no in resd. it's hot normally but if wired oppisate 2006 irc code
No. White wires are the "Neutral" ones while black wires are "Hot".
Black red and yellow is three-phase. there is no neutral.
The ribbed wire on a lamp cord is the neutral wire. On an extension cord there is no rib but the neutral wire is white in colour.
The black wire originating from a breaker box or fuse box is the live wire. However, in certain cases, the grey (or white) neutral wire can also be live. For example, the black wire may feed a lighting outlet, and if the neutral wire is broken on its way back to the neutral bar in the panel, then the neutral wire from the lighting outlet will be hot, because there is an electrical path from the black wire, through the light, and to the neutral. The point is, always check with a voltmeter before assuming the white or grey wire is not live.
In Bangladesh the color of live is green and neutral is blue and ground is black.
The white is neutral. The house does have a neutral wire even though it may be black. One of those black wires is the neutral and the other is the hot wire. You will have to determine which is hot and which is neutral. You can easily do this with a voltage tester. The wire that lights the tester is the hot. When you wire the light simply wire the hot to hot, and the white and green to the other wire.
Black red and yellow is three-phase. there is no neutral.
the thermostat has a black(line) wire to it, and a red wire going to it. the red wire then connects to the neutral wire. the black and red are like a leg switch.
The neutral wire and power wire are never connected together.

If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.
If you are asking about the electrical cord on a lamp, the black wire with the white stripe is the neutral conductor.
It just means that the bare wire is insulated by a non-conducting coating. In home wiring the typical circuit has a black wire (Hot), a white wire (Neutral) and a bare wire which is ground.
In residential wiring the white wire is neutral on the 120 volt circuits. On a 3way circuit the red is the traveler and the white is neutral. On a 240 volt 3 wire connection the white & black are hot. On a 240 volt 4 wire connection the black and red are hot and the white is neutral.
If this is a home wiring question and the wires are black and white then black is Hot and white is Neutral. If you also have a red wire, it is the other hot wire, and either the black or the red wire to the white one would be 120 volts, and red to black would be 240 volts.
