Working with electrical power


In this chapter, we look at electrical phenomena that affect the way we have to size our distribution cables—namely, line loss and electronic nonlinear loads. We will also discuss ways in which we measure and test electrical circuits, and deepen our understanding of the hazard of electrical shocks.

Let's begin with an overview of the factors that affect the size (or number) of conductors we use in our feeder cables, including phase conductors, neutral conductors, grounding wires, and system grounding conductors. Following this overview, we will look in greater detail at the specifics of voltage drop calculations, and the nature of nonlinear loads.
