After a modification, you notice low voltage to a motor. What is the solution if the disconnect was moved 30' away?

When a disconnect is moved a significant distance away from a motor, as in this case where it was moved 30 feet, the resistance in the wiring can lead to a voltage drop. This is particularly important in electrical systems, as increased distance can cause a reduction in voltage delivered to the motor, potentially impacting its performance.

Increasing the wire size is an effective solution because larger conductors have lower resistance, which reduces the voltage drop over longer distances. By using thicker wires, the current can travel more efficiently from the power source to the motor without significant loss in voltage. This can restore the voltage levels necessary for optimal motor operation.

Other considerations, such as replacing the motor, checking for damage, or installing a voltage regulator, address symptoms or alternative issues but do not directly tackle the root cause of voltage drop related to wire size and distance. Thus, increasing the wire size directly addresses the problem of low voltage due to the physical changes made in the electrical setup.
