Ireland’s new National Rules for Electrical Installations (previously referred to as the National Wiring Rules) have been published by the NSAI. The document is the first major revision to the standard in over 10 years and is based on internationally agreed standards for safety of electrical installations.
The new standard, also known as I.S. 10101:2020, will replace ET 101:2008, and has been produced by industry experts who sit on the NSAI’s Electro Technical Committee (ETC/TC 2) “Electrical Installations”. The standard includes requirements for design and installation of all types of installations including housing, hospitals, agricultural buildings, caravans, construction sites, industrial premises and swimming pools.
The National Rules for Electrical Installations are essential for electricians, inspectors and regulators as they specify the safety requirements for electrical installations in all types of premises in Ireland. The revisions bring requirements in line with recent technical developments and best practice in Europe, including new technologies such as electric cars, adaptation for IT connections , and guidance on energy efficiencies.
For details about transition arrangements from ET 101:2008 to I.S. 10101:2020 please refer to the Safe Electric website www.safeelectric.ie
