Overview
ABSTRACT
This article is dedicated to the study of LV electrical installations and notably of connection rules in distribution networks. Connection is ensured by the end parts of the low-voltage public distribution network which bring the electrical energy of the network into buildings and households. The re-edited standards take into account the evolution of needs and technological evolutions. The protection of individuals, choice and implementation of materials and electrical conduits are also dealt with.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.

INTRODUCTION
Low-voltage connection installations are governed by standard NF C 14-100, regardless of the network operator. This standard was reissued in 2007 to take account of changing user needs and technological developments.
It also takes into account the construction of public distribution substations integrated into buildings, and in this case specifies the earth connection diagram.
Distribution system operators are referred to in this text as DSOs.
Standard NF C 14-100 specifies the conditions under which connection systems must be installed, the basic principles being those defined in the fundamental standard NF C 15-100.
