How do I know what type of wire insulation to use?

The first number represents the wire size or gauge, while the second represents the number of insulated wires. "14/2" cable, for example, is made up of two 14-gauge insulated wires. The 12/3 cable is made up of three 12-gauge insulated wires. Most NM cables feature a bare copper ground wire in addition to the insulated conductors. The term "grounded conductor" is used to describe this third wire.

Each conductor within the cable has its own protection from electrical damage. The insulation around each conductor prevents any voltage from being applied to it unless the cable is connected to another device with a voltage source. If even one conductor within the cable becomes damaged, however, then the entire length of cable becomes useless because it cannot be used without exposing all the other conductors to potential harm. Conductors are the pathway for electricity to flow within the cable so they must be kept free from damage for maximum efficiency when transmitting data.

Cable manufacturers specify the requirements for different types of wiring based on how easily they can be damaged by electricity. For example, power cables need to be able to carry high currents and withstand short circuits without burning up. Communications cables, on the other hand, need to be flexible enough to bend without breaking and should provide some form of shielding to prevent external electromagnetic interference from entering the cable.

There are four main types of wiring: neutral, hot, ring, and rome. Within these general categories, there are several specific types of wiring.

What type of wire is used in homes?

Non-metallic (NM) cable, which consists of two or more separate wires wrapped inside a protective plastic wrapping, is the most popular type of wiring in modern homes. A typical NM cable has one or more "hot" (current-carrying) wires, a neutral wire, and a ground wire. The hot and neutral wires may be colored red and white respectively. The ground wire is usually bare copper.

If you're installing new wiring in your home, non-metallic cable is the preferred method because it's safer for humans to handle and can carry more current than metal cable. If you choose to use metal cable instead, all the wires should be exposed outside their conduit or casing.

The term "wire" as used in this book refers to the conductor within the cable, not the entire length of the cable. A single strand of steel wire is called a "strand." Two or more strands twisted together are called a "core." A bundle of several cores is called a "run." Unless otherwise indicated, when I refer to "the" wire, I mean one of the conductors within the cable.

Cables have different names depending on their application. Home cables are referred to as "household electrical wiring" or "domestic wiring." Professional building cables are known as "structured wiring" or "metal-clad wiring."

What kind of wire is used for electrical wiring?

Conductors are often constructed of copper or aluminum, and the wire used is determined by needs such as current and voltage ratings. The entire area of the wire determines the current carrying capability. Wires must be able to carry the rated load for any one of several reasons: because they are overbuilt, meaning that they can handle more power than required; because they are designed to break before being overloaded; or because they are expected to see occasional loads above their normal maximum. For example, an extension cord provides extra safety margin because it is not expected to carry a full load all the time.

Cables consist of many strands of wire wrapped together to provide strength. These wires can be metal (usually iron or steel), glass, or plastic. Each type of cable has advantages for different applications. Metal cables are heavy and strong but also expensive and conduct heat poorly. Glass and plastic cables are less durable but cheaper alternatives if weight or cost is important. Any number of combinations of these types of cables can be used in a single application.

The final type of cable is called woven cable. This is similar to stringing multiple wires together but instead of wrapping them around each other, they are pulled through holes in a tube. This design is used primarily for its appearance and is found in fiber-optic cable.

What is a 14-3 wire used for?

14-3 cable (14 AWG-3 insulated conductors) enables two distinct hot conductors to share the same neutral. This is often necessary for three- and four-way switches, but I like to utilize it for the final leg of a circuit from the switch to the fixture. It's easy to forget about this last circuit when you're dealing with many lights, but it's important to remember because its conductors must be separated from those of other broken or live circuits.

The shared neutral allows both circuits to be turned off simultaneously by closing both switches, without fear of either burning down your house. The separate conductors ensure that if one conductor is energized, the other one is not (unless you have a short circuit somewhere in the system). Without a shared neutral, you would need at least three different conductors in order to achieve the same effect as using a shared neutral. For example, suppose Circuit A and Circuit B are supposed to control light FOO, but someone accidentally turns on Circuit C while they're at it. With a non-shared neutral, both FOO and FOC would burn out because they'd receive power from either/both Circuits A and B. But with a shared neutral, only FOO would burn out because it's not connected to Circuit C.

In addition to three-way and four-way switches, common types of fixtures that use 14-3 wiring include ceiling fans, heaters, and air conditioners.
