3rd Amendment Workshop

Nationwide course ideal for 17th Edition electricians and electrical contractors to get up-to-date with the new 3rd Amendment to the BS7671:2008.

As of July 2015, all people involved with installing, constructing and inspecting/testing electrical installations must comply with the rules and regulations outlined in the IET Wiring Regulations 17th Edition: Amendment 3.

Several changes were made to the IET Wiring Regulations under the 3rd Amendment (2015) – to help you to understand these changes and how they may affect your work on a daily basis, PASS is now running regular 3rd amendment workshops.

Course Suitability

This workshop is best suited to those with an existing 17th edition qualification who want to gain an understanding of how the changes made under Amendment 3 affect them.

There are no formal requirements for this workshop. Anyone can attend, but a working knowledge of the previous 17th edition regulations would be beneficial.

  • Why the regulations are updated
  • Another change to the numbering system!
