In the US, if you only have a black wire (ungrounded or hot conductor) and a white wire (normally a grounded conductor or neutral) there is not a ground wire. Sometimes the white wire is used as a hot, so each wire would have to be identified.

Red is hot Green is ground 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.
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.
Load (or hot wire, usually black or red), Neutral, (white), and ground,(green) wire.
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
Red is hot Green is ground White is neutral
normally the blue and red wires are hot white is standaed for nutral,
You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
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.
If wired correctly the red wire will be hot, but any wire can be hot regardless of colour if done incorrectly.
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.
Red, white, and black are standard for a three-way switch (you have two switches that control the same fixture). You should also have a ground wire (copper, unsheathed). The black and red are negative, while the white is positive. It works pretty simply. When the switch is up, the black and white are linked, creating a circuit. When it is down, the red and white are linked. If both switches agree (both are red/white or both are black/white), then the circuit is completed and power flows.
The green or bare wire is typically the ground wire for a dryer plug. If your wires are black, white, and red, the white wire is usually neutral, the black is hot, and the red is also hot. You should double check with a voltage tester to be certain.
In a typical dryer plug, the two hot wires are usually the red and black wires. The white wire is typically the neutral wire and the green or bare wire is the ground wire. Always consult the manufacturer's instructions to be sure.
Yes, the red wire is typically considered a hot wire in electrical wiring.
The black wire is typically hot, while the white wire is neutral.
The red wire is the hot wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
