Use a paper or masking tape to label the hot wire so you easily identify it in the future. Other wires (the neutral and ground wires) show you a zero current reading. Remember that the hot wire is the one that the red probe is on when you get this reading.

If the multimeter presents a reading of 120V (with wires for lighting) or 240V (with outlets for large appliances), then that wire is hot or live. Once you position your probes, you check the multimeter for a reading. Place the red (positive) probe on one wire and the black (negative) probe on ground. Ordinarily, only the live or hot wire holds current when exposed, and this makes the whole test even easier.

There are typically three wires in the outlet and these are the live, neutral, and ground wires. Just remove any screws holding the pieces together and bring the wires out. To test which of the wires in a wall outlet is hot, you need to open up the outlet. The 250 VAC range is optimal, as the highest voltage reading you expect to get from home appliances and power outlets is 240V. Your home appliances make use of alternating current (AC voltage) and you set your multimeter to the highest range to get the most accurate reading.

Set The Multimeter To The 250 VAC Range.

You also wear protective goggles in case of sparks, keep your hands on the plastic or rubber part of the multimeter probes, and prevent wires from touching each other.Īs a first-timer, you practice with dead wires to avoid mistakes. Getting electrocuted is one thing you don’t want, so you wear protective rubber or insulated gloves before getting into it. When testing if a wire is hot, you definitely expect current to be running through it. The process is quite straightforward, but there is more to it. If the wire is hot, the multimeter shows a reading of either 120 or 240 volts, depending on the power output. Set the multimeter to the 250VAC range, place the red probe on one of the wires and place the black probe on ground. How To Test If A Wire Is Hot With A Multimeter
