- 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).
