RCD Auto test

Residual Current Device RCD test

Auto RCD test does all the 4 tests twice, first at 1 of leakage ratting which was 30mA in this case, 5 X 30mA, 1.5 X 30mA it does it twice one for each side of the sine waves to measure the time it takes for the RCD device to trip, then in the last test it measures the amount of current it takes the Residual Current Device to disconnect at X1
