Consumer units, also known as distribution boards or fuse boxes, play a crucial role in electrical installations by distributing electrical power to various circuits and providing protection against electrical faults and overcurrents. In accordance with the 18th Edition of BS 7671 (the IET Wiring Regulations), dual RCD (Residual Current Device) consumer units are commonly used in residential and some commercial installations for enhanced electrical safety. Here are some key points regarding dual RCD consumer units in compliance with BS 7671:

Residual Current Devices (RCDs): RCDs are electrical safety devices designed to detect and respond to earth leakage faults, which can occur when current flows to earth due to a fault or contact with a conductive surface. RCDs provide additional protection against electric shock and fire by disconnecting the power supply when such faults are detected.
Dual RCD Consumer Units: Dual RCD consumer units are equipped with two RCDs, typically referred to as RCD 1 and RCD 2. These RCDs provide protection for different circuits within the installation.
RCD 1: RCD 1 is usually a 30mA (milliampere) sensitivity RCD, which provides protection for socket outlets and other circuits where a higher level of sensitivity is required to prevent electric shock.
RCD 2: RCD 2 may have a sensitivity of 100mA or 300mA and is used to protect circuits that may have higher earth leakage currents due to equipment or specific installation conditions. This RCD is typically used for lighting circuits and other circuits where a higher sensitivity RCD might be prone to nuisance tripping.
Circuit Allocation: The allocation of circuits to RCD 1 and RCD 2 should be carefully planned based on the installation’s requirements and the type of loads connected. The goal is to achieve a balance between safety and practicality, ensuring that critical circuits are adequately protected.
Labeling and Documentation: Dual RCD consumer units should be labeled to clearly indicate which circuits are protected by each RCD. Documentation should also include circuit details and the location of the consumer unit for reference and maintenance.
Testing and Inspection: Regular testing and inspection of the consumer unit and RCDs are essential to ensure they are functioning correctly and providing the required level of protection. Testing typically involves the operation of the test buttons on the RCDs to verify their proper function.
Installation by Qualified Electricians: Dual RCD consumer units should be installed by qualified electricians who are knowledgeable about the 18th Edition of BS 7671 and local electrical regulations.
Coordination with Other Protection Devices: Consumer units with dual RCDs should be installed in coordination with other protective devices, such as circuit breakers and surge protection devices, to ensure comprehensive electrical protection.

Dual RCD consumer units are a common choice in residential installations because they provide an enhanced level of protection against electric shock and can minimize the risk of fires caused by electrical faults. However, the specific configuration and allocation of circuits to the RCDs should be carefully considered to meet the safety and operational needs of the installation. Always consult with a qualified electrician or electrical engineer for proper selection, installation, and maintenance of consumer units in accordance with the applicable electrical regulations and standards.
