Abstract： This article mainly discusses the causes of leakage of household appliances. It analyzes the leakage protection function of RCBO in household distribution circuits， and it is found that the electronic RCBO  in common distribution circuits in China has the problem of insufficient leakage protection. In view of these problems， two solutions are proposed， which are the use of self-recovery over-undervoltage protection apparatus （OUPA） and electromagnetic RCBO.

Key Words： Household distribution circuits; Leakage; OUPA; Electromagnetic RCBO
