The candidates are encouraged to raise queries both during and at any time after attending the seminar. They are also encouraged to bring with them any issues that they may have to this course.

By the end of this course delegates will be able to:

• A better understanding of commissioning procedures
• A better understanding of troubleshooting procedures
• An improved capability in the use of test equipment
• A better understanding of failure modes and failure analysis
• A refreshed awareness of electrical safety concerns

This seminar is intended for Electrical Engineers, Electrical Supervisors and Electrical Technicians engaged in the commissioning, testing, start-up, troubleshooting, maintenance and repair of Electrical Equipment and Control Systems. Because the methods and examples are generic, personnel from all industries will benefit. Participants need no specific requirements other than good understanding of electricity and magnetism and some relevant experience
