An electric piping device for water leakage prevention is provided to prevent moisture or water from flowing through a lower cable pipe by installing an upper part of the lower cable pipe protrusively inside the water leakage prevention. An electric piping device for water leakage prevention includes a water leakage prevention box(30), and a sealing unit. Lower/upper penetration holes(31,32) are formed on a central part of a lower plane and an upper plane of the water leakage prevention box. A lower part of an upper cable pipe which receives a cable is closely adhered to the upper penetration hole. An upper part of a lower cable pipe which receives the cable is protrusively installed at a predetermined height through the lower penetration hole. A water ejection hole which is coupled to a water ejection pipe and is closed or opened by a water ejection cork is formed on a lower plane of the water leakage prevention box. The sealing unit seals an opened upper part of the lower cable pipe. |
