What can happen if the wire in an irrigation system is undersized?

Using undersized wire in an irrigation system can lead to increased voltage drop along the wire. This drop in voltage can cause the electrical current supplied to various components, such as valves and pumps, to be lower than required for their optimal operation. As a result, the valves may not open or close properly, leading to potential malfunctions or erratic behavior in the irrigation system. Insufficient voltage can cause the components to operate inefficiently or may even prevent them from operating altogether. Therefore, ensuring that the wire gauge is appropriate for the system’s requirements is crucial for maintaining reliable performance and functionality.
