The invention discloses a power distribution box convenient for self-wiring of a user, and relates to the technical field of power equipment, comprising a box body, wherein the bottom of the box bodyis provided with a mounting hole, and a terminal for connecting the wire is arranged in the mounting hole. The terminal provided by the invention is detachably installed in the mounting hole of the power distribution box, which is convenient for the transformation and access of the line in the power distribution box in the place where the power supply lines of the old community are laid without specification. Pre-installation is performed using the terminal before the completion of the laying of the lines, so that the wiring port for the user is left in advance, and the user may automaticallyaccess and fix the line through the terminal, thereby avoiding the repeated installation of the installer, improving the work efficiency of the installer, and enabling self-wiring of the user to obtain real plug and play.
