CME (circuit main earth)

CME (Circuit Main Earth) is the main earthing conductor or main earth connection in an electrical installation. It provides a low-resistance path from the electrical system to the ground (earth) helping to protect people and equipment from electric shock and electrical faults. Functions of a Circuit Main Earth (CME) Provides a safe path for fault currents to flow to earth. Protects people against electric shock. Helps circuit breakers and fuses disconnect faulty circuits quickly. Protects electrical equipment from damage caused by faults. Reduces the risk of electrical fires. Key Features Made from high-conductivity copper or copper-clad material. Connected to the main earthing terminal (MET) and earth electrode or earth grid. Sized according to electrical regulations and system requirements. Corrosion-resistant for long s ...
