Disclosed is a device capable of preventing a short circuit even in the event of flooding. A terminal polarity fixing unit is disposed between an input terminal unit and an output terminal unit such that a first output terminal and a second output terminal are electrically connected to a neutral terminal and to a phase voltage terminal, respectively, all the time, regardless of how first and second input terminals are paired with the phase voltage terminal and the neutral terminal of an alternating-current outlet. First and second connecting terminals are electrically insulated from each other and spaced apart from each other while being exposed to one side of a body unit of a connecting terminal block made from an insulating body, and electrically connect the first and second output terminals to a load. A short circuit prevention conductor is connected to the first connecting terminal, which is in turn connected to the neutral terminal but is not connected to the second connecting terminal, and is arranged in the vicinity of the second connecting terminal so as to surround at least a portion of the side of the connecting terminal block, at least a portion of the upper portion of the connecting terminal block, and at least a portion of each of the side and upper parts of the connecting terminal block. When the connecting terminal block is flooded, the electric current flowing out of the second connecting terminal flows into the short circuit prevention conductor via the water, and an electric current sufficient for causing an electric shock does not flow to other sites. |
