What Is 14/2 Wire Used For

When most people think about wiring, they think about the basic electrical wiring in their home- copper wire for carrying electricity. But there’s a wide variety of other types of wire that can be used for different applications. One such type is the 14/2 wire. What is it used for? And is it right for your needs? Read on to learn more.

Understanding 14/2 Wires

In a 14/2 electrical wire, the number 14 indicates the gauge of the conductor, while the number 2 means the number of conductors within the cable.

A 14/2 wire is a jacketed electrical cable with three 14-gauge electrical conductors:

  • Black and White “Hot” Wires – they transfer current from the panel to the item, which could be a switch, light fixture, receptacle,  or appliance. Other colors for hot wires exist, although they’re far less prevalent.
  • Ground Wire, Green or Bare Copper – in a ground fault, ground wires provides a channel for the fault current to return to the panel, opening the breaker or blowing a fuse and cutting off the electrical supply.

The National Electrical Code requires that all 14/2 cables installed in homes have an outer jacket made of PVC (Polyvinyl chloride), a durable, flame-resistant material.

The presence of two hot wires makes 14/2 cable ideal for lighting circuits because it can safely handle up to 15 amps of current.

However, because it only has one ground wire, it’s unsuitable for circuits requiring grounding. If you need a grounded circuit, use a 14/3 or 12/2 cable instead.


  • 14-gauge wires are a choice for residential electrical wiring.
  • The wire is less expensive than 12/2-gauge wires and other thicker electrical wires.
  • It’s more adaptable, which makes it simpler to deal with.
  • A 14-gauge wire is also thinner than a 12/2-gauge wire.


  • When you plan to use your outlet for high-powered appliances like air conditioners or power tools, you will need to upgrade to a 12-gauge wire. You risk overloading the circuit and causing a fire.
  • If you ever want to update the outlet to 20 amps, you must rip out the 14-gauge wire and replace it with 12-gauge wire. It is a lot of electrical work, and it may be better to install a 12-gauge wire.

Safety Precaution

14-gauge wire and 15-amp circuits are inadequate to power many appliances and equipment people commonly use in their homes. These include window air conditioners, shop vacuums, and other devices that require 20 amps of power.

Outlets intended for these purposes must be connected to a 20-amp circuit. It is especially important in areas of the home where such devices are likely to be used, such as the kitchen, bathroom, outdoor areas, and garage.

To provide the appropriate amount of power to a 20-amp circuit, a 12/2-gauge wire must be used instead of a 14/2-gauge wire.

What Is 14/2 Wire?

14/2 wire is a three-wire jacketed electrical cable that contains 14-gauge wires. The first wire is black and is the “hot” wire. The second wire is white and is also a “hot” wire. The third wire is green or bare copper and is the ground wire.

This type of wire is typically used for household electrical wiring projects. It can be used for both 120-volt and 240-volt circuits. The jacket on the cable helps to protect the wires from damage.

What Is 14 2 Wire Commonly Used For?

14/2 wire is an electrical wire commonly used for outlets and lights on 15-amp circuits. It is also often used to power light that requires low amperage.

14/2 wire is made of 14-gauge copper wire and has two conductors (the thin wires that carry the electrical current).

The “14” in 14/2 refers to the gauge of the wire, and the “2” refers to the number of conductors. 14/2 wire is relatively thin and is not recommended for high-power applications.

What Is 14-Gauge Wire Used For?

14-gauge wire is most commonly used for light fixtures, lamps, and lighting circuits that carry up to 15 amps of current. 12-gauge wire is often used for outdoor receptacles and 120-volt air conditioners, as it can safely support up to 20 amps of current.

For larger appliances like electric clothes dryers, electric water heaters, and 240-volt window air conditioners, a 10-gauge wire is typically used, as it can handle up to 30 amps of current.

It is important to select a wire gauge appropriate for the current flowing through it to avoid overloading the circuit and creating a fire hazard.

What Is The Maximum Amperage 14/2 Wire Can Handle?

When working with electrical wiring, choosing the correct wire gauge for the amperage of your circuit is important. Otherwise, you risk overloading the wire, which can cause fires or other damage.

14/2 wire is best suited for circuits with an amperage of 15 amps or less. If you attempt to use 14/2 wire on a twenty-amp circuit, it will overheat and pose a serious fire hazard.

To be safe, always consult an electrician or reference a reliable guide before beginning any wiring project. With a little care and attention to detail, you can ensure that your wiring is safely installed and up to code.

Can You Run 14-Gauge Wire On A 20-Amp Circuit?

NO. 14 gauge is prohibited in any section of a 20 amp circuit. You need to use twelve-gauge wire for 20 amp circuits. It is for safety reasons. The American Wire Gauge (AWG) system defines the diameter of non-ferrous (i.e., aluminum and copper) electrical wire.

The larger the AWG number or wire “gauge,” the smaller the diameter; conversely, the smaller the AWG number, the larger the diameter. Most North American household circuits are rated for 15 or 20 amperes (A), with 120 volts (V) between conductors.

Depending on what you’re powering with your circuit, you’ll need to choose appropriately sized wires to prevent overheating and potential fire hazards.

In general, you’ll want to use lower-gauge wires for heavier loads, such as appliances, and higher-gauge wires for lighter loads, such as lamps and electronics. A 20-amp circuit should have 12-gauge wires; if you must use 14-gauge wires, don’t put more than three lights or outlets on them.

How Many Outlets Can You Put On A 14/2 Wire?

Electrical circuits are essential to any home, and it’s important to understand how they work to keep your family safe. One common question is how many outlets can be placed on a single circuit.

It depends on the wire size and amperage of the circuit. For example, a 14/2 wire on a Fifteen amp circuit can power eight receptacles. You can typically wire four outlets to a single 15-amp circuit using a 14/2 wire. If you need more outlets, upgrade to a larger wire size or add a new circuit. Remember that larger appliances, such as air conditioners and microwaves, may require their dedicated circuit.

Can 14/2 Wire Be Used For Lights?

The type of electrical wire you use for your project is important for safety and function. For projects that will be using 15-amp circuits, the 14/2 electrical wire is the best choice.

This type of wire is safe for both lights and outlets. It is the most common choice for low-amperage power light fixtures. When choosing electrical wire for your project, consult a professional to ensure you use the best type of wire for your needs.

Can You Wire Outlets With 14/2 Romex?

Romex is a type of electrical wiring that consists of two or more insulated wires, a bare ground wire, and a paper wrap. The most common type of Romex is 14/2, with two insulated wires (one black and one white) and a bare ground wire. 14/2 Romex can be used for any circuit that is 15 amps or less.

If you are wiring outlets on a circuit with amperage above 15 amps, you’ll need to use a heavier Romex cable to comply with the electrical code. Romex is easy to work with and is relatively inexpensive, making it an excellent choice for home wiring projects.

What Size Wire Should Be Used To Run An Outlet Circuit?

Most houses in the United States are wired with circuits that can handle 15 or 20 amps of current. To find out how much current your circuit can handle, look at the breaker or fuse that controls the circuit.

The number on the breaker or fuse will tell you how many amps the circuit can handle. If the number is 15 or 20, you can use either 12-gauge or 14-gauge wire for outlets on that circuit.

If the number is 20, you must use a 12-gauge wire for outlets on that circuit. A 14-gauge wire is unsafe on a 20-amp circuit because it can overheat and cause a fire.

Can 14 2 Wire Be Used For Outlets?

Outlets are necessary for any home electrical system, but what type of wire should they use? It depends on the amperage of the circuit. For example, you can use a 14/2 wire for outlets on a 15-amp circuit, but for 20-amp outlets, a 14/2 wire is insufficient. You will have to step up to 12/2 wire for all outlets on 20-amp circuits.

It is because the 14-gauge wire is only rated for 15 amps, while the 12-gauge wire is rated for 20 amps.

A wrong gauge of wire can cause overheating and even cause a fire, so choose the right one for your needs. Whenever in doubt, use thicker gauge wire and err on the side of caution.

What Happens If You Use 14 2 Wire On A 20 Amp Circuit?

Using 14-gauge wire on a 20-amp circuit can result in overheating and dangerous electrical fire. Before wiring an outlet, you should always find out how much amperage your circuit draws by checking your breaker box.

If you use a 14-gauge wire on a 20-amp circuit, you are exceeding the capabilities of the wire, and it could overheat. It could cause an electrical fire.

Should I Use 12 Or 14 Gauge Wire?

When wiring your home, you have a few options regarding the gauge of wire you can use. For light fixtures and lamps, you can use a 14-gauge wire. It is also appropriate for lighting circuits that carry up to 15 amps.

For kitchen outlets, bathroom outlets, and outdoor receptacles, you’ll need to use 12-gauge wire. And if you’re wiring a 120-volt air conditioner, you’ll need a 12-gauge wire that can support up to 20 amps.

Choosing the right gauge of wire is essential to ensuring the safety of your home’s electrical system.

How Many Outlets Can A 14/2 Wire Support?

The answer is eight receptacles or four outlet duplexes. It is based on the fact that each outlet typically has two receptacles and that 14/2 wire can support up to 15 amps.

Of course, this is just a general rule of thumb; the number of outlets a single circuit can safely power depends on the devices’ wattage.

However, four outlets per circuit is a good rule of thumb for most homes.

How Can I Determine My Circuit’s Amperage?

Calculating the amperage of a circuit is a simple process that can be done using a basic equation. First, determine the wattage of all devices plugged into the circuit.

For example, if calculating the amperage for a light bulb, look for the wattage listed on the bulb. Once you have the wattage of all devices, use the equation Amps = Watts/Volts to calculate the total amperage.

If you have a 200W light bulb and a 100W TV plugged into a 120V circuit, the equation would look like this: Amps = (200 + 100)/120= 2.5 amps.

It is important to always calculate the total amperage of a circuit before plugging in any devices, as this will help to prevent overloading and potential hazards.

Final Verdict: What Is 14 2 Wire Used For

14/2 wire is an electrical wiring used for low-voltage applications, such as in your home. It has two insulated copper wires with a total thickness of 14 gauge and can handle up to 15 amps of current. While it is generally safe to use, there are some safety precautions you should consider when working with this type of wire.
