A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that quickly breaks an electrical circuit with leakage current to ground. It is to protect equipment and to reduce the risk of serious harm from an ongoing electric shock. … Se mer RCDs are designed to disconnect the circuit if there is a leakage current. In their first implementation in the 1950s, power companies used them to prevent electricity theft where consumers grounded returning circuits rather than … Se mer The diagram depicts the internal mechanism of a residual-current device (RCD). The device is designed to be wired in-line in an appliance power cord. It is rated to carry a … Se mer RCDs can be tested with a built-in test button to confirm functionality on a regular basis. RCDs may not operate correctly if wired improperly, so they are generally tested by the installer. … Se mer Electrical plugs with incorporated RCD are sometimes installed on appliances that might be considered to pose a particular safety hazard, for example long extension leads, which might be … Se mer A pure RCD will detect imbalance in the currents of the supply and return conductors of a circuit. But it cannot protect against overload or short circuit like a fuse or a miniature … Se mer Differences in disconnection actions Major differences exist regarding the manner in which an RCD-unit will act to disconnect the power … Se mer A residual-current circuit breaker cannot remove all risk of electric shock or fire. In particular, an RCD alone will not detect overload conditions, phase-to-neutral short circuits or phase-to-phase short circuits (see three-phase electric power). Over-current protection ( Se mer Nettet2. A type. A type RCDs are not sensitive to impulsive currents up to a peak of 250 A (8/20 waveform). They are particularly suitable for protecting systems in which the user equipment has electronic devices for rectifying the current or phase-cutting adjustment of a physical quantity (speed temperature, light intensity, etc.) supplied directly by the mains …
