How to size cable and protection devices

Course Summary

The purpose of this book is to cover the main rules that are used for sizing conductors, wiring systems and their electrical protection (against overloads, voltage drops, short-circuits and indirect contact) according to the parameters of the installation: physical (type of conductor, installation conditions, temperature, length of lines, etc.) and electrical (power, prospective short-circuit, operating currents, etc.). Examples of how they are determined are given for each parameter.

Course Objectives:

After learning this course, you will be able to

Determine Over-currents

Protect against Protection overloads and devices
