Outdoor home-entry power-off electric leakage indicating device

The invention belongs to the technical field of electrical variable measurement, particularly relates to an outdoor home-entry power-off electric leakage indicating device, and aims to solve the problem that an existing electric leakage indicating device cannot determine whether secondary conduction occurs in an electric brake or not after power off, and provides the following scheme that the outdoor home-entry power-off electric leakage indicating device comprises a bottom layer shell of a groove-shaped structure on the whole; a fixing batten communicated with the left side and the right side is fixed close to the lower portion of the groove bottom of the bottom layer shell, a current transformer is fixed close to the top end of the inner wall of the back face of the bottom layer shell, an insulation fixing sleeve is fixed in a through hole of the current transformer, and a first terminal and a second terminal are embedded in the upper end and the lower end of the bottom layer shell respectively.
