What is electrical wires? Electrial Wires are a single electrical conductor, while cables are multiple conductors that have been encased in sheathing. Most wires are made of copper or aluminum, but they can also be made of steel. They may be bare or insulated, and they're typically covered in a thin layer of PVC. If they have a PVC sheath, then the PVC is colored to indicate whether the wire is a neutral, ground or hot wire in your electrical installation. We discuss wire colors in its own section in this guide. Cables contain at least a neutral wire, ground wire and hot wire that are twisted or bonded together. Depending on its purpose, the cable may contain more wires. The wires in a cable are insulated in their own color-coded layer of PVC. The group of wires is then encased 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 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 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: Hot wire for switches or outlets Red: Hot wire 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? 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 circuit 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.
