Neutral is a circuit conductor that normally carries current, and is connected to ground (earth) at the main electrical panel.
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. Ground 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. In the electrical trade, the conductor of a 2-wire circuit connected to the supply neutral point and earth ground is referred to as the neutral As the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely related. Under certain conditions, a conductor used to connect to a system neutral is also used for grounding (earthing) of equipment and structures. Ground 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. In the electrical trade, the conductor of a 2-wire circuit connected to the supply neutral point and earth ground is referred to as the neutral An electrical circuit containing one hot conductor and a neutral does not require a third ground conductor to function. Your ground can be a conductor or conduit for the purpose of creating aground fault current path. Ground-Fault Current Path. The Neutral for a circuit can be a Grounded conductor which is commonly called a (neutral) or as I explain to people an ungrounded conductor. 2. Some circuits get by without a neutral because a different energized conductor acts as a neutral. The neutral conductor is connected to earth ground at the point of supply, and equipment cases are connected to the neutral. The danger exists that a broken neutral connection will allow all the equipment cases to rise to a dangerous voltage if any leakage or insulation fault exists in any equipment. Ground 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. In the electrical trade, the conductor of a 2-wire circuit connected to the supply neutral point and earth ground is referred to as the neutral 1 The neutral wire is part of the GEC or Grounded Electrode Conductor which is part of the home electrical system. 2  The connection of the neutral wire and the ground system is made only at the main electrical panel which is where the bond is made to the earth ground. 1 The neutral is an insulated wire because it is part of the circuit which flows electrical current. 2  The Grounded Electrode Conductor. 3  Part (b). The Code requires the grounded neutral conductor of a 3-wire, 120/208V feeder-circuit to be the same size as the ungrounded phase conductors for a feeder-circuit derived from a 4-wire, 120/208V system. When sizing the load for a 3-wire circuit, the grounded neutral conductor must carry the unbalanced load of the two ungrounded phase conductors. This type of installation has an unbalanced load-unless both ungrounded conductors pull the same amount of current on each ungrounded phase conductor. The grounded neutral conductor of a 4-wire, 3-phase system supplying nonlinear loads must be the same size as the ungrounded phase conductors. The Code considers the grounded neutral conductor a current-carrying conductor due to the harmonic currents generated by these loads. When sizing the load for a 3-wire circuit, the grounded neutral conductor must carry the unbalanced load of the two ungrounded phase conductors. This type of installation has an unbalanced load-unless both ungrounded conductors pull the same amount of current on each ungrounded phase conductor. Ungrounded conductor = 14A. Grounded neutral conductor = 14A. Solution: Size the neutral conductor to carry a load of 14A. When sizing the load for a 3-wire circuit, the grounded neutral conductor must carry the unbalanced load of the two ungrounded phase conductors. This type of installation has an unbalanced load-unless both ungrounded conductors pull the same amount of current on each ungrounded phase conductor. Confidence votes 224. The neutral wire is a return wire for the current in an electrical circuit. Do not confuse for the ground wire which is also a return wire but is used in the event the connected appliance shorts to protect the user from electrical shock. The neutral is actually very similar to the ground, though.
