Low-voltage switchgear and controlgear assemblies - Part 3: Distribution boards intended to be operated by ordinary persons (DBO) (IEC 61439-3:2012/COR2:2019)

IEC 61439-3:2012 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 60898-1, IEC 61008, IEC 61009, IEC 62423 and IEC 60269-3;   - rated voltage to earth does not exceed 300 V a.c.;  - rated current (I_nc) of the outgoing circuits does not exceed 125 A and the rated current (I_nA) of the DBO does not exceed 250 A;  - intended for the distribution of electrical energy;  - enclosed, stationary;  - for indoor or outdoor use.   This 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):  - alignment with IEC 61439-1:2011.   This publication is to be read in conjunction with IEC 61439-1:2011.
