Practical Electrical Wiring Standards - IEE BS7671:2008+A1:2011 Edition

THE WORKSHOP

Internationally there is  steady progress towards alignment of the electrical wiring standards for low voltage installations. This is reflected in the IEC standard 60364, the European Harmonisation Document HD 60364 and the UK “IET Wiring Regulations” 17th edition, now also known as British Standard BS7671:2008+A1:2011, all of which share a common format.

Each day will be divided into sessions with practical examples of each of the concepts discussed. Delegates will have the opportunity to raise relevant issues and debate these in the sessions. 

The programme below sets out the various sessions and the content of the sessions. Delegates should note that the order of the sessions and content will be varied according to the needs of the delegates. Practical worked examples will be interspersed with the slides used. There is always time during coffee, lunch and tea breaks for further discussion.
