SUMMARY
The discussion centers on the functionality of Residual Current Devices (RCDs) in two scenarios: connecting a 2kW heater to an external RCD using hot and neutral wires from a 230V AC socket, and using an AC floating supply instead of the standard hot and neutral wires. In both cases, the RCD will trip if there is a current imbalance, as it detects differences in the currents passing through its transformer core. This is due to the principle that equal and opposite currents cancel each other out, and any leakage fault will result in a secondary current that triggers the RCD.
