2.1 The architecture design
The architecture design considered in this document is positioned at the Draft
Design stage. It generally covers the levels of MV/LV main distribution, LV power
distribution, and exceptionally the terminal distribution level. (see Fig. D2).

distribution
The design of an electrical distribution architecture can be described by a 3-stage
process, with iterative possibilities. This process is based on taking account of the
installation characteristics and criteria to be satisfied.
