Electric of using in daily life is always exposed to risk of electrical fire and electric shock. Only degree of risk is different, there is no risk free electrical product. Generally, the higher voltage, the risk of electric shock is high. The much electric current, the risk of electrical fire is high. But, we can’t help using electric because of risk and we effort to reduce the risk of electrical fire and electric shock. This study deal with the fire prevention generated on heating equipment using SSR for current
