When calculating feeder sizes, what factor should be considered for voltage drop?

When calculating feeder sizes, considering the length of the feeder run is crucial for accurately assessing voltage drop. Voltage drop occurs as electrical current travels through conductors; the further the distance the current must travel, the more resistance it encounters, thus leading to a loss of voltage.

As the length of the feeder increases, the resistance of the conductor also increases, which can result in a more significant drop in voltage. To ensure that the electrical equipment receives adequate voltage, it is essential to calculate the feeder size based on the feeder run length. This helps maintain efficiency and performance in the electrical system, making it vital for proper load calculations.

While type of conductor material, load type, and ambient temperature all play roles in electrical performance, they do not directly address the critical aspect of how distance affects voltage drop. Understanding the relationship between feeder length and voltage drop helps ensure compliance with electrical codes and optimal system performance.
