Calls for Electricians to Have Their Say on New National Wiring Rules

  • The National Standards Authority of Ireland is urging electricians to have their say on the draft National Wiring Rules, which are open for public consultation until February 28th 2019

  • It is the first major revision to the National Wiring Rules in over a decade

  • A number of key changes have been made in areas like electrical installation, safety and energy efficiency

The National Standards Authority of Ireland (NSAI) is urging the more than 4000 registered electrical
contractors in Ireland, and all those working in the electrotechnical sector to have their say on the
proposed National Wiring Rules.
The new rules, have been developed through the National Standards Authority of Ireland, by industry experts who sit on the NSAI’s Electro Technical Committee (ETC TC2) “Electrical Installations”
The National Wiring Rules are essential for electricians, inspectors and regulators as they specify the
electrical installation safety requirements for all premises in Ireland.


It has been over ten years since the publication of ET101 in Ireland. There has been a significant change in the regulatory and standards development landscape. Under the Electricity Regulation Act (1999), the Commission for Regulation of Utilities (CRU) now regulate the safety of electrical installations in the country and Safe Electric are the Safety Supervisory body tasked with inspection and monitoring of the certification process.


NSAI seeks input from the electrotechnical industry on I.S. 10101:20xx. Anyone who wants to view the draft I.S.10101:20xx Standard and submit comments can do so by logging onto “Your Standards, Your Say” web portal through the NSAI website at


Please click on the link below to sign in and view the standard:


For comments to be considered, they must be submitted on the Official NSAI commenting template.

The public consultation phase will last until February 28th, 2019.

Following the public enquiry, all comments received will be reviewed by TC2 (committee) experts and used to enhance the quality of the final Standard before publication in 2019.


Post publication, there will be a six-month transition period before the new requirements come into effect. However, installations may be designed in accordance with the ‘new version’ before that date.


In terms of standards development, NSAI are now responsible for providing a comprehensive set of standards for the electrical industry. In respect of the new National Rules for Electrical Installations, NSAI ETC Technical Committee (TC) 2 is specifically Ireland’s national mirror committee responsible for maintenance and development of these rules.


It is important also to highlight that the European Committee for Electrotechnical Standardisation (CENELEC) have continued to revise the 60364 series of Harmonisation Documents for which there is ongoing adoption by European member states. These documents form the basis for the development of national wiring rules, and Ireland, through the national mirror committee (i.e. ETC TC2) has had a vote and a say in developing these documents.


This article aims to highlight some of the key proposed changes in the new standard and describe how you can get involved in the public consultation phase.
