The invention discloses an all-round leakage protection plug for monitoring the live detectability of a ground wire. A series loop comprising a current-limiting resistor and a monitoring switch is connected between an internal phase line contact circuit and zero line contact circuit of the all-round leakage protection plug, and the series loop passes through a ground wire live detection inductor. When the ground wire live detection inductor passed by the ground wire has a fault, an all-round leakage protector having a fault can be found in time before an electrical hazard happens through periodical detection by a monitoring circuit, thus the fault can be eliminated in time, and the happening of the electrical hazard can be avoided.
