Abstract:
A system is described herein, including an activation circuit configured to generate a signal indicative of an alarm condition. A residual current device trigger circuit is coupled to the activation circuit and a residual current device. The residual current device trigger circuit is configured to provide a simulated earth leakage current condition to trigger the residual current device on receiving the signal indicative of the alarm condition.
