This course covers the requirements laid down in the standard AS/NZS 3000, commonly known as the Australia – New Zealand Wiring Rules. For those installations covered in the scope of this standard, its provisions are mandatory and must be followed. Any engineer involved in the planning and design of electrical systems, their installation, or maintenance, must have a clear idea about the various requirements contained in the standard.
The primary purpose of this standard, like many of its various other equivalent national standards, is to ensure the safety of personnel against the dangers arising from the use and handling of electrical equipment and appliances. The introductory modules of this course outline the basic principles that should be understood for a better appreciation of the standard. These include modules that illustrate the calculation for the power demand of a system and the computation of earth fault currents, as discussed in the appendices of the standard. These are informative and are very important in making an electrical system safe for operation. The actual provisions of the standard are then discussed in detail in the subsequent modules.
Please Note: Students will need to provide their own copy of the AS/NZS 3000:2018 Standards
The course is composed of 12 modules, covering the requirements of the AS/NZS 3000 Wiring Rules and how to apply them, the importance of fulfilling the requirements for safe use of electrical equipment and systems, and simple methods of calculating to check the adequacy of conductors and protective earthing components to ensure safe operation.
