G Class Licensed Electrical Inspectors (LEI) Training

The 'G Class' Electrician's Licence entitles the licence holder to carry out electrical inspection work in Victoria.

The Licensed Electrical Inspectors (LEI) assessment is a requirement for experienced electricians who are looking to become Energy Safe Victoria (ESV) G Class Electrical Inspectors.

TTA offers training for those preparing to sit their LEI assessments.

Our teaching style is 1:1, providing each student with individualised learning feedback.

Students will train in the three components assessed in the LEI assessment:

  • G Class Theory
  • G Class Practical
  • G Class Safe Approach

Rant from the Director

As an ESV Electrical Inspector, you can get off the tools and find unlimited work; it's the electrician’s ideal retirement plan.

As experienced electricians, we've encountered many unsafe electrical installations. Being an inspector, you can apply your valuable industry experience to fix these hazards before an accident occurs.

But just practical experience isn't enough. An inspector must be fully competent with the Wiring Rules, Regulations, Construction and Demolition Rules, the Electrical Safety Act and the ESV Defects List.

So what are the expectations of the LEI exam?

  • A thorough knowledge of AS/NZS 3000. ESV provides every candidate with a set of clean, unmarked, standards. This means being able find wiring rules very quickly and quote significant rules from memory.
  • A thorough understanding of an inspector's obligations, as per the Electrical Safety Installation Regulations.
  • An understanding of the responsibilities that an ESV Inspector must uphold, despite the economic pressure that may be placed on an inspector, by RECs, employers or your own financial commitments.
  • A very thorough understanding of doing the right thing by being the safeguard of the Victorian community in their personal electrical safety.
  • You must be guided by a code of ethics, for your reputation, in case unfounded allegations are made against you in your role as an ESV inspector.
  • Understanding of the penalties against you if you use your role as an ESV Inspector to take shortcuts in your endorsement of a safe electrical installation.

This course provides the knowledge required to sit the LEI Assessments.


See the ESV website for the most up-to-date list of prerequisites required to sit the LEI assessments.
