Electrical Drawings and Control Circuits

Introduction
Electrical Drawings and Control Circuits training seminar begin with the development of various relevant drawings and symbols representing devices that are vital in all electrical installation to ensure continuity and efficient operations. The primary and fundamental tool for troubleshooting and maintenance of an electrical installation is to understand and interpret electrical drawings and ladder diagrams.
Electrical symbols, schematic, and wiring diagrams facilitate the operations of the electrical installation equipment. This programmer will cover all these aspects of electrical blueprint reading and the tracing of circuits.
OBJECTIVES
By the end of this training course, participants will be able to:
• Describe the various types of electrical drawings
• Appreciate the importance of single line diagrams
• Analyses the various electrical ladder drawings
• Explain the operation of the electrical equipment using wiring and schematic diagrams
• Recognize the symbols in electrical drawings
