Ireland's NEW WIRING REGULATIONS – Everything you need to know about the IS10101 transition period.
Monday 30th November -0001
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 transition period began from 1 April 2020. Electrical installations may be designed to the new standard from this date.
After ten months (from 1 February 2021), all new electrical installations must be designed and certified to the new standard.
After 28 months (from 1 August 2022), all electrical installations must be certified to the new standard.
Installations may be designed to the old standard until 31 January 2021, provided they are certified to at least a pre-connection stage by 31 July 2022.
