What is the required warning threshold for resistance in VAC according to ground fault monitoring?

The required warning threshold for resistance in VAC according to ground fault monitoring is 1000 ohms/VAC. This standard is put in place to ensure that any potential ground faults are detected well before they pose a significant danger.

In the context of ground fault monitoring, a resistance threshold of 1000 ohms/VAC indicates that if the resistance drops below this value, it signifies a more serious fault condition, which could lead to electrical shock or equipment damage. This level of resistance is considered safe for the operation of electrical systems, as it allows for effective detection and intervention prior to hazardous conditions occurring.

Understanding this threshold is crucial for maintaining the safety and functionality of electrical systems, especially in marine environments where electrical faults can have dire consequences.
