    The WMEPME08/SP is an 8-module PME / PEN Fault Detection Consumer Unit with integrated Type A RCBO and Type 2 Surge Protection Device (SPD) - designed for EV charger installations that require full PME fault safety without the need for an earth rod. This metal-enclosed unit continually monitors supply voltage and isolates Live, Neutral, and Earth within 5 seconds if it detects dangerous voltage conditions, keeping installers compliant with BS 7671:2018 (18th Edition, Amendment 2).

    Compact, installer-ready, and EV-compliant, it’s the ideal choice for chargers with integral DC leakage protection but no PME fault detection, such as many Tesla wall connectors.

    • Integrated PEN loss detection - automatic voltage monitoring with safe isolation
    • Type A Double Pole RCBO - 40A, C Curve, 30mA fault protection
    • Type 2 SPD - protects connected devices from transient voltage surges
    • No earth rod required - suitable for PME systems
    • IP40-rated metal enclosure - 8-module capacity
    • Available in multiple configurations (RCBO, RCBO+SPD, MCB+SPD)

    Do I still need an earth rod with this board?

    No - the integrated PME/PEN fault detection meets Amendment 2 requirements without a separate earth electrode.

    Is surge protection built-in?

    Yes - this model includes a Type 2 SPD to protect connected equipment from transient voltage surges.

    Can this be used for Tesla chargers?

    Yes - it’s ideal for Tesla and other EV chargers with integral DC leakage protection but no PME fault detection.

    This unit must be installed by a qualified electrician familiar with PME/PEN fault detection requirements. Ideal for EV charge points with built-in DC leakage protection but lacking PME fault safety.

    • Mount in a dry, ventilated location
    • Connect as per supplied wiring diagram
    • Verify PME isolation function before commissioning
    • Ensure SPD earth lead is kept as short as possible
