To determine a reasonable minimum size for a neutral conductor, two types of loads must be considered-____.
A)fuses and circuit breakers
B)series and parallel
C)linear and nonlinear
D)motors and hermetic units

Question

Quizplus · Accepted Answer

Nonlinear and linear loads must be considered because they have different effects on the neutral conductor. Linear loads have a predictable, sinusoidal current draw, while nonlinear loads can cause harmonic currents that may increase the neutral current beyond the phase currents, affecting the sizing of the neutral conductor.
