  • Understanding, interpreting and applying technical content for electrical/instruments application design.
  • Employment/Sponsorship Letter. This will be requested in support of the candidates’ technical qualifications, career history and current technical role.

Course Overview

The CompEx Ex12 course covers the application design and selection of electrical equipment, along with the requirements of IEC 60079-14: Electrical installations design, selection and erection.

The course fully addresses the designer’s requirements to the new 2014 Installation and Inspection Standards.The course is intended to give an in-depth awareness to the candidate with regard to explosive atmospheres formed by gases, vapours, mists and some insight to combustible dusts. It covers the application design and selection of electrical equipment for use in explosive atmospheres.  As the persons attending the course are Designers/Engineers or at an equivalent senior level, the course covers the basic and more in depth elements of the installation requirements from a theoretical viewpoint.

All presentation material is in Microsoft PowerPoint. Electronic handouts are given to candidates and are intended to be used as an aide-memoir tool in the future. (Hard copies are available at a cost)
