What aspect is crucial when selecting the conductor sizes for feeders?

Selecting the proper conductor sizes for feeders is fundamentally tied to ensuring that voltage drop remains within acceptable limits. Voltage drop affects the performance of electrical systems by influencing the voltage level delivered to equipment and devices. If the drop is too significant, it can lead to inefficiencies and potential damage to electrical equipment due to insufficient voltage.

When considering voltage drop, calculations are conducted based on several factors, including the length of the run (which affects resistance), the load current, and the type of conductor used. It is essential to accommodate these calculations during the design phase to ensure that the electrical system operates reliably and efficiently, as well as to meet applicable codes and standards.

While factors like environmental impact, cost of materials, and length of installation may influence the overall project planning and design decisions, the foremost priority in selecting conductor sizes is to adequately manage voltage drop to maintain system integrity and performance.
