With our houses running on more electricity than ever, a basic understanding of the cables and wiring in your home is vital. Use this fact sheet to learn about a variety of different kinds of wires before you start your next electrical project.. Wire and Cables Safety Tips
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.
It helps to understand a few basic terms used to describe wiring. An electrical wire is a type of conductor, a material that conducts electricity.In the case of household wiring, the conductor itself is usually copper or aluminum (or copper-sheathed aluminum), and is either a solid metal conductor or stranded wire.
Electrical Wires & Cables; More often than not, the terms wire and cable are used to describe the same thing, but they are actually quite different. Wire is a single electrical conductor, whereas a cable is a group of wires swathed in sheathing. ... An electrical cable also has different types, color and application as its determining factors. ...
Wire Types and Sizing . When wiring a house, there are many types wire to choose from, some copper, others aluminum, some rated for outdoors, others indoors. In general however, there are only a couple varieties used for wiring a residential home. Romex Cables . Romex (shown in yellow above) is the trade name for a type of electrical conductor ...
Types of Electrical Wiring: Wires & Cables. Non-Metallic Sheathed Wire. The electrical wiring system in most homes is created with non-metallic sheathed wire (NM). Commonly called Romex, this wire has 2-3 conductors as well as a bare ground wire and it’s coated in plastic.
Electrical wire comes in all sorts of different sizes, colors and types. How do you know what is the right one to use? We have many to choose from! Take a look at this handy guide for a quick summary. WIRE TYPES What are the different types of wire and what are they used for?
The various types of cable are also designated by how many conductors they contain and their size. For example, a cable identified as “14-2” with ground has one neutral and one hot wire as well as a grounding wire. The #14, designated by the American Wire Gauge, stands for the diameter of the wires alone, without insulation.
A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number.
Wire Types and Sizes Basic Electricity. ... Ask your students what effect different gauges of wire in the extension cord would have on this degradation of drill motor performance. Also, ask about different lengths of extension cord. What, exactly, is the electrical quantity that varies with these dimensional changes, that causes the drill motor ...
