Connection pipe cross-section
Installations électriques BT

The conductors of an individual branch must be uniformly sized along its entire length.

Unless otherwise specified by the distribution system operator (DSO), the neutral conductor has the same cross-section as the phase conductors.

The calculation of conductor cross-sections must take into account the articles of standard NF C 14-100 for the calculation :

• the minimum cross-sections specified in article 5.3.3 of standard NF C 14-100 for individual power-limited connections (table 7 );

• the maximum permissible voltage drops indicated in 5.4 of standard NF C 14-100 ;

• of the operating current, taking into account the minimum power ratings indicated in 5.5 of standard NF...
