If Do not penetrate walls or ceilings without first shutting off possible, install a new grounded receptacle. Selecting the appropriate size and type and handling it correctly is absolutely necessary to a successful electrical project that will pass inspection. Copper wire is the primary conductor of electricity in any home. The electricity itself travels on the outer surfaces of the wire, so wiring is normally added to the wires to protect against shock and fires.
The insulated wires are frequently grouped together and bound up in rugged plastic sheathing according to gauge and function. Multiple wires housed in shared sheathing form a cable. In some cases, the wires are grouped in metal or plastic tubes known as conduit.
Conduit also known as raceway is used primarily in situations where the cables or wires are exposed, such as open garage walls. This chapter introduces some of the many varieties of wire, cable, and conduit used in home construction and explains which types to use where. It also will demonstrate the essential skills used to run new cable, install conduit, strip diagram, make wire connections, and more.
Solid copper wires are the best conductors of electricity and are In most wiring systems installed afterthe wires and cables are insulated with pdf vinyl. This type of insulation is very durable and can last as long the most widely used. Aluminum and copper-covered as the house itself.
Beforewires and cables were insulated with A group of two or more wires enclosed in a metal, rubber. Rubber pdf has a life expectancy of about rubber, or plastic sheath is called a cable see photo, 25 years. Old insulation that pdf cracked or damaged opposite page.
The sheath protects the wires from can be reinforced temporarily by wrapping the wire damage. Conduit also protects wires, but it is not with plastic electrical tape. However, old wiring with considered a cable. An exception is a bare copper Wires must be large enough for the amperage grounding wire, which does not need an insulation rating of the circuit see chart, below right.
A wire cover. The insulation is color coded see chart, below that is too small can become dangerously hot. Wire left to identify the wire as a hot wire, a download wire, sizes are categorized according to the American Wire or a grounding wire. New cable sheathing is also Gauge AWG system.
To check the size of a wire, use color coded to indicate the size of the wires inside. Wire sizes shown actual size are categorized by the American In some circuit installations, the white wire serves as a wiring wire Wire Gauge system. The larger the wire size, the smaller the AWG that carries voltage.
If so, this white wire may be labeled with number. The ampacities in this table are for copper wires in NM black tape or paint to identify it as a hot wire. The ampacity for the same wire in conduit diagram usually more. The ampacity for aluminum wire is less. Pdf are covered with a layer of rubberized cloth, cloth fabric, but have butadditional no have no additional protection.
Metal clad cable MC and armored cable AC have been around since the s. Early versions had no grounding function, but existed solely to protect the wires that were threaded into it. Later armored cable products either had ground electrical twisted in with the flexible metal cover or relied on the metal cover itself for connecting to ground.
Modern MC contains an insulated ground wire along with the conductors. Metal conduit was installed during the middle of the 20th century as a way to protect hot and neutral conductors. The conduit itself often was employed for connecting to ground. Early NM nonmetallic cable was used from until It features a rubberized fabric sheathing that protects individual wires.
NM cable greatly simplified installations because separate wires no longer had to be pulled by hand through a conduit or armored cable. Early NM cable had no grounding wire. NM cable nonmetallic was developed cable was around developed around The UF underground feeder cable has wires embedded in a solid-core plastic vinyl sheathing and includes a bare copper grounding wire.
