Alterations: Alterations to electrical installations shall not cause any portion of the original electrical installation, or connected electrical equipment, to: (a) carry excessive currents or sustain excessive voltages; or (b) be used in any manner that is not in accordance with AS/NZS 3000:2018.
Clause 2.9 describes the requirements for protective equipment such as arc fault detection devices (AFDDs), which may be used to protect against the effects of arc faults in final subcircuits. AFDDs are required to comply with IEC 62606, and have a load current rating no less than that of the associated protective device. AFDDs are required to be located at the switchboard supplying the final subcircuit. The installation of AFDDs should be considered when carrying out alterations to final subcircuits in situations where existing wiring systems may significantly deteriorate.

Clause 3.3.2 now describes an additional external influence on wiring systems: thermal insulation. Clause 3.3.2.13 states that the rated current-carrying capacities of cables passing through bulk thermal insulation is to be calculated according to the length of cable passing through the insulation (in accordance with AS/NZS 3008.1).
A number of informative appendices have been included in the 2018 version of AS/NZS 3000, which provide useful information contained within other Australian Standards. As they are not classified as normative appendices, the information is provided to help the reader understand the intent of the standard. These are as follows:
This Appendix describes the selection of circuit protection and switching devices operated on a d.c. supply that would be deemed to meet the requirements of this Standard. Among other topics, it describes requirements for arc suppression, switchgear typing, d.c. ratings, subcircuit wiring/fittings, switchboard locations, and inverters.
Effective January 1st, 2019 was the new edition of the AS/NZS 3000 Wiring Rules Standard (Electrical Installations), which outlined over 200 changes and expanded upon the coverage of electrical installations. The changes have taken into account new technologies, new products and improvements in safety, whist clarifying on the previous versions ambiguous requirements.
One of the major changes to the AS/NZS 3000: 2018 is the mandatory Residual Current Devices (RCD) requirements for the protection of sub-circuits and relating alterations and repairs (clause 2.6.3.2.3).
Where power-outlets are being added to an existing circuit and RCD protection is required, the RCD protection is only required to be fitted at the origin of the additional wiring. Where all circuit protection on a switchboard is replaced, additional protection by RCDs are required for the final sub-circuits supplied by that board.
It's been a lengthy, expensive and (at times) annoying process, but it's definitely been worth it! All 24 templates impacted by the AS/NZS 3000:2018 Electrical Installations (Wiring Rules) changes have now been overhauled - and while we were there, we improved them too. When the changes were announced we adjusted some things immediately, but what we recently published is a far more comprehensive overhaul.
All new circuits are now protected by a Residual Current Device (RCD). In other words, wherever and whenever the load is going to be increased on the switchboard or meter, protection by RCD is required. Examples would include light circuits and power points. This brings the installation in accordance with AS/NZS 3000:2018. Of course all electrical installations need to be carried out in accordance with the new Australian Standard. Our templates deal with the safety issues, however the changes to the Australian Standards affecting general electrical installation work should be known by licensed electricians.
Just like electricians, engineers and architects must comply with electrical safety standards. Enforceable AS/NZS 3000 wiring rules apply to all premises and land. Your compliance keeps everyone safe.
You'll also look at the enhancements added to AS/NZS 3000 in 2018. You'll see how these extras aim to protect the general population and animals, and ensure infrastructure is not destroyed during an emergency.
After completing the course, you'll understand the core electrical safety concepts in the wiring rules and related standards. You'll also be able to use several methods to ensure safety when designing electrical solutions.
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.
Consider excluding the switch from the Zone 2 area by having a clearance of 0.6m from the bath (see Figure 6.1 AS/NZS 3000:2018) or the switch to be installed with a minimum degree of protection of IPX4.
Consider excluding the switch from the Zone 2 area by having a clearance of 0.15m from the side of the basin and a clearance 0.4m from above the basin (see Figure 6.13 AS/NZS 3000:2018) or the switch to be installed with a minimum degree of protection of IPX4.
Consider excluding the switch from the Zone 2 area by having a clearance of 0.6m from the shower screen entry (see Figure 6.8 AS/NZS 3000:2018) or the switch to be installed with a minimum degree of protection of IPX4.
Consider excluding the socket-outlet from the Zone 2 area by having a clearance of 0.15m from the side of the basin and a clearance 0.4m from above the basin (see Figure 6.13 AS/NZS 3000:2018).
Construction wiring (Construction and demolition wiring) means wiring systems installed to provide electrical supply for construction and demolition work, and is not intended to form part of the permanent electrical installation. The term includes:

Associated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring safety codes vary by locality, country, or region. The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist.
In Australia and New Zealand, the AS/NZS 3000 standard, commonly known as the "wiring rules", specifies requirements for the selection and installation of electrical equipment, and the design and testing of such installations. The standard is mandatory in both New Zealand and Australia; therefore, all electrical work covered by the standard must comply.
In European countries, an attempt has been made to harmonise national wiring standards in an IEC standard, IEC 60364 Electrical Installations for Buildings. Hence national standards follow an identical system of sections and chapters. However, this standard is not written in such language that it can readily be adopted as a national wiring code. Neither is it designed for field use by electrical tradesmen and inspectors for testing compliance with national wiring standards. By contrast, national codes, such as the NEC or CSA C22.1, generally exemplify the common objectives of IEC 60364, but provide specific rules in a form that allows for guidance of those installing and inspecting electrical systems. 2ff7e9595c
