This book covers the fundamentals of electrical system design by applying Vosts from Dolphins software. Volts is a software program that is used to create electrical systems through the use of an intuitive interface that accommodates the needs of electricians, designers, code inspectors, and engineers. Volts improves the efficiency of the electrical design process and performs accurate calculations through the use of buttons, data entry boxes, and dropdown lists. Calculations correspond to industry requirements and are used to determine system protection, conductor size, conduit size, voltage drops, and more. The text focuses on the most common Volts commands and addresses the concepts required for efficiently creating electrical systems. An answer key is also available.
