why does my neutral wire have voltage

In defining voltage, you need to understand the concept of an electric circuit. You can think of a circuit as a large loop. For there to be power, electricity must flow continuously through the loop. Any interruptions to this loop will stop the flow of electricity.

A neutral wire helps to complete this loop by bringing current (electricity) back to the power supply, completing the circuit, and keeping the power on. 

Given this, a neutral wire should not usually have voltage. So, what could be responsible for a neutral wire having voltage? Let’s figure out.

Why Does My Neutral Wire Have Voltage?

Most (110 volts) electric lines have three wires: a “hot, a neutral, and a ground wire. The hot wire is traditionally black, while the neutral is white. Usually, electricity goes through the black wire to the device to be powered, then through the neutral wire back to the source (white wire).

When an electrical current flows through a neutral conductor, a condition known as neutral-to-earth voltage (N-E) or “stray voltage”, results. 

When there’s an electricity leak from the hot wire to the neutral or ground wires before travelling through the item in question, it causes a stray voltage. These leaks produce only a minor quantity of electricity.

The system would undergo “shorting” if the white and black wires came into direct contact, blowing a fuse or circuit breaker. In addition, frayed insulation and other mechanical issues can all cause stray voltage. 

Furthermore, various unconnected grounds might result in ground currents that can shock livestock. Leaks and non-connected ground systems that aren’t can create electric charges in the earth.

Persons or livestock exposed to certain equipment like metal stanchions will be electrocuted when the electricity travels through their bodies when these ground-based currents are present.

To make sense of all these, let us examine the concept of a neutral wire. What, in essence, is a neutral wire?

What Is A Neutral Wire?

A neutral wire is a circuit conductor that returns the circuit to its source. A neutral wire connects to the ground (earth) at the main electrical panel, street drop, meter, and the step-down transformer.

As we have mentioned earlier, neutral wire serves to complete an electric circuit. In addition, it serves as a pathway for energy to return to the source. For example, two hot wires carry electricity from the power source (battery) to the load. 

Alternating current electrical systems use ground and circuit conductors. The neutral circuit usually connects to the ground, while the ground circuit connects to the earth. 

Ground and neutral are closely related because the neutral point of an electrical supply system frequently connects to the ground.

How Can You Fix A Neutral Wire Having Voltage?

If you want to remedy this situation, you must first determine the causes. However, before you begin, note the following:

  • A panel receives 240 volts of power; two 120-volt circuits split the 240-volt supply. So, hot wires provide electricity into the panel. 
  • Large appliances, such as stoves, operate on 240 volts, and the circuit completes by connecting the large device to the two wires.
  • Smaller appliances operate on 120 volts, necessitating the use of a neutral wire. An open neutral is a break in the neutral wire that happens from time to time. 

Before you begin mending your open neutral, it’s vital to consider safety. You certainly do not want to be injured or worse. So follow the steps below to fix your open neutral.

Check the voltage:

A typical outlet should have 0 volts from neutral to ground. For hot to ground, use 120 volts. With your multimeter, check the voltage of your cables. If your neutral voltage is 120 volts, the neutral wire is unplugged.

Please switch off the power:

When working with anything electrical, it’s critical to cut off the power after verifying the voltage. This precaution is to keep you safe in the event of serious harm, such as electrocution. Make sure you have turned off the breaker at the source.

Remove the cover from the outlet:

Unscrew the screws that hold the outlet cover in place using your screwdriver. The number of required screws depends on the outlet. Remove the outlet cover after removing the screws.

Ensure there’s no voltage:

Use a voltage tester to ensure the circuit is dead after opening the outlet. The tester should read zero if the electric circuit has no power.

Remove the receptacle by unscrewing it:

Unscrew the receptacle after opening the outlet cover and checking the voltage. Then, remove any screws holding the receptacle in place using your screwdriver.

Keep an eye out for an open neutral:

Pull the receptacle gently apart to reveal the wires. Keep an eye out for the neutral wire. Also, check the neutral or white wire for any disconnecting once you’ve found it.

If necessary, replace the receptacle:

You’ll want to keep track of where the black and white wires attach to the current receptacle. You should carefully remove wires from the current receptacle. It’s crucial to consider your safety before you begin repairing your open neutral. 

Safety Precautions To Take When Fixing Your Neutral Wire Having Voltage

Even though electricity is a necessity in our modern lives, we must exercise prudence. Electrical safety refers to the measures we take to protect ourselves against electricity. Electricity-related injuries are often lethal. Electrical shocks, burns, and electrocution can all be caused by electricity. 

Even if you do not work in a dangerous environment where you are regularly exposed to electricity, you should practice electrical safety. 

Electric cords, overloaded circuits, water near electrical goods, unused plugged-in gadgets, and a lengthy list of other things can all constitute an electrical hazard at home.

Note that the kind of equipment in the vicinity will determine electrical safety rules. Therefore, you should always use protective gear when dealing with electricity and be aware of the risks. 

While you may be tempted to take a chance in some situations, never do so! Nothing is more important than your safety. 

Electrical fires can usually be avoided by following a few simple electrical safety rules and routine maintenance. In addition, having a professional inspection performed regularly can guarantee that your home is safe from electrical hazards.

Ensure there aren’t any overloaded outlets:

Electrical outlets work to give a specific amount of electricity. It may include enough plug-ins to charge your phone, headphones, laptop, and other devices, but it may be power-deficient. 

Overloading an outlet or plugging in too many gadgets at once might be dangerous. In addition, overloaded outlets might result in a small explosion or fire. A power strip that saves energy can help you safely fulfill your needs.

Use the suitable Watts in your lights and appliances:

We could presume that any lightbulb can be utilized for any lighting for those who aren’t particularly handy. Using improper bulbs, on the other hand, can result in electrical issues. 

Some light fixtures will display the recommended wattage, while others may not. Use a 60-watt bulb or less if a light fixture does not have a recommended wattage. For example, you can use a 25-watt bulb in unlabeled ceiling fittings.

Keep water away from electrical outlets and equipment:

This issue may seem self-evident to some, but not to others. Water can conduct electricity, whether you realize it or not, and the two do not mix well! 

So keep cords, electrical equipment, and outlets away from water, whether it’s a small amount on the counter or a bathtub full of it. 

While electrical outlets should be carefully positioned, they may be near water sources in some dwellings. If that’s the case, you should take caution.

Repair or replace damaged electrical cords:

Electrical wires can show symptoms of deterioration as they age, posing a potential electrical safety hazard. 

There’s a chance you have a brand-new power cord that shows indications of wear. Any damaged power cord poses a major electrical safety issue, as it can cause fire and electrocution. 

Regularly inspect all power cords for symptoms of wear and tear, such as fraying or splitting. If a power cord shows indications of wear and tear, you should change them as soon as possible.

Disconnect any appliances or electronics, not in use:

This precaution is a simple safety tip often overlooked. However, if you start doing it regularly, it should become a habit in no time. Unplug appliances and electronics when they are not in use. 

Doing this will not only reduce electrical hazards but will also save you energy. Even if you aren’t utilizing the appliances or electronics, they are still drawing electricity. You may be able to configure power schedules for outlets in some circumstances.

Conclusion

A neutral wire is a circuit conductor that returns the circuit to its source. The function of a neutral wire is to complete an electrical circuit. Therefore, it should not usually have voltage. 

However, this anomaly, also called stray voltage, can sometimes happen. An electricity leak is usually responsible for this.

Electric lines usually have a black, a neutral, and a ground wire. Usually, electricity goes through the black wire to the device to be powered, then through the neutral wire back to the source.
