With the increasing interest in green energy, there is a constant demand for renewable energy and DC power systems. DC systems are known to be an efficient system due to energy loss reduction and efficient control, and safer than AC systems in terms of electric shock. Therefore, research and demonstration projects are being carried out. However, those related to electrical safety and installation regulations are insufficient. As a result, the commercialization of related appliances and equipment is delayed. One of them, the lack of installation regulations for DC-RCDs, whose installation is almost mandatory under the Korea Electric Code(KEC), hinders the expansion of DC buildings and reduces the electrical safety of those who directly use electricity. In order to improve this situation, this paper, based on International Electronical Commission(IEC), analysed the risk of human electric shock due to the occurrence of DC leakage and ground fault, and proposed the minimum specification of DC leakage current protect devices for low-voltage electrical consumers according to the circumstances and to the technology that can be applied to existing equipment.
