EV Boards with Built-In Surge Protection (SPD)

These EV consumer units are supplied with integrated Type 2 surge protection devices (SPD), providing compliant protection for EV charger circuits under BS 7671 (18th Edition Amendment 2).

Using a dedicated EV board with built-in SPD ensures protection against transient overvoltage and avoids the need to retrofit separate surge modules at the main consumer unit.

Quick answer: EV chargers require surge protection to meet UK wiring regulations. Installing an EV consumer unit with integrated SPD ensures compliance and protects sensitive charger electronics from voltage spikes.

  • Type 2 SPD included – protection against grid switching and lightning-induced surges
  • Pre-wired RCBO/RCD protection – matched to EV load requirements
  • PME fault detection options – compliant installations without an earth rod
  • IP40 & IP65 enclosures – suitable for indoor and outdoor installs

All units are pre-configured for EV charger circuits and dispatched from UK stock with fast delivery options available.

Choosing an EV Board with Surge Protection

An EV board with an integrated SPD can provide a compact dedicated protection assembly. It must still be selected around the charger instructions, circuit rating, RCD or RCBO arrangement, supply and earthing system, PEN fault protection and enclosure location.

RCBO + SPD Boards

Combine individual overcurrent and residual-current protection with a Type 2 SPD. Confirm the charger’s external RCD and DC leakage requirements.

PME Protection Options

Some assemblies include open-PEN protection for relevant PME installations. Verify whether protection is built into the charger or required externally.

Indoor & IP-Rated Units

Match the enclosure to its location and preserve the stated IP rating through suitable mounting and cable entries.

Specification Checklist

  • Charger instructions: confirm circuit rating, RCD type and DC leakage arrangements
  • SPD configuration: match the supply, earthing system and installation assessment
  • PEN protection: establish whether the site requires an external open-PEN device
  • Enclosure: select for indoor, sheltered or exposed installation
  • Complete assembly: check included devices, spare ways, terminals and upstream coordination
