The invention relates to an electric leakage breaker, and especially relates to an electric leakage breaker internal testing device power taking structure; the electric leakage breaker testing device power taking structure also comprises a power taking column or power taking spring, and push rod arranged on an electric leakage breaker housing in a slide manner; one end of the push rod is matched with a hinge swing end of an N-electrode movable contact, and the other end is matched with a first torsion arm of a torsion spring; the power taking column or power taking spring are electrically connected with an L electrode movable contact or a tension spring; when the N electrode movable contact is closed, the first torsion arm pushes the push rod to move, so the first torsion arm is electrically connected with the power taking column or the power taking spring; when the N-electrode movable contact is open, the N-electrode movable contact hinge swing end pushes the push rod to move. When a product is in an open state or released, the novel electric leakage breaker internal testing device power taking structure has no L-phase power supply for a circuit board and the testing device.
