What is the hot wire color in a phone line?

Answer 1

Answer for USA, Canada and countries running a 60 Hz supply service.

Normally a hot wire is black.

When more than two wires are used, a red wire can also be a hot wire.

The white wire is the neutral.

A green or bare wire is the protective ground wire for the safety of the users of appliances and other equipment that gets plugged into the home wiring socket outlets.

Answer for countries in Europe and other world areas running a 50 Hz supply service.

Normally a hot wire is colored brown. (On old wiring circuits a red wire can also be the hot wire in combination with black for neutral.)

For the hot wire going from a switch to whatever appliance is being switched (e.g. from a light switch to a lighting fitting) any other color except green or yellow/green may be used but whenever a brown wire is not used it must always be clearly marked as a potentially live wire by covering the wire's insulation at each of its ends with some standard pvc sleeving that is colored brown.

The color blue is used for the neutral wire. (On old wiring circuits a black wire can also be a neutral wire.)

A green/yellow striped wire (it should never be a bare copper wire) is the protective earth wire (also known as a ground wire) for the safety of the users of appliances and other equipment that gets plugged into the home wiring socket outlets. (On old wiring circuits a green wire can also be the earth wire.)

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

Answer 2

Answer for USA, Canada and countries running a 60 Hz supply service.

For a 120 volt circuit, the "hot" wire is normally black.

For a 240 volt circuit, the "hot" wires are normally black and red.

Answer for the U.K.

In older installations the 'hot' (live) is red and neutral is black.

On newer installations the 'hot' is black or brown and neutral is blue.

For most of Europe

Between the consumer (fuse or distribution) box and any switch or a socket, hot (live) is brown, neutral is blue.

Between a switch and the switched item (eg a light) the hot is black.

(Care - the differentiated use of black / brown is not strictly followed, even within a property)

Answer 3

It depends entirely upon the electrical standards of the country in which the conductor is used. The correct term for the 'hot' conductor, incidentally, is 'line' conductor. For example, in North America, a single-phase line conductor is coloured black; in Europe, the corresponding conductor is coloured brown.

Answer 4

generally black. But can be red or almost any other color except white, gray, or green

Answer 5

Red and Black wires are hot, White wires are neutral, and Green or bare wires are ground

Answer 6

There are usually 4 colored wires in a phone line. The red and green wires are the hot wires.

Answer 7

Black or red is hot, white is neutral, green or green with yellow strip is ground. This is according to the National Electrical Code.

Answer 8

black
