What is NOT a component of a MEN system found in a low voltage installation?

In a low voltage installation, a MEN (Multiple Earthed Neutral) system is designed to ensure safety and stability in the electrical distribution network. The components of a MEN system typically include a main earth bar, an earth electrode, and a MEN link, which serve to connect the neutral point of the supply transformer to the earthing system.

The neutral transformer, however, is not a component of the MEN system itself. Instead, it is the transformer that supplies power to the system and has its own neutral point. The MEN concept focuses on ensuring that the neutral is properly grounded to minimize the risk of electric shock and enhance system safety.

In contrast, the main earth bar is essential for bonding different earth connections, the earth electrode provides a physical grounding point, and the MEN link creates the necessary connection between the neutral and earthing systems. Thus, the neutral transformer does not fit into the category of components that constitute the MEN system.
