Electrical Principles and Schematics

Summary

This course will provide participants with; an appreciation of electrical engineering principles; the knowledge to manage electrical staff; the ability to converse with electrical engineers and technicians and an understanding of their responsibilities under the Electricity at Work Regulations.

It will also provide non-electrical personnel an understanding of electrical symbols and drawings as used in typical electrical schematic diagrams.

How will I benefit?

After the course you will be able to:

  • Understand the basic concepts of electrical engineering
  • Appreciate their responsibilities under current health and safety legislation
  • Understand the terminology used in electrical engineering.
  • Appreciate the dangers and safety procedures associated with electrical engineering.
  • Effectively converse on electrical topics with electrical personal
  • Develop your own understanding of electrical systems in your work environment
  • Interpret basic block diagrams, layout diagrams and electrical drawings
  • Identify key symbols used in typical electrical engineering diagrams.
  • Identify selected components and understand how they function within that circuit
  • Understand the techniques used in the layout of a typical set of electrical drawings.
  • Effectively converse on electrical schematics with electrical personnel
  • Develop your own understanding of electrical diagrams in your work environment

Who should attend?

This course is particularly suited to:
