What to Do If You Have a Home Without Neutral

The neutral line is an essential wire that completes the circuit from the power source to all points of use in a home.without neutral line Without the neutral, there would be no path for electricity to follow, and a variety of dangerous issues could arise. But what happens if your house was built or underwent renovations before the neutral wire was included in electrical standards? It’s more common than you might think, and some of the smartest switches are designed for homes that don’t have a neutral wire.

The first thing to do if you suspect you have lost your neutral is to check the voltage of a few receptacles with a multimeter.without neutral line The voltage should be between about 110 and 125 volts. If the voltage is much higher or lower, you likely have a neutral line problem and need to call an electrician.

Another option is to check the voltage between the power source and your breaker box.without neutral line Typically, this will be about 120 volts. If the voltage is higher or lower, you likely have a faulty breaker that needs to be replaced.

A third option is to call an electrician, but this may be expensive and time-consuming.without neutral line If you do decide to call an electrician, be sure to explain the problem thoroughly and give as many details as possible.

Some people have the misconception that computers require a clean neutral connection to work properly, but this isn’t true.without neutral line In fact, many computer systems derive their power from two hot wires. As other devices are turned on and off in your home, the voltage in your computers will fluctuate. But as long as there are 120 volts on the hot wires, the computers will continue to function.

If you have a three phase system and connect it using a star or delta connection, then the neutral wire is optional.without neutral line However, it is usually connected in order to prevent imbalances in the load. This is because the star or delta connections can cause the current to travel to different sides of the load. When the neutral is connected, it carries the currents back to the supply star point to maintain the balance in the load.

Some manufacturers have tried to address the issue of homes without neutral by creating new switches that work well with a single hot wire. For example, Cync (formerly C by GE) developed a switch last year that doesn’t need a neutral wire. Another popular choice is the Lutron Caseta wireless in-wall dimmer, which can be used with Alexa or Google Assistant and works with most homes. It’s worth noting, though, that these switches do not provide the benefits of a neutral wire such as voltage regulation and the ability to prevent circuit breaker tripping. For this reason, they are not recommended for smart home applications.
