To ensure that all electrical equipment or devices that are used to perform specific tasks, are inspected and tested and tagged
correctly, regulations require that a competent person such as a Licensed Electrician be employed to perform the required
tests.
A person competent to undertake Inspection and Testing of electrical equipment must therefore have:
 Knowledge and practical experience of electricity and its hazards.
 A clear understanding of precautions to avoid danger.
 The ability to recognise, at all times, whether it is safe for work to continue or not.
 The ability to carry out visual examinations of electrical equipment.
 The ability to distinguish between electrical equipment that is double insulated and equipment that is earthed as well as
being able to identify the appropriate test for each type.
 The competency to carry out the Earthing Continuity, Insulation Resistance or Leakage Test and RCD tests on electrical
equipment safely.
 The knowledge of how to use the relevant testing instruments, interpret and record the results for compliance with the
Standard/Workplace requirements.
 The knowledge to be able to correctly recommend the frequency of testing required.
Due to the potential hazards of electrical testing all care must be taken.
