Key Features of Consumer Units with SPD Protection

  • SPD Selection: You should choose SPDs based on a detailed risk assessment. Ensure the SPD’s type and rating match the specific requirements and expected surge conditions of the installation.
  • SPD Location: Ideally, install SPDs at the electrical installation’s origin, usually at the main incoming supply point. This strategy maximises protection from external surges.
  • Integration Options: Some consumer units integrate SPDs directly, while others offer compartments for modular SPD installation. This flexibility helps in setting up and upgrading the system.
  • SPD Rating and Classification: You can categorise SPDs into Type 1, Type 2, and Type 3. Each type is designed to handle surges from different sources, tailored to the risks identified in your risk assessment.
  • Coordination with Other Devices: It is vital to coordinate SPDs with other protective devices like circuit breakers and residual current devices (RCDs). This approach ensures comprehensive protection.

Installation and Maintenance

  • Professional Installation: Qualified electricians knowledgeable in surge protection standards should handle the installation. This ensures safety and compliance with BS 7671.
  • Regular Testing and Maintenance: Regularly check and test SPDs to ensure they remain functional. They may also need replacement after a significant surge or as they reach the end of their service life.
  • Labeling and Documentation: Clearly label the consumer unit to indicate SPD protection and document details such as the manufacturer, type, and rating of the SPD. This documentation is crucial for maintenance and compliance checks.
  • Compliance with BS 7671: Ensure all installations adhere to BS 7671 and relevant European standards. Compliance not only enhances protection but also meets legal and safety requirements.

Conclusion

Installing SPDs in consumer units is a proactive approach to protect electrical infrastructure in various settings. Always consult with a qualified electrician or electrical engineer to customise the SPD setup according to the specific needs of your installation, ensuring both compliance and safety.
