how to identify neutral wire without multimeter
Heres a short video on how to use a multimeter for beginners: Determining the nature of a wire using a multimeter is a much safer option than using colors because, as stated before, there is no consistent color of hot, neutral, and ground wires. Now, if there is no beep sound in the meter or its green light doesnt turn ON, it shows that one of these wires (white in case of two-wire systems; blue and white in three-wire design) carries AC voltage. Insert the tester inside every outlet and check if additional outlets have an open neutral. Method - 3 Connect Wire to the Lamp to the Ground. More about us. So avoid performing further tests until you are sure that this circuit of your house powers no more additional appliances. 5. If the multimeter shows discontinuity between the neutral wire of two outlets, there is some issue with the neutral wire between the two tested points. You can make a secure connection in an outlet by identifying a neutral wire. Electricity tasks are not easy to do; you always have to be cautious when dealing with them.

Insert your tester into the positive side of the outlet. Using a digital multimeter, I measured the voltage between each pair of the six wires and the metal housing with the circuit turned on, as well as the resistance between the metal housing and each of the wires with the circuit turned off. A white/neutral wire can just be laying in the wire nut, and not actually be tight with the others. It is usually green or copper in color. Read more. And How you identify it? If it does not light up, then there is no electricity running through the screwdriver. 2.We take a tester and connect one end to the first wire and the other to ground. Never work with a live circuit while your hands are wet. The two wires are red and black; the red wire is the positive wire in most cases. Now set your multimeter to the highest voltage reading. If wikiHow has helped you, please consider a small contribution to support us in helping more readers like you. Step 4 - Use the Red Probe. All wiring looks the same on the inside, but the outside coverings come in different colors. Using the wire colors and testing with a multimeter helps you be certain about the wiring. If that is the case, use the screwdriver to remove the screws and the plastic cover. For example, if your houses electric power supply line were cut during a thunderstorm, the ends of that wire would present a voltage difference to the ground it is live. The neutral conductor provides a continuous path for electricity to flow. When dealing with electricity tasks, its very important to be cautious and not to touch any metal. These standards follow color codes, which also apply to the home wiring. Earth Wire: Comes in yellow or green colors.
