Across
  1. 1. Abbreviation for a protective device that automatically "trips" in case of overcurrents or short circuits, preventing damage to wiring and equipment.
  2. 2. The purpose of this is to connect all metallic parts of an electrical installation together, creating an equipotential zone to minimize the risk of electric shock.
  3. 3. The action an MCB performs when it detects an excessive current flow, switching off the circuit
  4. 5. The fundamental purpose of this electrical safety measure is to provide a low-resistance path for fault currents to safely flow to the earth, preventing dangerous voltages.
Down
  1. 1. The presence of this significantly reduces the body's resistance and increases electrical conductivity, thereby elevating the danger of electrical shock
  2. 4. A dangerous outcome minimized by the process of bonding or heightened by the presence of moisture in electrical environments
  3. 6. Abbreviation for a protective device that is particularly important in locations containing a bath or shower, as it detects earth faults and provides additional protection.
