IEC 61439-3:2012 defines the specific requirements for distribution boards intended to be operated by ordinary persons (DBO). DBOs have the following criteria:
\n– intended to be operated by ordinary persons (e.g. switching operations and replacing fuse-links), e.g. in domestic (household) applications;
\n– outgoing circuits contain protective devices, intended to be operated by ordinary persons, complying e.g. with IEC 60898-1, IEC 61008, IEC 61009, IEC 62423 and IEC 60269-3;
\n– rated voltage to earth does not exceed 300 V a.c.;
\n– rated current (I<\/em>nc<\/sub>) of the outgoing circuits does not exceed 125 A and the rated current (I<\/em>nA<\/sub>) of the DBO does not exceed 250 A;
\n– intended for the distribution of electrical energy;
\n– enclosed, stationary;
\n– for indoor or outdoor use.
\nThis first edition cancels and replaces the first edition of IEC 60439-3 (1990), Amendment 1 (1993) and Amendment 2 (2001). It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60439-3 (including the amendments):
\n– alignment with IEC 61439-1:2011.<\/p>\n

This publication is to be read in conjunction with IEC 61439-1:2011. The contents of the corrigenda of September 2013 and March 2019 have been included in this copy.<\/p>\n","protected":false},"excerpt":{"rendered":"
