⚡ Updated SBС В.2.5-23:2025 "Design of Electrical Installations of Residential and Public Buildings and Structures"

🗓️ Since January 1, 2026, the new edition of SBС В.2.5-23:2025 "Design of Electrical Installations of Residential and Public Buildings and Structures" has entered into force. It replaces SBС В.2.5-23:2010 "Design of Electrical Equipment of Civil Buildings."

🏗️ This document establishes modern requirements for the design of electrical installations in residential, public, and administrative buildings during new construction, reconstruction, and major repairs.

💡 Overall, the updated regulations are aimed at enhancing the safety of electrical installations, improving building energy efficiency, and adapting requirements to modern engineering systems.

Key innovations of the document include: 

🔹 Updated approaches to calculating electrical loads for residential and public buildings; 

🔹 Clarified requirements for internal electrical networks and their protection; 

🔹 Regulated application of guaranteed power supply systems (diesel generators, uninterruptible power supplies, etc.); 

🔹 Introduced requirements for electric vehicle charging infrastructure in buildings; 

🔹 Established the use of arc-fault detection devices (AFDD) to improve the fire safety of electrical networks; 

🔹 Updated requirements for electricity metering systems and automated building management systems; 

🔹 Clarified power supply requirements for high-rise buildings and healthcare facilities.

☝️ The new SBС harmonizes the requirements for the design of electrical installations with modern standards of electrical safety, energy efficiency, and the development of building engineering infrastructure.
