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？
There are a few different ways to identify your wires and cables. The most common way is to look for the letters printed on the jacket of the wire or cable.
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.
A common system used by the National Electrical Code is 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 is some common lettering for residential wiring:
T: Thermoplastic insulation
H: Heat resistance
HH: High heat resistance (up to 194 degrees Fahrenheit)
W: Suitable for wet locations
Electrical Wire Color Coding
Electrical wire color coding is a system that uses color to indicate the purpose of each wire. The colors help identify the wires, which is important in an industry that relies on standardization.
The purpose of the electrical wire color coding is to make it easier for electricians, as well as advanced DIYers, to identify which wires are hot and which are neutral. This helps prevent any potential accidents from occurring when working with electricity.
The most common colors used in electrical wire color coding include black for hot wires, red for hot wires that connect to switches or outlets, and blue and yellow for hot wires pulled through a conduit (blue is often used for three- or four-way switch applications and yellow is for switch legs that control fans and lights), white for 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？
You've probably encountered a tangle of colored wires when trying to understand your home's electrical system, and you're not alone. It can be confusing! But we're here to help you understand what each color means, so you can check your wiring system with confidence.
First things first: if you're having trouble with your home's wiring system or it's older than you are, we recommend you utilize a certified electrician. You don't want to make matters worse by getting in over your head!
Red wires are usually used as secondary hot wires. They're also hot, so they should always be clearly marked to avoid the dangers of electrocution. Red wires are commonly used when installing ceiling fans, where the light switch may be. If there's already a red wire in place, it may not be necessary to add another one—but do check with an electrician before proceeding just in case!
Green insulated wires are often used for grounding purposes. Ground screws on electrical devices are often painted green too—so never use a green wire for any other purpose than for grounding because this may pose a serious threat of electrocution for you or a professional
To ensure you have the right wire size for your electrical system, you need to consider the gauge of the wire, what it will be used for, and it's capacity.
Wires that are not properly matched to the amperage of the circuits they serve can create a notable risk of short circuits and fire.
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.
