It can be difficult to tell which wire is hot on an electrical circuit without a multimeter. A wire that gives around zero voltage with ground wire is the neutral wire, as neutral doesnt supply current instead, it provides a path (loop) for the current back to the power source. Lives In: Denver Colorado On outlets in the middle of the circuit, the neutral wire makes it possible for the current to move through the outlet to other outlets on the circuit and back to your service panel. Different types of multimeters: Analog multimeters are ancient and less commonly used in todays world. The multimeter does not produce any reading if the wire is neutral. For example, you can find small writing on the wire. 1.Now that we have our tool, we need to find grounding. The wire that does not give a voltage reading is the neutral wire. There are a few simple steps you can take to use a non contact voltage detector to find out what wire is hot: 1. The majority of detectors in the industry work on a very simple principle: they induce an alternating magnetic field in the object, and if there is voltage present, this induced field will cause current to flow. To use a digital multimeter to test a neutral wire, we recommend the following steps: Set the multimeter to the highest voltage setting in the AC range.Next, hold the black test lead and connect it to the ground wire. You can do this by using a meter or other tool to test the wires. Therefore. And If you dont get a reading on one of them, that one is the neutral wire. An open neutral can disconnect the system or might cause inconsistency. 3. When the neutral wire in an outlet is not connected or loose from the breaker or the outlet, an open neutral may cause a drop or increase of voltage and end up burning your appliance, as the current return path is defective.
