Why would four core armoured cable be used in a single phase circuit?
Four core armoured cable would be used in a circuit carrying 240 Volts 60 Hz AC that is installed in a location where it could get damaged, such as underground or under water. The 4 cores in the armoured cable would be used as the following conductors for the 240 V 60 Hz circuit: * "Red" hot (120V above Neutral)* "Black" Hot (120V below Neutral)* "Neutral"* "Ground" to protect the circuit, connected to the main incoming supply panel which feeds the circuit.
Why you use neutral pin in three pin plug?
In North America the neutral pin is used to complete the circuit. One pin is "hot", one pin is neutral and the last pin is ground.
What is the function of the neutral wire in a plug?
The green (or green with yellow strips) is for Earth. This is the D shaped socket in a US outlet. The Black (US) or Brown (UK) is for Live. This is the narrow rectangular socket on a US outlet. The White (US) or Blue (UK) is for Neutral. This is the wide rectangular outlet on a US socket. The color code may vary for other countries, so be sure to check.
Why neutral wire does not carry current in closed ac circuit?
The neutral wire does carry current in a closed AC circuit. Clamp a clamp on amp meter around the neutral wire directly after the circuit load and it will read the same current as is on the "hot" wire.
What is the need for neutral wires in circuits for electrical services?
The neutral provides a path back to the source for the electricity. In a three-phase circuit, it is mainly used to carry the unbalanced load back to the source. In theory, a perfectly-balanced three-phase circuit would not need a neutral, but this is almost impossible to achieve in actual practice.
What is the Difference between radial connection and ring connection of socket outlet?
In a radial circuit you wire 3 cables (live/hot, neutral and earth) from the board to the first socket, and then loop these cables on from socket to socket till you get to the last socket and you are finished.In a ring circuit, the is an additional set of cables from the last socket back to the board. This increases the load that can be put on the circuit.In my country (Ireland) this is generally not in practice any more, and most circuits are radial circuits.
Why does not tester light up when it is touched to neutral of 3 pin socket?
Because the neutral is simply the return path in a complete circuit. It doesn't carry any power - that's only found in the live wire.
Where is the position of black wire in electric socket?
In a household circuit, with a "hot" conductor insulated black and a white neutral, the black wire should connect to the center terminal of the socket. The outside part of the socket usually has a brass screw (for the black wire) and a nickel screw (for the white wire).
What is the latest technology in circuit breaker?
The latest technology used in circuit breakers are Arc Fault Circuit Interrupters. They will shut off the circuit if the hot and neutral or two hots touch.
Circuit diagram of an electric stove plugged into the socket?
circuit diagram is the most important in electric stove plugged into the socket
Why should you not connect any electrical switch to the neutral instead of the phase?
IF Neutral is connected to the Switch then Live still exists on the socket even if the Switch is OFF.In such a situation a person can get a shock as Live can form a circuit thru the body to Ground.
How can a integrated circuit be misused?
-- installed backwards in its socket -- used to build a death ray -- fed to a pet
What is a function of neutral wire?
to complete the circuit and back to power supply

How many neutral wires are needed for lighting and outlets?
If they are on the same circuit you only need 1 neutral wire in the circuit.
What is use of neutral link?
In a MEN (Multiple Earth Neutral) system, the neutral wire is connected to the earth wire at the switchboard. This is the neutral link. From an electrical point of view the neutral pin and the earth pin in a power socket are at the same potential but from a safety point of view they are different. A residual current device (RCD) (or earth leakage core-balance-relay(ELCBR)) sits in series with both the active and the neutral feed and a leakage from either wire to ground (via a human or water leak in a washing machine etc) will trip the circuit breaker that is in the RCD.Another AnswerFuses or circuit breakers must be inserted into the line conductor, never into the neutral conductor. However, if we need to isolate the circuit, we must place a break in both the line and the neutral conductors. We can achieve this for the line conductor by, for example, removing the fuse. To achieve the same with the neutral conductor, we can open the neutral link, which is simply a short length of conductor inserted between a pair of terminals in the neutral.
