Stay Safe and Compliant: The Essential Guide to these Fault Detection Units for EV Charging
As the demand for electric vehicles (EVs) continues to grow in the UK, ensuring the safety of EV charging systems is more important than ever. A critical component in this safety is the PME (Protective Multiple Earthing) fault detection unit, particularly for EV chargers that do not have built-in PME or PEN (Protective Earth Neutral) loss protection.

In this post, we’ll explain why PME fault detection units are essential for safe EV charging in the UK market.
What Are PME Fault Detection Units?
PME fault detection units are devices designed to monitor the earthing system in an electrical installation. If a fault occurs—especially one involving the loss of the PEN conductor—these units automatically disconnect the power supply. This prevents potential hazards such as electric shocks or equipment damage.

These units are crucial in settings where EV chargers are installed, as they help maintain the stability of the earthing system, which is vital for safely charging vehicles.
The Importance of Fault Detection in EV Charging
Many EV chargers in the UK, particularly those in residential areas, lack built-in PME or PEN loss protection. This absence poses significant risks, as the loss of the PEN conductor can lead to dangerous conditions, including exposed live parts and improper earthing. PME fault detection units provide a crucial safety layer by automatically disconnecting the power in the event of a PEN conductor loss.
This protects not only the vehicle and charging equipment but also the user from potential harm. PME Fault Detection Units – EV Charging Safety
