are safety switches that cut off power in case of a current leak. Test and Tag services can verify their functionality.
