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 neutral, ground, or hot. 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?

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 wire or cable jacket.

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 are 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

So you're about to do some electrical work, and you've got a lot of questions. What's the best way to go about it? How can I tell what wires are hot? Is the color coding system different for every country?

The answer is yes. The color coding system is different for every country. And that's why we've written this article: so you'll know exactly how it works in your area!

The first thing to understand is that there are two types of color codes—one is universal, and one isn't. The universal color code was designed by the International Electrotechnical Commission (IEC). It's used around the world and helps electricians identify the purpose of each wire in an electrical circuit.

The second type of color code is often referred to as a local or country-specific code because it varies depending on where you are in the world. These codes were developed by individual countries' governing bodies or organizations with an interest in electrical wiring systems; they may or may not conform to international standards.

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

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 Wires

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

Wire Sizing

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.
