To be an ESV Electrical Inspector, you must be fully competent with the Wiring Rules, Installation Regulations, Construction and Demolition Rules, the Electrical Safety Act and the ESV Defects list.

Documentation is a big part of being an ESV Electrical Inspector. So, if you don't like paperwork or computer lodgement on ESV Connect, then being an inspector is not for you.

However, as we get to be an older mature electrician, we can't fit in roof spaces any more and our physical flexibility, and strength is not what it used to be. But we do gain valuable industry experience and have seen and experienced many unsafe electrical installations. So, this is an ideal application for your mature age and experience.

At TTA we have a 3 tier program. We know you are experienced and very good at the practical application of your knowledge as an Electrican. However, you must have a thorough knowledge of AS/NZS 3000.

Why? Because every G Class assessment requires a clean set of unmarked, ESV provided AS/NZS 3000 Wiring Rules.

You must complete the AS/NZS 3000 Wiring Rules course at TTA to be successful in all 3 parts of the G Class Electrical Inspectors assessment. Why? You must be able to identify the visual defects with the associated wiring rule and the ESV defect, that you must provide on the Certificate of Electrical Safety for your REC.

This course provides the knowledge required to sit the Licensed Electrical Inspector (LEI) Assessments.

Students will learn about:

  • G Class Theory,
  • G Class Practical,
  • Safe Approach.

These are the three components assessed in the LEI exam.


See the ESV website for prerequisites (opens link in new tab).
