What is the maximum wire length from the sensor to the ground fault relay recommended?

The maximum wire length from the sensor to the ground fault relay is recommended to be 25 feet because longer distances can lead to increased resistance and potential signal loss. When the wire length exceeds this recommended limit, the effectiveness of the ground fault detection can be compromised, leading to delays in responding to ground faults. The sensor is designed to accurately detect variations in current, and any extensive runs may introduce noise or other interferences, which can result in false readings or failure to trip during actual fault conditions.

This parameter is crucial for maintaining the sensitivity and reliability of the ground fault protection system. Staying within the 25-foot limit ensures that the ground fault relay receives a clear and accurate signal from the sensor, thereby enhancing the overall safety and efficiency of the electrical system.
