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.

Cut-Off Time and Order Information
To ensure your order qualifies for next day delivery, please place your order by 3:00 PM. This is subject to all items being available on the shelf at the time of your order. For orders where the total value exceeds £200 + VAT (double our standard carriage-paid order value of £100 + VAT), we are happy to split the delivery into two shipments if some items are needed urgently and others are not immediately available. If you have any questions or need further assistance, feel free to reach out to us via WhatsApp for live support. We’re here to help!

In Stock Delivery Policy

Free Next-Day Delivery Over £100 + VAT:
Orders above £100 + VAT qualify for free next-day delivery via DPD for in-stock items. While we strive for timely dispatch, we recommend placing orders early to avoid potential delays. Once dispatched, unexpected issues may arise despite the courier’s efforts.

Orders Below £200 + VAT:
To keep costs manageable, we dispatch your order once all items are ready, including products with longer lead times.

Need items faster? You can pay for an additional delivery service to receive in-stock items sooner. Simply email us with your order details, and we’ll send you a payment link for the extra delivery cost.

Orders Above £200 + VAT:
For larger orders, we can split delivery at no extra cost. In-stock items will be sent immediately, with the remaining items dispatched once available.

Supplier Lead Time & Availability

This item may be sourced from our supplier before dispatch.
The lead time shown is an estimate only and is based on the usual supplier timeframe. It is subject to supplier availability and is not a guaranteed delivery date.
We do not have a live supplier stock feed, so supplier stock can change without notice.
Delivery timers and courier estimates apply once the item is available for dispatch.
If the item is unavailable, we will contact you with the available options, including waiting for stock, choosing an alternative product, cancellation, or a refund for the unavailable item.
This does not affect your statutory rights.
