These devices, called ground check monitors, are required by coal mine electrical regulations to continuously monitor trailing cable ground wire continuity. When a ground wire is broken, the monitor trips the circuit breaker feeding the trailing cable thus deenergizing the machine and preventing the machine frame from becoming energized.
