SPD Consumer Units with Main Switch

An SPD consumer unit combines surge protection with a main switch in one practical board. It helps protect the electrical installation and connected equipment from short-duration voltage surges caused by lightning activity or switching on the electricity network.

This range includes empty and populated boards for domestic and commercial installations. Empty boards allow the electrician to select the required protective devices, while populated options are supplied with a chosen combination of compatible RCBOs or MCBs.

Choosing the Right SPD Board

When selecting a board, consider the number of circuits, the space required for protective devices and whether spare capacity may be needed for future additions.

  • Number of ways: Choose a board with enough space for the required circuits and any planned additions.
  • Empty or populated: Select an empty board for a customised setup or a populated board for a convenient ready-selected package.
  • Device compatibility: Use only RCBOs, MCBs, busbars and accessories approved for the chosen consumer unit.
  • Board size: Check the external dimensions and available cable space, especially when replacing an existing fuse box.

Main Switch Boards with Surge Protection

Main switch SPD boards are commonly used with individual RCBO protection for each circuit. This can make it easier to identify faults and helps prevent a problem on one circuit from disconnecting the rest of the installation.

Most products in this category include a Type 2 surge protection device, although the correct SPD arrangement must be confirmed as part of the installation design.

Installation and Compatibility

Consumer units and protective devices should be selected, installed and tested by a suitably qualified electrician in accordance with the current edition of BS 7671 and the manufacturer’s instructions.
