The common wire in a 120 vac system would be the neutral, the term line is used for incoming power to a device. Line can be made of two ungrounded conductors (hots) or one ungrounded conductor and one grounded conductor(neutral). Sometimes two or three ungrounded conductors (hots) and a neutral may make up the incoming "line" as in a three phase service. You will see the designation on some equipment at terminal strips for incoming line as L1 and L2. L2 usually being the neutral terminal.
On a 3-line wooden pylon, typically the top wire is the live wire, the middle wire is the neutral wire, and the bottom wire is the earth wire. It is important to contact a professional electrician to properly identify and work with these wires to ensure safety.
The white wire is typically neutral, the black wire is usually hot or live, the red wire may be a secondary live wire or used for a separate function, and the bare wire is typically the ground wire for safety purposes in an electrical circuit.
A fuse is typically connected to the live wire in a circuit. This is done to protect the circuit from an overload or short circuit, as the fuse will blow or trip and cut off the current flow if there is an issue.
On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot and neutral.
The Line normally refers to the live wire in a single-phase system and the three live wire of a 3-phase system. In a 3-phase system the line voltage is usually quoted as the nominal voltage, and that is the voltage between any two of the live wires. The voltage between one of the lines and neutral is 1/sqrt(3) times less.

You can use a wire tester to determine if a wire is live. You can also touch the positive wire on the ground wire, if the wire produces a spark it is live.
If a switch was on the neutral wire the live wire would still be at the mains potential even when the switch was off. This would cause on en electric shock when one handles any conductor linked to the live wire
The line wire will be hot and carrying power when the breaker is on. The load wire will not be hot and will have no voltage on it until it is connected with the line wire.

Line, phase, neutral are terms used to describe the conductors in a three-phase system. The three live wires are called 'lines', and less correctly, 'phases'. Neutral is used for the fourth wire which in a balanced system carries no current.
A metal rope is also called a wire rope.

A 'live' or 'hot' wire is a wire that is connected to a power source. This wire supplies voltage to a load ( light bulb, hair dryer, etc.). When the load is also connected a neutral or another live wire this becomes a path for the flow of current (amps) known as a circuit.
