A person's body resistance in the waterpark, public bath and similar places is lower than any other places due to effect of water. So low voltage may create a shock hazard for the human body in case of leakage or fault currents from lighting unit etc. We researched the related regulations these are internal standards, NEC, IEC and investigated the actual conditions for the prevention of electrical shock due to lighting units in the waterpark, public bath and similar places. So we could present actual facilities's problems and solutions

A person's body resistance in the waterpark, public bath and similar places is much lower than any other places due to effect of water. So low voltage may create a shock hazard for the human body in case of leakage or fault currents from lighting unit etc. We researched the related regulations which are internal standards, NEC, IEC and investigated the actual conditions for the prevention of electric shock due to lighting units in the waterpark, public bath and similar places. As a results internal standard is obscure as compared with NEC, IEC which is the limit of application and distinction of environment condition. And then internal standard's using voltage is higher than NEC, IEC in filed of water. Studies show that internal standard should be revision that raise the installation height of lighting unit, mark IP level surface of lighting unit and limit using voltage to line-to-line voltage

This paper presents the evaluation electric shock risk in water so that we made and designed a bathtub which is the same size in real public bath. and then we did an experiment, provided of electric leakage in various conditions so, we measured how to form an electric gradient and knew the electric gradient is formed variously under exposed conductor in water. also we made certain that electric shock risk is down if we insert an insulated pipe in bathtub pipe which is prevent from being formed the electric field sharply.
