Product Title:TRICONEX 3504E Digital input card
Detailed product introduction:
To prevent this situation from arising, the motor frame must be grounded via the equipment grounding conductor (green wire). The resistance of the fault path must be low enough to permit the fault current to trip the overload protector and interrupt the fault. If the resistance of the fault path is too large, the fault current will not be enough to trip the overload protectors. Thus to minimize both shock and fire hazards, the resistance of the fault path must be as low as possible. However, the fault protection subsystem normally does not depend on the earth electrode subsystem to trip overcurrent devices. The fault current normally flows through the green wire (grounding conductor) to the source side of the first service disconnect where the green wire and the neutral are tied together.
