Usually the white wire is used as the neutral or negative. However, on three-phase, the wire may be gray.
On alternating current supplies the phase neutral is colored blue.
<><><>
For alternating current supplies no wire is referred to as the "negative".
"Negative" and "positive" wires are used in direct current electrical systems such as are used in cars and other vehicles. In those systems various different colors may be used to denote the negative side of the supply. The only sure way to know which wire is which is to use an electrical test meter.
But you have to know how to use a meter properly otherwise, if you set it wrongly, you can easily make it blow fuses - or even cause the meter itself to go up in smoke! So if you are ignorant about how to use a test meter correctly, you might find out that using one carelessly can prove to be a very expensive experience!
SAFETY ADVICE
Before you do any work yourself,
on household electricity supplies, equipment or appliances,
always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to ensure the circuit is, in fact, de-energized.
