The invention discloses an earth box capable of achieving live-line switching. The earth box comprises a first changeover switch, a second changeover switch and a third changeover switch, wherein the first changeover switch and the second changeover switch are double-throw switches and comprise first channels and second channels; the third changeover switch is a single-throw switch; one end of the third changeover switch is coupled to an earth wire inlet port of an external cable sheath and the other end is coupled to one end of the second channel of the first changeover switch, is coupled to a first cable sheath protector and then is grounded; the second changeover switch is coupled to a second cable sheath protector and then is grounded; and the number of voltage grades of the first cable sheath protector is different from that of the second cable sheath protector. According to the earth box capable of achieving live-line switching disclosed by the invention, through the arrangement of the first changeover switch, the second changeover switch, the third changeover switch, the first cable sheath protector and the second cable sheath protector, the voltage grade effect of the earth box capable of achieving live-line switching can be effectively achieved.
