From the sensor to the ground fault relay, wires should not exceed what length?

The guideline for the maximum length of wires from the sensor to the ground fault relay is critical for ensuring the proper functioning and sensitivity of the ground fault protection system. Lengthy wiring can introduce resistance and potential issues such as signal degradation, which may lead to delayed or incorrect responses from the relay.

The standard maximum length of 25 feet is established to maintain the integrity of the signal transmitted between the sensor and the ground fault relay. This shorter distance helps ensure that the relay can accurately and promptly detect any ground faults, which is vital for preventing electrical hazards and protecting equipment and personnel. By keeping this distance to 25 feet, the system can operate effectively and with the desired level of safety.
