Etci national rules for electrical installations

Much of what is discussed in this chapter is covered in greater detail in the subsequent chapters.Д¬hapter 2 provides definitions of the various terms used throughout the standard. It outlines the scope and fundamental principles. The following is a brief summary of what is contained in each chapter along with references to the most significant changes:Д¬hapter 0В provides a brief outline of the standard and a list of normative references used throughout.В The bibliography also includes 182 references to various international standards.Д¬hapter 1 is a relatively short chapter. 74% of the standard is taken up by Chapters 4,5 & 7.ДЇigure 2:В Percentage of each Chapter of IS 10101 (Sample illustration from Guidebook) The new Standard comprises eight Chapters, 0 to 7 as listed below and a new standalone Part 8 which deals with energy efficiency. It now contains a total of 764 pages compared 352 pages of the 4 thВ Edition and to a mere 76 pages in the 1 stВ Edition Outline of the Standard The new standard has significantly more content than the previous editions of the Wiring Rules. Chapter 8: Energy Efficiency вЂ“ New Section.Part 730 Onshore Units for Inland Navigation Vessels вЂ“ New Section.Part 710 Installations in Medical Locations вЂ“ Multiple changes.Part 722 Supplies for Electric Vehicles вЂ“ New Section.Chapter 6 - Model certificates have now been removed.534 - Selection of Surge Protection Devices (SPDs) вЂ“ significant changes.

Clause 531.3.3 Type AC RCDs are no longer recommended in new installations.

Clause 527 - Cables must now be rated to Class Dca s2, d2, a2 in accordance with EN50575.

Clause 512.1.5 - Compliance with the Electromagnetic Compatibility (EMC) Directive 2014/30/EU.

Clause 421.7 - Arc Fault Detection Devices (AFDDs) are now recommended for circuits installed in locations with particular risk.

Clause 411.3.4 - (RCDs) are now required to be installed on lighting circuits in domestic premises.

At the very least worked examples should be provided in the future.

Instead a formula is provided for calculating the voltage drop. The old volt drop tables have been removed. Other changes are driven by climate action policy and associated emerging technologies such as charging points for electric vehicles and PV systems.ДЄnother big change is that purchasers of the new standard are now given access to an on-line version which allows searching of the document using keywords. Some of these relate to new or revised protective measures.ДЇor example, the use of RCDs for lighting circuits in domestic premises, the requirements for arc fault detection devices (AFDDs) and surge protection devices (SPDs). There are many important changes to the new standard as summarised below. This is now in its 18 th Edition Changes in the new Standard Is worth notingВ that the UK maintained the edition number when the '16 th Edition 'В IEE Regs became British Standard BS7671. It is unclear whether the new standard will be called the '5 th Edition of the Wiring Rules'В or the '1 st Edition of IS10101'. In fact when I started my apprenticeship in 1978 the 14 th Edition of the Regs, was part of the curriculum for the electrical apprenticeship courses in Ireland well into the 1990s due to the prevalence of City and Guilds courses here. This book was simply referred to on both sides of the water asВ 'The Regs'. However the unofficial 'Wiring Rules'В in Ireland for many years wereВ 'The Regulations for the Electrical Equipment of Buildings'В as published by the Institution of Electrical Engineers (IEE) in the UK. The first edition of the 'Wiring Rules'В as we now know them was published in 1976 by the ETCI. The diagram below shows the evolution of the Wiring Rules in Ireland from the mid-1960s to the present day.ДЇigure 1:В Evolution of the Wiring Rules in Ireland (Sample illustration from Guidebook)Д®T 101:2008 was the fourth edition of the Wiring Rules to be published. After more than 12В years in use, the National Rules for Electrical Installations ET101:2008 haveВ been replaced with the new NSAI publication ISВ 10101:2020, writes Brendan Dervan.
