what does a neutral conductor do
The neutral conductor is connected to earth at the building point of supply, but no common path to ground exists for circuit current and the protective conductor. In the TN-C system, a common conductor provides both the neutral and protective grounding.round is more common in North American English, and earth is more common in British English.) Under normal conditions, a grounding conductor does not carry current. Neutral is a circuit conductor that normally carries current, and is connected to ground (earth) at the main electrical panel.
