Under normal conditions, the current entering through the phase conductor should be equal to the current exiting through the neutral conductor.\u003c\/p\u003e\n\u003cp\u003eCurrent Difference: If there is a difference (residual current), it indicates that a portion of the current is flowing to earth, possibly through a person's body or due to faulty insulation.\u003c\/p\u003e\n\u003cp\u003eMain Components:\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eToroidal Transformer: A toroidal transformer surrounds the phase and neutral conductors.
