Understanding Amendment 3 to BS 7671: The Importance of Bi-Directional RCBOs

Amendment 3 to BS 7671, also known as the IET Wiring Regulations, introduces critical updates that enhance safety and compliance in electrical installations across the UK. One of the most significant changes is the requirement for bi-directional protective devices on all generating sets, including solar PV systems, battery storage, and electric vehicles capable of supplying power back to the grid (vehicle-to-grid). At Electrical4Less, we recognise the importance of this regulation and the vital role of Bi-Directional RCBOs in modern electrical systems.

Key Changes in Amendment 3 to BS 7671

The 3rd Amendment to BS 7671 emphasises improving safety standards and ensuring reliable protection against electrical hazards. The key change introduced is the mandatory use of bi-directional protective devices on generating sets such as:

  • Solar Photovoltaic (PV) Systems
  • Battery Storage Systems
  • Electric Vehicles with Vehicle-to-Grid (V2G) Capability

Why Bi-Directional RCBOs Are Essential

Bi-Directional RCBOs (Residual Current Breaker with Over-Current protection) are integral to modern electrical installations for several reasons:

  1. Enhanced Safety: These devices offer comprehensive protection against earth faults and over-current conditions, crucial for preventing electric shocks and fire hazards.
  2. Compliance with Amendment 3: Bi-Directional RCBOs ensure compliance with the latest BS 7671 standards, specifically the requirement for bi-directional protection on generating sets. This compliance is essential for meeting legal requirements and maintaining the highest safety standards.
  3. Versatility in Applications: Bi-Directional RCBOs are suitable for various settings, including residential, commercial, and industrial environments. Their ability to detect and protect against faults in both directions makes them highly effective for systems capable of feeding power back to the grid.
