    Residual-current device - Wikipedia

    • A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor. T… See more

    Application

    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 used outdoors, or garden equ… See more

    RCBO

    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 circuit breaker (MCB) does (except for … See more

    Typical design

    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 maximal current of 13 A and is desi… See more

    Common features and variations

    Major differences exist regarding the manner in which an RCD unit will act to disconnect the power to a circuit or appliance.
    There are four situations in which different types of R… See more

    Testing of correct operation

    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. By introducing a controlled f… See more

    Limitations

    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 … See more

  1. A Residual Current Device (RCD)12345is an electrical safety device that:
    • Interrupts an electrical circuit when there is leakage current to ground or current flowing to another powered conductor.
    • Prevents fatal electric shocks by cutting off power if you touch something live.
    • Provides protection against electrical fires.
    • Reduces the risk of electrical shock and fire.

  2. People also ask
    What is a residual current device (RCD)?
    The residual current device (rcd) is used to detect earth fault currents and to interrupt supply if an earth current flows. The main application is to prevent electrocution but RCDs can also be used to protect equipment, especially against fire. The earth fault currents that operate an rcd can range from 5mA up to many amperes.

    What is residual current device construction?
    The residual current device construction is composed of a current transformer. When there’s no leakage current, the magnetic fields generated by the current in the coils cancel out. However, when there is a leakage current, the fields generated by the live wire are disturbed, creating an imbalance.

    How does a residual current circuit breaker work?
    An RCD constantly monitors the current flowing through the live and neutral wires. If there is a difference between the two (known as leakage current), it means there is a problem somewhere in the circuit. The RCD will then switch off the power. Here is the working of a residual current circuit breaker explained.
