The invention relates to a lightning arrester live-line monitoring junction box, which comprises a box body and wire connecting terminals. An insulating plate is fixedly installed in the box body. Thefour wire connecting terminals are fixedly installed on the insulating plate, wherein three of the terminals are phase-A, phase-B and phase-C wire connecting terminals, and the other one is a groundwire connecting terminal. Two wiring holes are formed in the bottom of the box body, one wiring hole is used for leading a lower lead of a lightning arrester into the box body and connecting the leadto the wire connecting terminals, and the other wiring hole is used for leading a resistive current and total current tester lead of the lightning arrester into the box body and connecting the lead tothe wire connecting terminals. The lightning arrester live-line monitoring junction box is simple in principle and convenient to install, does not influence normal work of an original lightning arrester, and does not damage the
