What color is the positive in a 240v ac power cord?

Answer 1

There is no "positive" wire in an Alternating Current (AC) system, which is what a standard AC power cord or flex is used on. In a cord or flex for a small electrical appliance there is a always a "Hot" or "Live wire, a "Neutral" wire and maybe also a "Ground" or "Earth" wire. The "Hot" or "Live" wire is colored * Black in the US, Canada and other countries using a similar 60 Hz household AC power system.

* Brown in Europe and other countries using a similar 50 Hz household AC power system. The "Neutral" wire is colored * White in the US, Canada and other countries using a similar 60 Hz household AC power system.

* Blue in Europe and other countries using a similar 50 Hz household AC power system. The "Ground" or "Earth" wire is colored * Green in a cord or flex in the US, Canada and other countries using a similar 60 Hz household AC power system.

* Green and Yellow in Europe and other countries using a similar 50 Hz household AC power system. For more information please click on the Related Questions shown below.

Answer 2

"Positive" and "negative" are terms used in direct current (DC) electrical applications. The positive wire in DC applications is red (i.e. car battery).

"Hot" and "neutral" are terms used in alternating current (AC) electrical applications.

"Positive" is sometimes confused with "hot". If that is the case here, the hot wires can be any color, EXCEPT green, white, green w/ yellow stripes, or yellow w/ green stripes.

In homes, black and red are typically found. In some cases, the white wire in a 2- or 3-wire cable will be used as a hot to/from a switch.

Answer 3

You hav eto put your question in an understandable context for a precise answer. In home wiring there is typically a black, white and green or bare wire. The Black is hot, white is neutral and other is ground. Writing has nothing to do with it unless it is to differentiate different supply voltages. This may occur in a multi-voltage transformer in certain lighting fixtures.

Answer 4

Positive wire is red, at least on automobile batteries.

Answer 5

In AC there is no positive wire. A brown wire would be a hot wire.

Answer 6

A 240v cord like a dryer or range cord has TWO positives--one is red, the other black.

Answer 7

Usually red.
