 Knowing the basic [url=https://www.jxwirecable.com/]electric 

wire[/url] types is essential to almost any electrical project around 

the house. When you're installing new wiring, for example, 

choosing the right wire or [url=http://www.jxwirecable.com/electric-

cable/power-cable/]power cable[/url] is half the battle. And when you

’re examining existing wiring in your home, identifying the wire 

type can tell you a lot about the circuit the wiring belongs to—for 

example, when you open a junction box and need to determine which 

wires go where. Wiring for modern homes is quite standard, and most 

homes built after the mid-1960s have similar types of wiring. Any new 

electrical installation requires new wiring that conforms to local 

building codes.

Here are some common types of home electrical wire.

Wiring Terminology

It helps to understand a few basic terms used to describe wiring. An 

[url=http://www.jxwirecable.com/electric-wire/]electrical wire[/url] 

is a type of -conductor, which is 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. Most wires in a home 

are insulated, meaning they are wrapped in a nonconductive plastic 

coating. One notable exception is ground wires, which are typically 

solid copper and are either insulated with green sheathing or 

uninsulated (bare).

The most common type of wiring in modern homes is in the form of 

nonmetallic (NM) cable, which consists of two or more individual 

wires wrapped inside a protective plastic sheathing. NM cable usually 

contains one or more “hot” (current-carrying) wires, a neutral 

wire, and a ground wire.
