When calculating voltage drop, what factor is not considered?

In the context of calculating voltage drop, the size of the conduit is not a factor that affects the voltage drop itself. Voltage drop is primarily influenced by the electrical characteristics of the conductor involved in the circuit, which include the length of the run, the load current, and the conductor material.

The length of the run is important because the longer the distance the electricity has to travel, the greater the resistance encountered, leading to a higher voltage drop. Similarly, the load current plays a crucial role since a higher current flowing through the conductor will produce a greater voltage drop due to increased resistance. Additionally, the conductor material, such as copper or aluminum, has different resistivities which affect how easily electricity flows; this directly impacts the voltage drop as well.

The size of the conduit, however, does not have a direct impact on the voltage drop calculations. While the conduit size may influence the physical installation and heat dissipation of conductors, it does not alter the electrical properties affecting voltage drop.
