In what way does proper grounding improve safety in motor operations?

Proper grounding plays a critical role in enhancing safety during motor operations by directing fault currents safely away from personnel. When a fault occurs, such as a short circuit or insulation failure, the electrical current can take unintended paths, potentially leading to hazardous situations for operators and equipment. Grounding provides a low-resistance pathway for these fault currents to flow safely into the earth. This significantly reduces the risk of electric shock or electrocution for individuals working with or near the motor.

In addition to protecting personnel, effective grounding also helps to prevent equipment damage by allowing protective devices, like circuit breakers or fuses, to operate correctly. When a fault occurs and is directed to ground, these devices can quickly isolate the problem, minimizing the risk of further incidents.

While other choices mention aspects related to motor operation, such as wear and tear, speed maintenance, and efficiency, they do not address the primary protective function grounding serves in ensuring the safety of personnel and equipment during motor operations.
