On long runs, it may be necessary to ____ to compensate for voltage drop.
A) decrease the branch circuit length
B) apply an approved voltage amplifier
C) boost supply influx
D) increase the branch-circuit conductor's size

Question

Quizplus · Accepted Answer

As voltage travels a long distance through a conductor, there is a loss of voltage due to the resistance of the conductor. To compensate for this voltage drop, the branch-circuit conductor's size needs to be increased to reduce the resistance and allow more current flow, which will result in less voltage drop across the conductor. Therefore, increasing the branch-circuit conductor's size is the best option to compensate for voltage drop on long runs.
