What is electrical wires? When you hear the word "wire" or "cable," you probably think of electricity. And when it comes to electric wiring, these terms are used interchangeably. But there are some key differences between the two. A wire is one electrical conductor and cable is multiple conductors encased in sheathing. Electric wires are typically made of aluminum or copper. They're either bare or insulated and can be covered in a thin layer of PVC that's colored to indicate whether the wire is a neutral, ground, or hot wire in your electrical installation. We discuss wire colors later on in this guide. Cables contain at least one neutral wire, ground wire, and hot wire twisted or bonded together—the number of wires depends on its purpose. The wires are then insulated and encased in their own color-coded layer of PVC before being wrapped in an outer sheath to make up the single cable.


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 regularly see 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? 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.


Wire Sizing 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 its 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.
