nollajohdon
Nollajohdon, or neutral conductor, is a conductor in an electrical installation that carries current back to the source and is typically at or near earth potential during normal operation. It forms the return path for current in circuits that include a live (phase) conductor and a load. The neutral is distinct from the protective earth conductor, which provides a safety path for fault currents.
In many power systems the neutral is bonded to earth at the main service entry or at
The neutral conductor should be insulated and protected like other conductors. Circuit protection is typically provided
Common issues include an open neutral leading to unstable voltages at outlets and malfunction of equipment,
