20 ELECTRIC.IE • The Magazine & Website for the Irish Electrical Industry • Industry News Update on Ireland's new National Rules for Electrical Installations IS:10101 ‒ Charles Dunn M.Sc MIET MCIBSE MIHEEM S ince the nationwide presentations by NSAI-TC2 early 2019, much has been happening in the background to get the new Rules on the road. Reaction to the Draft for Public Consultation was huge, with lots of comments received by NSAI to be addressed. Many thanks to you all for your valuable input. Some of the ideas can be implemented now, and others may have to wait until further revisions of the rules. The NSAI system assures that all of your comments have been read and considered by the technical committee TC2. ET:101 National Rules for Electrical Installations (4th edition) will be revised and released as an Irish Standard IS:10101. The National Rules for Electrical Installations in the UK has been British Standard BS:7671 for many years, so the move to NSAI and the creation of an Irish Standard for Ireland's National Rules is a natural progression. The UK revised and released their 18th edition of BS:7671 in 2018, allowing Ireland to benefit from the experience on how to revise and incorporate public comment into the launch of IS:10101. Right now, the document is having a final check over (there are over 700 pages in it) and the NSAI planned publication date is January 2020. But that’s just getting the book out. Everyone will have time to study the new rules and train up, before implementation date which is planned for around July 2020. CRU will determine the actual implementation date, under the Electricity Regulation Act 1999, so look out for news from CRU for the exact date. Publication date will be that date when the new book is available to purchase from NSAI. Implementation date will be that date from which all new electrical installations will need to be designed to the new rules IS:10101. Electrical installations which have already been designed to the old rules ET:101 can still be installed and certified to the old rules ET:101. One of the big changes will be the new cables standard, with all cables to be rated Class Dca s2,d2,a2 in accordance with EN50575. Suppliers are already working on this change to ensure that old stocks are run down in time for the new implementation. Arc Fault Detection devices AFDDs will be “recommended” for certain high risk installations. AFDDs are in use in other countries, and will eventually become mandatory. The AFDD introduction phase will be similar to that experienced with residual current devices, with ELCBs and RCDs RCBOs initially taking some time to understand and accept. Eventually AFDDs will become safety devices that are the accepted norm, and suppliers are already working to provide sample products and wiring installation instructions. The new requirement for residual current devices for domestic lighting circuits will be a little easier to implement, as RCDs and RCBOs are already widely available. As a response to the Public Consultation process, the proposed requirement for distribution boards What is new in IS:10101? •Residual Current Devices (RCDs) on lighting circuits in domestic premises. •Arc Fault Detection Devices (AFDDs) will now be recommended •Electromagnetic Compatibility (EMC) Directive •Cables to be rated Class Dca s2,d2,a2 in accordance with EN50575. •Distribution boards in domestic installations to be non combustible •Residual current devices (RCDs) Type AC are not recommended •Model certificates have now been removed. •Energy Efficiency, Appendix 8
