A switch box of a prop for protecting a distribution board is provided to confirm a connection state of an input terminal and an input wire by checking the light of a first lamp by operating a first switch. An external lead-in wire is inserted into a housing(100). A remaining wire reception box(B) keeps the remaining part of a lead-in wire and is mounted in the housing. The input wire is drawn out from the remaining wire reception box. A case(210) has an outlet(212) into which an output wire is inserted and an inlet(211) into which the input wire is inserted. A circuit break(220) is installed inside the case and includes input and output terminals. The input and output wires penetrating through the inlet and outlet are electrically connected to the input and output terminals. A first confirming unit(300) is installed in a housing and is composed of a first lamp connected in parallel to the input terminal and a first switch(320) which is connected to the first lamp and controls the blinking of the first lamp. A second confirming unit(400) is installed in a housing and is composed of a second lamp(410) connected in parallel to the input terminal and a second switch(420) which is connected to the first lamp and controls the blinking of the first lamp. |
