both
On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot and neutral.
Electrical plug hot wireThe smaller blade of the plug is the hot wire, but both wires are in a way hot. This is because you are working with alternating current. Alternating current changes its direction of flow 120 times a second in the United States. An electrical cord can have different plug types. The most popular are the two and three prong type with the three prong type the smaller straight piece is hot, the larger straight piece is called neutral and the round one is ground. With the two prong you don't have a ground.
No, the ground wire should be attached to the green or bare copper wire. The black wires are typically live or hot wires and should never be connected to the ground wire.
Where there is a red wire involved that usually indicates some type of special switching arrangement or more likely a 240 Volt circuit. In this case there will be 240 volts across the red and black and they will both be hot. Normally for 120 Volts the black is hot, the white is common and the bare wire is ground.
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.
To determine which wire is hot when both wires are black, you can use a voltage tester or a multimeter to check for voltage. The wire that shows a voltage reading is the hot wire. Make sure to follow proper safety precautions when working with electrical wires.
In an electrical circuit, the black wire is typically the hot wire, while the white wire is the neutral wire. Both wires can carry electricity, but the black wire is the one that carries the current to the device, while the white wire completes the circuit by returning the current to the source.
The normal practice is for the black (or at least darker) wire to be hot. However, given the consequences of guessing wrong, they should be tested and both wires should be treated as "hot" until you find out differently.
On a 240 volt circuit both line wires are hot, so they may both be black, depending on the wire used. There is normally no neutral required unless you are also tapping off 120 volts between hot and neutral.
In an electrical circuit, the red wire is typically considered the hot wire, while the black wire is usually the neutral wire.
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 you are referring to lamp cord type wire where both wires are brown then yes, connect the wire with the groves to the white neutral and the smooth wire to the black hot wire.
Yes 1/0 wire can be used for both ungrounded( hot wires) and the grounded conductor (neutral).
Your black wires are your hot wires. The white is your neutral or common. It would be best to run an equipment ground (green wire) too.
Common wire colors found in old house wiring include black, white, and red. Black wires are typically used for hot wires, white wires for neutral wires, and red wires for secondary hot wires or switch legs.
No, the ground wire should be attached to the green or bare copper wire. The black wires are typically live or hot wires and should never be connected to the ground wire.
