In accordance with BS 7671 (the IET Wiring Regulations) and modern electrical safety standards, consumer units (also known as distribution boards or fuse boxes) in the UK may include Surge Protection Devices (SPDs) to provide protection against voltage surges and transient overvoltages. SPDs are designed to safeguard the electrical installation and connected equipment from damage caused by power surges, such as those resulting from lightning strikes, switching operations, or other external factors.

Here are some key points regarding consumer units with SPD protection in compliance with BS 7671:

Selection of SPD: The choice of an SPD for inclusion in a consumer unit should be made based on the risk assessment of the electrical installation. The type and rating of the SPD should be suitable for the specific installation and the expected surge conditions.
SPD Location: The SPD should be installed at the origin of the installation, typically at the point where the electrical supply enters the building. This is often referred to as the main incoming supply point.
Integration: Some consumer units come with integrated SPDs, which means the surge protection device is built into the unit itself. Others may have a dedicated compartment or slot for installing an SPD module.
SPD Rating and Classification: SPDs are classified into different types (Type 1, Type 2, Type 3) based on their capability to handle surges from different sources. The choice of SPD type depends on the specific risks associated with the installation.
Coordination with Other Protection: The installation of SPDs should be coordinated with other protective devices, such as circuit breakers, fuses, and residual current devices (RCDs), to ensure comprehensive electrical protection.
Installation by Qualified Electricians: Installation of consumer units with integrated SPDs should be performed by qualified electricians who are knowledgeable about surge protection requirements and standards.
Testing and Maintenance: SPDs should be regularly inspected and tested to ensure they are functioning correctly. Periodic maintenance and replacement may be required, especially if the SPD has experienced surges or reached the end of its service life.
Labeling and Documentation: It’s important to label the consumer unit to indicate the presence of SPD protection and provide information about the device’s manufacturer, type, and rating. Proper documentation of the installation is essential for future reference and maintenance.
Compliance with BS 7671: The installation of consumer units with SPD protection must comply with BS 7671 and any other relevant British or European standards applicable to surge protection.

Consumer units with integrated SPD protection are a proactive measure to safeguard electrical installations and connected equipment against the potentially damaging effects of voltage surges. However, it’s essential to consult with a qualified electrician or electrical engineer when specifying, installing, and maintaining these units to ensure they are suitable for your specific installation and comply with all relevant regulations and standards.
