Low-voltage switchgear and controlgear assemblies - Distribution boards intended to be operated by ordinary persons (DBO) Ingestion-build-63114 PD CLC IEC/TR 62453-52-31 onWhat is this standard about? This part of IEC 61439 defines the specific requirements for distribution boards intended to be operated by ordinary persons (DBO). DBOs have the following criteria: intended to be operated by ordinary persons (e. g. switching operations and replacing fuse links), e. g. in domestic (household) applications; outgoing circuits contain protective devices, intended to be operated by ordinary persons, complying e. g. with IEC
