The installation rule named here is the NSAI standard for how a low-voltage electrical installation is designed, erected and verified. It is not S.I. No. 264/2013. NSAI says: “I.S. 10101 specifies the requirements for the design, erection, and verification of low-voltage electrical installations.” NSAI says: “I.S. 10101 was published by NSAI on Friday 6th March 2020.” The same NSAI page says: “An amendment to the standard I.S. 10101:2020+AC1:2020 was published, as a consolidated standard, the week of 23rd September 2024.” The current sales version written on that page is I.S. 10101:2020+A1:2024/AC2:2025. I.S. 10101 is not this statutory instrument.
S.I. No. 264/2013 is the Electricity Regulation Act 1999 (Restricted Electrical Works) Regulations 2013. It is only the rule about who may do designated domestic works, not how the wiring is made. Section 9E(3) of the Electricity Regulation Act 1999, inserted by section 4 of the Energy (Miscellaneous Provisions) Act 2006, says: “A person shall not carry out electrical works which are designated electrical works unless that person is a registered electrical contractor.” That is who may do the work. The 2013 regulations designate which domestic works are those designated electrical works. No fetched statutory instrument sets a numeric cross-section.
Regulation 2 says: “These Regulations come into operation on 1 October 2013”. The preamble records that a draft of the regulations was laid before each House of the Oireachtas and a resolution approving the draft was passed. That draft-and-resolution step is not the operation date. The instrument was sealed on 18 July 2013, and notice was published in Iris Oifigiúil of 19th July 2013.
NSAI says: “All ETCI documents have been WITHDRAWN since 31st July 2022.” The table lists ET 101:2008+A1 and A2, National Rules for Electrical Installations, withdrawn 31/07/2022. The whole listed ET 101 documents are withdrawn, not one section. The fetched text of S.I. No. 264/2013 defines “National Rules for Electrical Installations” as “the current issue of the rules which are prepared by the Electro Technical Council of Ireland (or other body as the case may be)”. That definition does not set a conductor cross-section, and it does not name I.S. 10101. The CRU page says Safe Electric is “Assessing RECs to make sure they are working to national safety standards and the National Rules for Electrical Installations (I.S.10101).” That names the NSAI standard as what registered electrical contractors are assessed against. It does not call I.S. 10101 this statutory instrument.
