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？
When you're working with wires and cables, it's important to know how to identify them. 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.
For example, 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, resistant to damage by oil or gas
Electrical Wire Color Coding
Color coding is an industry standard for identifying a wire's purpose. It can be used to help the next electrician coming to a job site and advanced DIYers who plan to do some electrical work on their own.
Black: Hotwire for switches or outlets
Red: Hotwire for switch legs and connecting to hardwired smoke detectors
Blue and 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 and Bare Copper: Only for grounding purposes
what is the red wire in electrical？
Have you ever wondered what the red wire in your home's electrical system is for? You're not alone. Here's the scoop on what red wires are, and how to use them safely.
Red wires are usually used as secondary hot wires. These wires carry a current when a device is switched on, but they do not carry a current when the device is switched off. This means that you can always tell whether or not there's power running through a red wire by testing it with a tester—if there's power flowing through the wire, it'll light up.
Red wires are also hot and should be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch may be hidden above or behind them.
Choosing the right wire size is very important. It affects the safety of your electrical system, so you want to make sure you get it right.
In most cases, wire size is determined by two things: the current-carrying capacity of the wire (how much amperage it can handle) and what it will be used for.
When choosing a wire size, you'll need to know its AWG number, which is based on its diameter in thousandths of an inch (see table below). For example, if you're installing a new circuit for a home theater system, you'll want to choose a larger gauge wire that can handle higher amperages than if you were installing lights in your garage.
