The WMEPME10/SP PME Fault Detection Consumer Unit is a larger 10-module metal enclosure fitted with a 4 Pole 63A Type A RCBO and an integrated Type 2 Surge Protection Device (SPD). It provides full PME/PEN fault detection, automatically disconnecting Live, Neutral, and Earth within 5 seconds under dangerous voltage conditions. Fully compliant with BS 7671:2018 (18th Edition, Amendment 2), this board eliminates the need for an earth rod while also protecting downstream equipment against transient surges.
The extra module space compared to the 8-way variant makes it a strong choice for installs where additional wiring room is needed or future expansion is likely. Ideal for EV charger installations where PEN protection and surge resilience are both required.
Installer Tip: Choose the 10-module variant when you need extra wiring space for tails, isolators, or future expansion. It includes the same RCBO + SPD protection as the WMEPME08/SP but with more room for neat installs.
Key Features
- Integrated PEN fault detection – full isolation of Live, Neutral & Earth under fault
- 63A Type A RCBO – 4 Pole, C Curve, 30mA residual protection
- Type 2 SPD – shields against transient voltage surges
- 10-module steel enclosure – IP40 rated, pre-wired, installer-ready
- No earth rod required – compliant with PME installs under Amendment 2

Do I still need an earth rod with this board?
No – the integrated PEN fault detection complies with Amendment 2 and eliminates the need for a separate electrode.
What’s the difference between the 8-module and 10-module SPD models?
Both include a 63A RCBO and Type 2 SPD. The WMEPME10/SP provides more wiring space, making it better for neat installs or future expansion.
Is this suitable for EV charger installs?
Yes – it’s ideal for EV charge points requiring PME protection and surge resilience, with additional room for flexible wiring.
