What does it mean if one wire is hot and one is not?
You will get a reading if one wire is hot and the other isn’t. However, if both wires are hot, the reading will be zero. The United States has strict codes relating to home wiring, including clearly defined colors on the outer casing of the wires. Black means hot, white signifies neutral, and green indicates ground.
How can you tell if hot and neutral wires are reversed?
Measuring hot-to-neutral voltage by itself doesn’t tell you if those wires are reversed. You must measure neutral-to-ground or hot-to-ground voltage. If the neutral-to-ground is 120V and the hot-to-ground is a few volts or less, then the hot and neutral wires are reversed ( Fig. 1 ). Neutral-to-ground connection.
How can you tell if a black wire is hot?
If you get a reading, the black wire is hot; if you don’t, the black wire isn’t hot. Repeat the test on the other black wire to test if it’s hot. If you get a reading, the black wire is hot; if you don’t get a reading, the wire isn’t hot.
What’s the best way to test a hot wire?
Place the prong of the multimeter’s red wire on the bare metal on the end of one of the black wires. Don’t get confused about using the red wire from the multimeter to test a hot black wire.

Can a hot wire touch a neutral wire?
theory or real life? 1 Hot wire touches Hot wires: Short circuit –> Breaker will trip 2 Hot wire touches Neutral wires: Short circuit –> Breaker will trip 3 Hot wire touches Equipment ground wires (or metal enclosure): Ground Fault –> Breaker will trip
