Dedicated Secondary SPD + PEN Fault Protection Unit (Supply & Installation Add-On)

Ensure complete regulatory safety for EV chargers without built-in earthing protection (such as the Tesla Wall Connector Gen 3). This all-in-one secondary enclosure provides combined PEN fault detection, surge protection, and circuit isolation in a single compact unit.

Key Features

  • Built-in Open PEN Fault Protection: Automatically monitors voltage and disconnects live, neutral, and earth in the event of a supply fault—eliminating the need for unsightly earth rods on PME (TN-C-S) supplies.
  • Integrated Type 2 Surge Protection (SPD): Shields your charger and vehicle against transient overvoltages and electrical grid spikes.
  • Dedicated Circuit Isolation: Fitted with a dedicated Type A RCBO / MCB to safely isolate the EV circuit from your main board.
  • Weatherproof Enclosure: Compact, IP65-rated enclosure suitable for indoor mounting near your meter or outdoor installation next to the charger.
  • BS 7671 & Regulation 722 Compliant: Fully meets UK 18th Edition wiring standards for outdoor EV charging safety.

Standard Supply & Installation Package

  • Professional Installation: Mounted adjacent to your main consumer unit or charger point, wired into your electrical supply by our qualified team.
  • 50-Mile Radius: Fitted as part of your EV charger installation within 50 miles of Peterborough.
  • Full Certification: Commissioned and documented on your installation’s Electrical Installation Certificate (EIC).

When Is This Required?

Select this add-on option during checkout if:
  1. You are purchasing a charger that does not have built-in PEN fault protection (e.g., Tesla Wall Connector Gen 3) installed on a standard PME supply.
  2. Your existing consumer unit lacks both SPD protection and spare ways to accommodate new protective devices.
  3. You want a single, clean solution that handles PEN safety, surge protection, and circuit isolation at once.
