Currently, the General Regulations on Electrical Installations (RGIE) are primarily oriented towards alternating current electrical installations.
Given the increasing presence of direct current systems in low-voltage and extra-low-voltage electrical installations (storage batteries, photovoltaic panels, etc.), changes have been made to Book 1 of the RGIE and relate to:
- the addition of grounded direct current systems (TN, TT, and IT) that determine the characteristics of electrical installations:
- definition of these systems
- active protection measures against electric shock by indirect contact for these systems
- taking into account the impact of the addition of grounded direct current systems on the requirements of Book 1 (general definitions, other protection measures, selection and use of electrical equipment, etc.)
- the integration of the new terminology of the amendments and the editorial verification of the existing parts that have been examined in light of the amendments. This is also included in Book 2
The report to the King accompanying the Royal Decree of October 6, 2025 provides explanations on the content of these amendments.
