How Can One Tell Which Speaker Wire Is Negative or Positive? For the outlet to work as you expect, you must connect the right wires to the right terminals. If the outlet is two-wire, the wiring will be simpler and less time consuming. The multi-national research led by The University of Essex . In the case of a three-wire plug, the three colors represent the respective roles for each of the three wires in the connection. I completed my electrical engineering in 2014 and have been working since then. The neutral and hot wires are connected to the two vertical prongs at the top of the receptacle (neutral on the left and hot on the right), while the ground wire is connected to the round prong at the bottom. This is usually the left side of the plug when looking straight at it. How do you wire a 3 prong plug? For single-phase, single-voltage plug-and-socket-connected equipment, double fusing ALWAYS provides protection for both kinds of faults regardless of whether polarity reversal is possible or not. You will get a reading of about 9.2V. This is because the narrow prong always carries the live voltage, whereas the wide prong carries the neutral voltage. Like most modern testers, outlet testers are easy to use. Connect the white cord wire to the neutral terminal at the center. It is more important to maintain consistency.
3 prong plug wiring colors - Conquerall Electrical the neutral, which is the fat side. In this way, is the big prong on a plug positive?

While this answer is, in general true. Some three-prong plugs are also polarized, and when they are, the same rule applies: the larger prong connects to neutral. In some 3-way wiring setups, the ground wire may act as the common wire. Again, use pliers to tightly secure them in place. This device will show if a voltage is present in the wire and help to identify which black wire is the hot wire in question. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. The neutral wire will be white in most modern fixtures, while the hot wire will be red or black. But this doesn't mean that color-coding is always a reliable guide. For example, sometimes white wires are used in place of black wires, and some devices, like outlets and lamps, can be wired backward and still work (even though this creates a potential shock hazard). Red = pos, Black = neg green and white are the data wires. But you wont know that the heating elements have a current running through them until they shock you. It returns to the panel through the neutral wire.
