Cei 64 8.pdf

Cei 64 8.pdf is the name of the file that contains the eighth edition of the Norma CEI 64-8, which is the Italian standard for electrical installations of buildings. The Norma CEI 64-8 specifies the requirements for the design and construction of low-voltage electrical installations and constitutes the reference standard for performing electrical installations according to the rules of art, as expressly required by the Law 186/68 and by the DM 37/08 on the safety of technical installations inside buildings.

The eighth edition of the Norma CEI 64-8 was published in 2021, nine years after the publication of the seventh edition. It integrates all the variants that have followed in the meantime, as well as several new contents. The main novelties of the new edition are:
