This book presents AC and DC motor control, relay logic and related electrical code requirements in terms that relate to on-the-job situations. The theoretical foundations are presented and a logical approach provides the reader with thorough background in the requirements of the electrical code. It discusses application of the code requirements and aims to provide a detailed study of full voltage motor starting, circuits and equipment, time-delay and transition. Also covered in the book are design, installation and troubleshooting. A working knowledge of basic electrical theory and terminology is required, but only a minimal knowledge of mathematical background. Summary questions and multiple-choice problems are included.
