Is line wire also called live wire?

Answer 1

Line is the left hole of an outlet. Neutral is the right, and ground is the upside-down semicircle. A live wire is a wire with current flowing through it. Because neutral doesn't have any current in it, but line does, you could say that line is live. This explains why that you can be shocked from touching just the line. You can't be by touching just the neutral or ground. Line to neutral is the most deadliest if it travels across you. Line to ground will tingle a lot, but it won't necessarily kill you because the current draw isn't nearly as much as line to neutral. But basically line is the most dangerous part of an outlet, so line or live, both are dangerous. :P Female Electricity Geeks will rule the world. Does this question matter? We will all die anyways XD but yeah. That's the gist of it.

Answer 2

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.

Answer 3

In electrical terms the common wire is the neutral or the wire that returns from the circuit load, so no the common wire is not the same as the line wire.
