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. Neither is it designed for field use by electrical tradesmen and inspectors for testing compliance with national wiring standards. However, this standard is not written in such language that it can readily be adopted as a national wiring code. Hence national standards follow an identical system of sections and chapters. In European countries, an attempt has been made to harmonise national wiring standards in an IEC standard, IEC 60364 Electrical Installations for Buildings. The standard is mandatory in both New Zealand and Australia therefore, all electrical work covered by the standard must comply. 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. They are usually based on a model code (with or without local amendments) produced by a national or international standards organisation, such as the IEC. Wiring installation codes and regulations are intended to protect people and property from electrical shock and fire hazards.

Wiring codes of practice and regulations The International Electrotechnical Commission (IEC) is attempting to harmonise wiring standards among member countries, but significant variations in design and installation requirements still exist. Wiring safety codes vary by locality, country, or region. Allowable wire and cable types and sizes are specified according to the circuit operating voltage and electric current capability, with further restrictions on the environmental conditions, such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals.Īssociated circuit protection, control, and distribution devices within a building's wiring system are subject to voltage, current, and functional specifications. Wiring is subject to safety standards for design and installation. ![]() For help with product selection and use, consult your on-site safety professional, industrial hygienist, or other subject matter expert.Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets, and light fittings in a structure.
