How can I tell which wire is hot without color?
Place the prong of the multimeter’s black wire on the bare metal on the end of a white wire, then read the meter. If you get a reading, the black wire is hot, if you don’t, the black wire isn’t hot.
How do you tell if a wire is hot without a tester?
For example, get a light bulb and socket, and attach a couple of wires to it. Then touch one to neutral or ground and one to the wire-under-test. If the lamp lights, it is live. If the lamp doesn’t light, then test the lamp on a known live wire (like a wall socket) to make sure it actually lights.
Are wires hot when switch is off?
Meaning that if the switch is off but the breaker is on then one of the wires, typically a black or red wire could still be hot. If you are not sure which breaker to shut off, and you don’t have a voltage tester, then shut the main breaker off. Making sure that no computers are on before you do this.

How do I test if a wire is hot?
Turn the power off at the main panel. Remove the cover plate. Push the tester nose close to one, then the other, of the two switch wire terminals to see if either wire is still hot. If there are no live wires, unscrew the switch, pull it out and test all other wires in the box.
