Find out where you can go for trusted answers to technical and regulatory questions.

  • Safe Work


There’s no single place to find correct, authoritative answers to the many questions you and your fellow licensed electrical workers will have in the course of your work.

Before you do seek the advice from third parties, it’s important to ensure you’ve had a look through the information available to you in regulations, standards and similar guidance documents.

Questions typically are likely to fall into 2 categories:

  • technical/engineering questions relating to design of electrical systems, or installation of equipment and interpretation of standards
  • regulatory questions on the Electricity Act, interpretation of the Electricity Safety Regulations, testing, certification, registration, licensing and limits of work.

Technical questions

While it is often helpful to seek advice, it is extremely important to understand that as a licensed electrical worker you remain fully responsible for the work you do even with or on the advice of a third party.

Irrespective of what prescribed electrical work your licence allows you to do, you are only allowed to work within your current understanding, knowledge and skills.

If you don’t know, or have doubts about the work you are doing then you need to stop. Do not carry on with the work until you are confident you can so competently. Better still, don’t attempt the work until you have the knowledge, skill and experience to complete it competently.

Undertaking work outside areas of your current competency is risky, it can to lead to unsafe situations and problems which can be difficult and costly to resolve.
