Abstract
A surge protective system has a plinth for wiring and is connected between a plurality of line side wires and a ground wire. A plurality of surge protective devices (SPDs) and one surge detector are disposed in parallel and detachably fitted into and attached to the plinth. The plinth has a wiring metal fitting for connecting the plurality of SPDs and the one surge detector. When a lightning surge current enters into the surge protective system from the line side wires, the lightning surge current flows to the surge detector through the SPDs, a 1st plinth contact part in the wiring metal fitting, a connection part and a 2nd plinth contact part. The lightning surge current flowing to the surge detector is discharged to the ground through the ground wire.
