You probably have a neutral wire in every outlet in your home, but do you know When did neutral wires become standard? The truth is, the number of “neutral” wires you have may be dependent on the year your house was built. But more importantly, knowing what it does and why it’s there can help keep you and your family safe. If you’ve ever wondered, “when did neutral wires become standard?” or wanted to know more about this protected conductor in every outlet, read on!
Neutral wires first appeared in the late 19th century. In 1880, the International Electrical Congress met in Paris to standardize the use of electric systems. It was then decided that a grounded circuit, or neutral wire, would be a good idea. The first building wired with a neutral wire was the headquarters of the London Electric Supply Corporation in 1889.
The first home with wiring for a neutral wire was the home of the German physicist Heinrich Hertz. He had his laboratory wired with a neutral wire in 1890. In 1892, the Royal Institute of Technology in Stockholm, Sweden was wired with a neutral wire. In 1894, the Holborn Viaduct in London was wired with a neutral wire.
What is the neutral wire?
The neutral wire is the third wire that connects to the service equipment. When you are installing an outlet in your home, the service equipment and the neutral wire connect together. In most cases, the service equipment will be located in the garage, but it can be anywhere within the house.
When you have a three-wire circuit, the neutral wire is the third wire. This is because the neutral wire is connected to the neutral side of the service equipment. If you were to remove the neutral wire from the circuit, the voltage would drop on the neutral side of the service equipment.
Types of neutral wires
Wiring diagrams are the backbone of every electrical system. They are essential to understanding what is going on in your home. As a homeowner, it is important that you know how to read a wiring diagram and understand how to install it properly.
A wiring diagram can be tricky to understand because there are so many types of wires. Different types of neutral wires are usually labeled on the diagram. It is important to understand which wires are which so that you can figure out how to connect them correctly.
There are three main types of neutral wires:
- Ground wires
- Earth wires
- Wires that carry power to outlets
Understanding these three types of neutral wires will help you understand how to wire your home.
Ground Wires
Ground wires are always red. Ground wires carry no electricity. They are usually connected to metal objects in your home like a water pipe or an outlet box. Ground wires should never be connected to another grounding wire.
Grounding wires should be placed on the ground or on a metal object in your home. Grounding wires should never be connected to a wall or other metal object. If a grounding wire is connected to a metal object, it will prevent the flow of electricity.
Earth Wires
Earth wires are black. They carry no electricity. They are usually connected to the earth or the ground. They should be connected to a metal object in your home. Earth wires should never be connected to another grounding wire.
Earth wires are usually the same color as the ground.
Wires that Carry Power to Outlets
The outlet wires are white. They carry electricity. They are usually connected to metal objects in your home like an outlet box.
When did neutral wires become standard?
Neutral Wires became standard in the 1890s with the introduction of GFCI outlets. Before that, conductors were protected with ground wires. The ground is still used in most buildings but is considered less desirable than neutral, which is why it is often disconnected when an outlet is rewired.
Wiring a house with two separate hot and neutral 12-volt cables began in the early part of the 20th century. But it took time for this system to become the standard. In the mid-19th century, for example, homes were commonly wired with a single heavy, common circuit wire running from a central source, such as a gas main, for all the electrical appliances in the house. In large houses, a cable, rather than a wire, was often used. For a time, a single-wire system was the only type available.
When you are trying to set up a network, try to use UTP cables with solid color cables. You can use 4 pairs of solid colored cables that have different colors for the pairs. The colors of the wires are used to help you with the network setup. If you are not using a solid-colored cable for each pair, you can use solid-colored wires with white stripes. Now, if you are using solid-colored wires, you can install the pairs in any order you want. If you are using solid colors with white stripes, then make sure that you install the pairs in the order that they are on the cable.
The earliest installations of electric service were probably direct connections to the light bulbs, motors, and other appliances in homes, factories, and offices. But early in the 20th century, engineers realized that connecting all of the wires in a building or other structure to one another would not only create a short circuit but would increase the risk of dangerous fires. That’s because if one wire suffered damage, it would quickly become a conduit for large amounts of current, potentially causing a fire. The solution was to connect the building’s power source to its electrical circuits with neutral wires.
What does a neutral wire do?
You may have heard of a neutral wire, but do you really know what it is and what it does? The answer is yes! Neutral wires are a part of the wiring system in your home and provide power to appliances and electronics.
A neutral wire is simply a wire that does not carry any electrical current. It is important to know what a neutral wire does so that you can identify it in your home. Here are some things to keep in mind:
A neutral wire carries electricity from your power source to all of your home’s outlets and appliances. If you plug something into a power outlet that doesn’t have a neutral wire connected, the device won’t work properly.
A neutral wire is usually yellow in color. If you have an appliance that needs to be plugged into a power outlet that has a neutral wire connected, it will look for the neutral wire first, then the other two wires.
