Residual Current. Noun an electric current which flows briefly in a circuit after the voltage is reduced to zero due to the momentum of the charge carriers. A residual current device rcd residual current circuit breaker rccb or ground fault circuit interrupter gfci is a device that quickly breaks an electrical circuit to prevent serious harm from an ongoing electric shock.
The tripping time is such as to minimise the risk to human life. Analysis of the blocked states in the presence of maltohexaose shows that the residual current per monomer is zero within the accuracy of our measurements. Therefore unless the residual current does not surpass the limit the rccb will disconnect the circuit.
The main application is to prevent electrocution but rcds can also be used to protect equipment especially against fire.

Noun an electric current which flows briefly in a circuit after the voltage is reduced to zero due to the momentum of the charge carriers. Residual current circuit breaker rccb is a switch that can act automatically when the leakage current in the circuit exceeds a predetermined value. The tripping time is such as to minimise the risk to human life.
