Overview of a testing arrangement and some quick tests to demonstrate the effect of pulsed DC on a type AC RCD.
The black box is used to create a fault to earth, equivalent to the insulation in the heater being defective. Fault current shown on the multimeter in mA.
This test places a single diode in series with the heater, effectively running it on half power on pulses of DC at 50Hz. This arrangement was commonly used in heaters to provide a full/half power option with a single switch.
