    When is a residual current device required?

    Electricians

    In what scenarios would a residual current device be necessary? What is the overall purpose of this device and is it ever legally required?

    "Required for all domestic consumer units that have got circuits feeding socket outlets and lighting circuits.
    For the purpose of protecting human life from fatal electrical shock in the event of a fault condition occurring in the electrical installation.
    Very useful device."

    "Every Circuit in a house these days should be protected by a Residual Current Device (RCD).
    Most fuseboards should have twin RCD to meet with current wiring regulations."
