What is the recommended method to compensate for voltage drop on long wire runs?

Using larger wire to compensate for voltage drop on long wire runs is a sound method grounded in electrical principles. When electrical current travels through a conductor, it encounters resistance that can lead to a voltage drop. This drop is more pronounced with longer wire runs and smaller gauge wires, which have higher resistance.

Larger gauge wire has a lower resistance per unit length, which means that it allows current to flow more easily and minimizes voltage drop over long distances. The increased diameter of the wire helps maintain the voltage level at the load end, ensuring that the electrical devices receive adequate voltage for proper operation.

While other methods such as increasing voltage at the source or adding transformers can also be used to address voltage drop, they may introduce additional complexity, cost, or potential for inefficiencies. In many practical scenarios, simply selecting a larger wire is the most straightforward and effective solution to mitigate voltage drop issues on lengthy wire runs.
