The Main Technical Changes in the Fourth Edition The following are some of the major changes: * Chapter 41 and Chapter 61: Fault loop impedance tripping times are all 0.4 sec, the 5 sec time applies only to special cases e.g. The international standard format followed up to now by the three editions of the National Rules has facilitated comparison with other national rules, and the 4th Edition will follow this more closely. Ireland has negotiated successfully for several SNCs, e.g.įor bonding and bathrooms. Where it is found necessary, countries are permitted to retain special requirements or 'Special National Conditions' (SNCs) which are justifiable on account of local conditions. Harmonisation of wiring rules in Europe has been a gradual process, and the 4th Edition represents a significant advance.
Ireland, represented by ETCI, has been an active member of CENELEC since 1973. The equivalent European organisation, CENELEC, uses the results of IEC as a basis for its deliberations and the work is carried out by CENELEC TC64, in which most European countries participate. The basic work on wiring rules is done in IEC TC64, the world-wide electrotechnical standards organisation. National Rules for Electrical Installations: (Reference to Chapters, Sections, Paragraphs, Tables and Annexes correspond to those contained in the National Rules. Appendix 62A of the ETCI’s 2008 National Rules for. 62.4 of the “National rules for Electrical Installations. * Changes and new developments in types of equipment, work practices and building practices. * New sections for areas hitherto not covered, for example marinas, amusement parks, photoelectric equipment and extra-low voltage lighting. * Technical changes resulting from decisions at international level (IEC and CENELEC) which necessitate the revision of existing rules. This has resulted in the following: * A new and radical restructuring of the rules, mainly in Part 4: Protection for Safety. The principle reason for producing the Fourth Edition is the progress on international harmonisation of wiring rules in IEC and CENELEC. To purchase the new Fourth Edition from the ETCI Publications Online Store. The Third Edition will not be valid after this date. New installations may be constructed to either the Third or Fourth Editions up to 30th September 2009. When this occurs, the parties involved should meet with the Company to resolve the changes, which shall be documented in writing.The National Rules for Electrical Installations, Fourth Edition, is now available for sale. Municipal and other building codes or special conditions may require installation changes. These rules document minimum Duquesne Light Company requirements. The customer shall notify and supply construction plans to the Division Office for any project near Company supply lines well in advance of planned construction.
These minimum clearances are specified in the National Electrical Code, the National Electrical Safety Code and some local building codes.
The rules require the installation of safe and adequate wiring and electrical equipment, which permits customers to enjoy the full benefits and convenience of safe electrical service.Ĭustomers shall ensure that new buildings, structures, additions, modifications and any other construction projects keep the minimum clearances required from existing Company supply lines. Since safety is our top priority, we’ve issued these rules for use by customers, builders, electrical contractors, architects, engineers, etc.
