Its a Residual Current Device. Its a safety device that measures the imbalance of current between the conductors in the cable.

A residual current device (RCD), or residual current circuit breaker (RCCB), is an electrical wiring device that disconnects a circuit whenever it detects that the flow of current is not balanced between the phase ("hot") conductor and the neutral conductor. The presumption is that such an imbalance may represent current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A shock, possibly lethal, is likely to result from these conditions; RCDs are designed to disconnect quickly enough to prevent such shocks.
In the United States and Canada, a residual current device is also known as a Ground Fault Circuit Interrupter (GFCI) or an Appliance Leakage Current Interrupter (ALCI).

hey richard_beckham2001, the first guy who answered this:
wut you are talking about is an RLC circuit
R - resistor
L - inductor (coil)
C - capacitance
but anyways RCD does stand for residual current device. heres sum info on these devices

I think it's Residual Charge Device and it's usually attached to Lawn Mowers and Drills.
It's the handy piece of kit which stops you from electrocuting yourself when you mow over / cut through the power cable...
