[1] Residual Current Device. I am not sure if
that trem crosses the Pond,
it's a device that detects an imbalance of current in the live and
neutral wires, indicating a leak to earth somewhere, agd turns off the
supply if that imbalance is greater than a certain (small, perahps 30mA)
value.
Called a GFI (Ground Fault Interrupter) here.
Now often GCFI or GFCI ("circuit" needed to be mentioned)
