Upcoming Courses 

14th September 2018 | London - Overview of IET Wiring Regulations - A1638

7th December 2018 | London - Overview of IET Wiring Regulations - A1676

Course Content

This course offers a "guided tour" of BS 7671:2008 incorporating amendment 1 : 2011, amendment 2: 2013 and, significantly, amendment 3: 2015 which will affect all new installations from 1 July 2015, as well as the 17th edition.

The course provides information on the background, the history and some of the theoretical concepts behind the standard. Starting with a synopsis of the history of the regulations, the delegate will learn some of the underlying principles of electrical installation theory and why the need for prescriptive regulations is necessary.

The trainer will take delegates through each part of the regulations section by section, describing key points of interest, importance and/or debate.

The following key principles are considered:

  • Cable sizing
  • Protection against overload and fault current
  • Protection against electric shock
  • Earthing and bonding
  • Isolation and switching
  • Selection and erection of equipment
  • Special installations (see below)
  • Inspection and testing

Challenging environments and the particular risks associated with locations such as bathrooms, swimming pools and other non standard installations are explored, although only areas relevant to industrial and commercial application are seriously considered.
Electrical protection and fault levels are also covered with demonstrative examples.

Parameters and factors affecting cable sizing and selection of wiring systems are introduced within the context of the regulations and again, demonstrative examples are used to illustrate the importance of correct design.

Amendment 3 will be fully incorporated into this course and is expected to affect but are not limited to the following areas:

  • Consumer units (to come into effect January 2016)
  • Wiring in escape routes
  • Changes to earth fault loop impedances for all protective devices 
  • Updated EIC and EICR forms
  • Changes to definitions throughout the Regulations

Learning Outcomes

  • Understanding and comprehension of the important role  wiring regulations have had throughout the electrical industry
  • Understanding the limits of application and where current edition sits within the UK regulatory framework 
  • Appreciation of some of the theory behind the regulations and importance of compliance in terms of electrical safety
  • Knowledge of the geography of the document and how to use the regulations and associated literature

Who Should Attend

  • Electrical engineers of all grades (from either a consultancy or contracting background
  • Building services engineers (who may specialise in fields other than electrical engineering)
  • Property managers
  • Building surveyors 
  • Architects

And anyone involved in the build process and the high level procurement of electrical installation design or services would find this course useful as a means to increase their understanding and improve their awareness of the design and installation requirements of electrical services.
