That way you can let everybody know that you are working and shouldnt turn on them. With a multimeter in your hands, you can test batteries, identify a wire, and even find a bad switch. A neutral wire is a wire that carries no electricity. If this isnt done correctly, electronics may short-circuit and fail to function, or you may even receive a dangerous electrical shock. Here is a step-by-step guide to identifying a neutral and hot wire using a multimeter. You can easily trace the cause of inconsistencies in your systems by recognizing the open neutral points and fixing them. If the wire is live, you will get a reading on the multimeter.

We can also use it to find hot wire. Some inexperienced electricians may mix up the wiring so you cannot always rely on color codes to tell a neutral wire from the other two wires. 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. How To Measure and Identify Resistor Using Multimeter & Color Codes? However, identifying the neutral wire can be challenging at times. (1).
