![]() It is an automatic switch to detect excess current and short circuits to protect the electric circuit. Therefore, it’s crucial to ground the neutral wires.Ī circuit breaker is commonly used to prevent the problems mentioned above of neutral wiring producing an electric shock. Perhaps, It can accumulate to the point causing overheating and fires due to a high voltage in the neutral wire. If you have not grounded the neutral, the electric current increases and heats the wire. Grounding neutral wires is a common practice to safeguard the entire electric circuit. However, if there is no reading, it’s a neutral wire. Just touch the multimeter to the exposed wires. To identify the neutral wire, you can use a multimeter. ![]() In fact, a neutral wire can be yellow, grey, or blue. Generally, the neutral wire is either white or grey, however, in some codes, it’s blue. It happens due to color code misinterpretation. Maybe your neutral wire is wrongly connected in place of a hot wire. Thus making the neutral wires out of capacity and balance, and you experience a hot neutral wire. These electrics have switch-mode power supplies that draw current in variable bursts. However, the current is imbalanced in most modern electrical appliances. This mechanism only works if the current drawn between the three phases is balanced. The returning current will balance out rather than returning to the power source through the neutral wire. In this system, the three phases are out of phase with each other. Sharing Of A Neutral Connection In A 3-Phase SystemĪnother reason for the neutral to turn hot is the practice of sharing the neutral connection in a 3-phase system. ![]() When you provide lower resistance to a neutral wire through your body, you’ll experience a hot neutral. If the wire is long, the resistance increases drastically to affect the performance of the electric system. But the resistance increases due to the increase in the length of copper wire. Copper is a good conductor of electricity with low resistance. Most wires in the electric circuit are made up of copper. When fixing the open neutrals, finding the break can be a bit difficult. This is because now your body will be the route with lower resistance than the neutral wire. If you touch an open neutral, you can expect an electric shock. Also, the low resistance of the neutral wire will be lost. This break disrupts the flow of current in its original route. This means that there is a break between the wire that connects the panel with the power source. Neutral wires become hot because they carry the same voltage as the live wire. Reasons For A Neutral Wire To Be Hot Open Neutral Wire Among multiple routes, the electric current will choose the path with the lowest resistance to complete the electric circuit quickly.The electric current changes its route with the help of alternate electric conductors in case of an abnormality. Electricity always tries to return to its power source.Hence, the current doesn’t reach back to its source. However, you don’t get an electric shock when wearing slippers because slippers cut off the electric circuit. If you come in contact with an electric circuit, your body will become a part of the electric circuit, and the current will flow through your body. Electric current flows in a complete circuit only.Also, you need to keep three essential things in mind: These color codes are crucial for a safe working environment and to stay compliant with National Electric Code. This color scheme is not absolute and can vary across countries. The neutral wires can be spotted due to their red color, neutral wires with white and ground wires with green color. Ground Wire – it’s a security wire used to give a substitute way to the returning current if there arises a framework glitch.Neutral Wire – nonpartisan wire that conveys the unused flow from an energy outlet back to the force source to finish the electric circuit.Hot Wire – also called stage or live, it’s a charged wire that conveys electric flow from the force source to the plug.Then only you can understand why a nonpartisan wire delivers an electric stun. But, the three distinct wires in a simple electric circuit convey electric flow between the source and the power plug.įirst, we need to analyze the capacity of each of the three wires. This is not due to the absence of current in the wire. It is because we don’t get an electric stun when we come in contact with such a wire while standing bare feet on moist ground. Neutral wires are generally misconstrued to not convey any electric flow in an electric circuit.
