What is an electrical wire, and how does it work?
An electrical wire is one of the conductors in your electrical system. It can be made of copper or aluminum and is typically covered in a PVC sheath. The sheath color indicates whether a wire is a neutral, ground or hot wire. But what are those things?
The first two terms are pretty self-explanatory: A neutral wire carries electricity from your breaker box to the device you're plugging in to, while a hot wire carries electricity back from that device to the breaker box where it gets distributed throughout your home. A ground wire delivers electricity to your breaker box so that it can be distributed throughout your home and also acts as a safety mechanism by providing a path for any excess electricity to get discharged safely outside of your home.
How to Identify Wires and Cables？
If you're looking for the best way to identify wires and cables, 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.
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, resistant to damage by oil or gas
X: Synthetic polymer, flame resistant
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, blue and yellow for hot wires pulled through 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 each color, so you can check your wiring system confidently.
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 maybe. 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.
When it comes to wiring your home or office, it's important to choose the right size wire for the job.
The proper wire size is critical to any electrical wire installation. 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 circuit and fire.
