Which of the following would likely not result from a ground fault?

The correct answer is indeed that enhanced security for devices is unlikely to result from a ground fault. A ground fault typically occurs when there is an unintended path between the power source and the ground, often due to insulation failure or other faults in the electrical system.

In such cases, the consequences typically revolve around safety, performance, and equipment integrity. For instance, system shutdowns can occur as protective measures against potential hazards caused by ground faults, which may include short circuits or shock risks. Additionally, increased noise in audio systems can happen as a result of grounding issues, leading to hum or interference in the audio signal, which is a common challenge in AV installations. Equipment malfunctions can also stem from ground faults, as the electrical disturbances can cause devices to operate improperly or even fail completely.

In contrast, enhanced security for devices does not correlate to ground faults. Rather, ground faults are primarily safety hazards that can compromise the effectiveness and reliability of AV systems, making it imperative to ensure proper grounding practices are followed to avoid such faults.
