If there are a red wire a black wire and a bare wire in a 120 volt supply wire which is the hot 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.

Is red or white neutral for electrical work?

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.


Is the black wire the hot wire in PCs just like in home wiring and AC circuits?

No, internal PC wiring colors do not correspond to the standard AC wiring colors. Computer power supplies provide direct current to the computer and peripherals. When using direct current, the black wire is the ground wire. The red wire to the peripheral supply cables are 5 volt, and the yellow wire is 12 volt. Some SATA power connectors have an orange wire that is 3.3 volt.
