The allocation of the low voltage electrical power general distribution board at buildings is
determined by technical, normative and economical parameters. A properly allocation of the
low voltage main board reduces the wiring lengths of the feeders and distribution circuits
designed for the installations, and, consequently, reduces the deployment costs as well the
operative costs (power consumption) related to power dissipation (Joule heating). This work
aims to develop and apply an optimization model for the optimal location determination of the
low voltage main board at houses, flats, commercial buildings and small industries. To solve
this problem, it has been adopted a network optimization model to determine the shortest route
to pass the conductors, in which results in costs reduction. For validation of the proposed
solution, it was performed a case study, where, taking real parameters, the definition of an
optimization technique executed in Excel Solver, has indicated a point considered as the optimal
location of the low voltage main board. Then, the obtained results were compared to location
returned by load center, method traditionally used. From this comparison, it was verified the
efficiency of the suggested method assuring a reliable and economical decision making.
