This modification introduces updates primarily focused on enhancing clarity and safety in the application of Protective Multiple Earthing (PME) in low voltage networks. Key modifications include:

• Introduction of Open PEN Protection Devices (OPDDs) and reference to compliance with IET 01 standards.

The changes aim to improve public safety, clarify engineering practices, and futureproof the guidance in response to evolving technologies and deployment scenarios.
