Cables Basics, Sizing & Selection

This course provides a practical understanding of electrical cables, their construction, types, applications, and selection criteria. Participants will learn about different cable materials, insulation types, voltage ratings, and cable configurations used in electrical systems. The course explains the fundamentals of cable sizing based on current-carrying capacity and operating conditions. It covers voltage drop calculations, short-circuit withstand capacity, and cable derating factors. Participants will understand how ambient temperature, installation method, grouping, and soil conditions affect cable selection. The course introduces cable sizing for power, control, instrumentation, and industrial applications. It also covers cable routing, installation practices, termination methods, and basic safety requirements. Relevant electrical standards and guidelines for cable selection and installation are discussed. Practical examples help participants evaluate cable specifications and choose suitable cable sizes for different applications. By the end of the course, participants will be able to make technically appropriate and reliable cable sizing and selection decisions.
