DBOs have the following criteria:

  • intended to be operated by ordinary persons (e.g. switching operations and replacing fuse-links);
  • outgoing circuits contain protective devices, intended to be operated by ordinary persons;
  • rated voltage to earth does not exceed 300 V a.c.;
  • rated current (Inc) of the outgoing circuits does not exceed 125 A and the rated current (InA) of the DBO does not exceed 250 A;
  • enclosed, stationary and for indoor or outdoor use.

It is to be read in conjunction with AS/NZS 61439-1:2016. Adopted with national modifications from IEC 61439-3, Ed. 1.0 (2012).
