What is an electric wire?
An electric wire is a single electrical conductor. It is typically made of aluminum or copper and can be insulated or bare. Electric wires are also known as "wires" or "conductors."
Electric wires are used to transfer electricity from one place to another. There are many different types of wires that you may encounter when working with electricity. These include telephone wire, power cable, lamp cord, coaxial cable, speaker wire, and computer network cable.
If you are planning on doing any electrical work on your home or business, then you should know how to identify an electric wire. This will help prevent accidents from occurring during installation or service calls by allowing you to quickly distinguish between different types of wiring in your home or office building.
In addition to knowing how each type of wire differs from one another, it's also important that you know what color each type of electric conductor should be used for certain applications such as lighting fixtures and appliances in order for them to operate safely without causing damage to anything else around them!
How to Identify Wires and Cables？
Wires and cables are one of the most important parts of your home's electrical system. They allow you to connect light fixtures, outlets, and appliances to your home power source (whether it's a generator or the grid).
But how do you know which wires are right for your project? It's easy! Each jacket will have information printed on it to help you choose the correct product for your job. A letter code provides the attributes of the wire, along with material, gauge, and voltage rating.
Naming and Taxonomy
The NEC provides a system with letters to quickly identify what a wire's capabilities are. Some common lettering for wire includes THHN, XHHW, THW, etc.
THHN is the most commonly used type of wire in conduit and cable trays for services, feeders, and branch circuits in commercial or industrial applications. Below are the letters and attributes you'll see regularly in residential wiring:
- T: Thermoplastic insulation - H: Heat resistance - HH: High heat resistance (up to 194 degrees Fahrenheit) - W: Suitable for wet locations - N: Nylon coating
Electrical Wire Color Coding
Hey there, DIY-ers!
We know you're all about that DIY life, and we want to help you make sure you know what you're doing (and how to do it safely!) when you start your next project.
When it comes to wiring, color coding is important. It's important not only because it helps identify the purpose of each wire, but also because it helps prevent accidents that could result in fire or electrocution.
Here's what you need to know:
Black = Hotwire for switches/outlets
Red = Hotwire for switch legs and connecting to hardwired smoke detectors
Blue & Yellow = Hot wires pulled through conduit; blue is often used for three- or four-way switch applications, and yellow is for switch legs to control fans, lights, etc.
White = Neutral (can be hot if marked with black or red to indicate it's no longer a neutral)
Green & Bare Copper = Only for grounding purposes
what is the red wire in electrical？
Red wires are hot, and it’s important to keep them clear of any other colored wires. If you have a red wire in your electrical system, it’s probably a secondary hot wire that is being used for other purposes.
For example, if you have a light fixture that is controlled by two switches (one to turn the light on and off and another to dim the light), then you’ll need two separate circuits for those switches which means two separate red wires.
You might also see a red wire if you have ceiling fans that are wired with three-way switches. A common mistake is to connect two fan circuits together by connecting one red wire from each circuit together. This will cause power problems because there will be too much current flowing through both fan circuits when they are turned on at the same time.
If you're installing a new electrical circuit or upgrading an existing one, it's important to choose the right wire size. The proper wire size is critical to any electrical wire installation. Wire sizing indicates the diameter of the metal conductor of the wire and is based on the American Wire Gauge (AWG) system. The gauge of a wire relates to the wire's current-carrying capacity, or how much amperage the wire can safely handle. When choosing the right wire, you must consider the gauge of the wire, the wire capacity, and what the wire will be used for.
Wires that are not properly matched to the amperage of the circuits they serve can create a notable risk of short circuits and fire.
