Abstract
A method and device for monitoring a test interval for a residual current protective device includes measuring an operating time of the residual current protective device, triggering an alarm report if the measured operating time exceeds an operating time limit, and restarting the operating time measurement upon detection of a trigger process of the residual current protective device. In an embodiment of the invention, a time period is measured independent of the operating time of the residual current protective device.
