SPD Consumer Units for Domestic and Commercial Installations

An SPD consumer unit combines circuit distribution with surge protection in one enclosure. The surge protective device is designed to limit transient overvoltages and divert surge current, helping reduce the risk of damage to connected electrical and electronic equipment.

Main switch SPD consumer units are widely used in modern installations where individual RCBOs or other compatible protective devices provide protection for outgoing circuits.

Empty and Populated SPD Consumer Units

Choose between empty and populated consumer units depending on the installation. Empty boards provide flexibility when selecting individual protective devices, while populated boards are supplied with a predetermined combination of compatible RCBOs, MCBs or other components.

Always check exactly what is included with each board, as configurations vary between manufacturers and product ranges.

Choosing the Right SPD Consumer Unit

  • Number of ways – allow sufficient capacity for existing circuits and appropriate future expansion.
  • Empty or populated – choose an empty enclosure for a customised configuration or a populated board where a suitable device combination is already supplied.
  • Main switch rating – confirm the main switch is suitable for the installation and supply arrangement.
  • SPD type – many boards use Type 2 surge protection, while the required protection should be determined from the installation design.
  • Device compatibility – use RCBOs, MCBs, busbars and accessories approved by the consumer unit manufacturer.
  • Physical dimensions – check enclosure size, cable entry space and available installation area before replacing an existing board.

Main Switch Consumer Units with Surge Protection

A main switch SPD consumer unit provides a convenient arrangement for installations using individual protective devices on outgoing circuits. When RCBOs are used, a fault affecting one final circuit can normally be isolated without unnecessarily disconnecting unrelated circuits.

The correct surge protection arrangement depends on factors including the supply system, installation characteristics and required level of protection. Where additional or coordinated surge protection is required, SPD selection should form part of the overall electrical design.

SPD Consumer Unit Installation and Compatibility

Consumer units, surge protective devices and outgoing circuit protection should be correctly selected, installed and tested in accordance with BS 7671 and the relevant manufacturer’s instructions.
