How to determine the best wire gauge?
You can use a common wire stripper, however, to determine the diameter or the gauge size of the wires. Most wire strippers have a series of round holes labeled with AWG sizes where you can insert the wires. You not only can strip wires of a specific size but can also determine the gauge size of the wire.
How to tell what gauge wire you have?
Method 3 Method 3 of 3: Gauging Stranded Wire
- Measure the diameter of a single wire. Stranded wire consists of multiple thin wire filaments that have been twisted together to form a single composite "wire."
- Multiply the wire’s diameter by itself. To calculate the gauge of stranded wire, you’ll need to double the diameter.
- Multiply the result by the number of strands in the wire. ...
What is meant by the gauge of an electrical wire?
Wire gauge is a measurement of a wire, either its diameter or cross-sectional area. The gauge of a wire determines how much current can flow through the wire. The gauge also determines the resistance of the wire and its weight per unit of length. When dealing with wire gauge, the characteristics of a wire usually specified on a chart is the ...
What gauge wire should I use for my amp?
- If you rarely use your amp or stereo output above 50%-60% power, you can go down one wire AWG gauge. ...
- Have extra wire you’d like to put to good use? ...
- For surround sound and center channel home theater speakers, you shouldn’t spend a lot because their power needs are usually fairly low.
Is a higher wire gauge better?
In general, a lower AWG number is better than higher AWG. AWG is of primary importance for wires that will carry electrical power -- for example, home or business electrical wiring, extension cords or high-power wire in automotive or audio use.
Which is thicker 12-gauge or 14 gauge wire?
Twelve gauge is about the thickness of a nickel, and 14-gauge is about the thickness of a dime. Also, look at the breaker for the circuit in question to see if it's a 15-amp or a 20-amp breaker. A 20-amp circuit requires wire that's 12-gauge or larger.
Which is thicker 8 gauge or 10 gauge wire?
The general rule of thumb is that the smaller the gauge number, the thicker the cable.
How do I know what gauge wire to use?
To determine what gauge wire you need, consider the carrying capacity and the amount of current the wire needs to conduct (measured in amperage or amps). Wire gauge is directly related to how many amps you need to run through it. The distance you need the wire to go can also impact the gauge of wire you need.
Is it OK to use 12 gauge wire on a 15 amp circuit?
However, 12-gauge wire is acceptable on both 15- and 20-amp circuits, so some electricians use it exclusively when wiring a house. This avoids the potential for mixing wire gauges in future repairs or additions, which is prohibited by the National Electric Code because it's a fire hazard.
Can 14 gauge handle 20 amps?
NO. 14 gauge is prohibited from use in any section of a 20 amp circuit. You need to use 12 gauge wire for 20 amp circuits. This is for safety reasons.

RULES OF THUMB “Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
What happens if wire gauge is too big?
If a wire gauge is “too big” then it is a lot more expensive and is harder to bend, as well as more difficult to attach with wire nuts or to switches. Other than that, not much of anything.
What size wire do I need for 50 amps?
6For a maximum of 50 amps, you'll need a wire gauge of 6. Fifty amp breakers are most often used to power many different appliances. However, a kitchen oven can alone require 50 amps.
Can I mix 12 and 14 gauge wire?
Certainly, but you shouldn't exceed the current capacity of the smaller conductor. In this case, the 14 gauge wire, which in the US at 120V is typically rated at 15 Amps. (12 AWG is rated at 20 Amps.)
What happens if wire gauge is too small?
Using a wrong wire gauge leads to heat resistance, which can quickly turn into a fire hazard. Notably, each cable is designed to accommodate a specific amount of voltage ideal for a given application. If you use an inappropriately sized wire, it may end up melting due to the high amounts of flowing current.
Can you use 12 gauge wire on a 30 amp circuit?
No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps.
Is higher gauge wire thicker or thinner?
Wire/cable thickness is defined in terms of gauge. Generally speaking, the smaller the gauge number, the thicker the cable. The standardized method of measuring the thickness of a cable (American Wire Gauge or AWG) was established in 1857 in the United States.

What does the gauge of a wire tell you?
The gauge of the wire tells you how much current can safely pass through it. If you don’t use the right size, you’re at risk of overheating and burning if there’s a short circuit. Using the wrong wires is a fire hazard. Here are some interesting facts about the AWG:
What is the most common gauge of wire?
The most common sizes of wire gauge include 2-, 6-, 8-, 10-, 12- and 14-gauge wire. The term “gauge” is used for wire up to 1 AWG. The term “zero” is used for a wire that’s 1/0 AWG and larger. A wire that is “true to gauge” meets or exceeds the diameter of the copper for its AWG rating.
How Are Wires Measured?
All wires in the US and the UK use the system called American Wire Gauge (AWG) to measure the thickness of currency-carrying wires and cables. This measuring system first came into use in 1857. It’s the standard that every wiring and electrical job uses to select the proper wires for every project.
What is the ampacity of a wire?
Ampacity is the measure of electrical current that can pass through a wire. In general terms, the lower the gauge size, the higher the ampacity. For example, you can safely use 15 amps in 14-gauge wires, 20 amps in 12-gauge wires and 30 amps in 10-gauge wires. When you set up an electrical system, the ampacity should match the amps ...
What are the different sizes of wire?
Here are some interesting facts about the AWG: 1 The most common sizes of wire gauge include 2-, 6-, 8-, 10-, 12- and 14-gauge wire. 2 The term “gauge” is used for wire up to 1 AWG. 3 The term “zero” is used for a wire that’s 1/0 AWG and larger. 4 A wire that is “true to gauge” meets or exceeds the diameter of the copper for its AWG rating. 5 As the number gets smaller, the size of the wire gets larger and the amount of amps it can handle also increases.
What is the best wire for a car?
Stranded wires are stronger and more flexible. They are a good choice for wiring in cars and heavy-duty machines where they can stand up to constant vibration. Single-strand wires tend to be stiff. They are best in residential construction because they’re less likely to split and fray.
What does gauge number mean on cable?
Generally speaking, the smaller the gauge number, the thicker the cable or wire. The measurement does not include any outer insulation, wrapping or protective cover. It only includes the actual conducting wire itself.
What is the gauge of wire used in a home theater?
A wire gauge refers to the size of the copper wires used in your home theater. In America, the size of the gauge determines the diameter of the wire in millimeters as well as the cross-sectional area of the wire. Common sizes usually starts at 10 American Wire Gauge, or 2.588 millimeters in diameter. The diameter of the wire gets smaller as the gauge size gets higher. For example, a 10 gauge wire is much thicker than a 20 gauge wire.
How to determine speaker wire size?
Usually, you select the size of the wire gauge based on the length of the wire. If you need the wire to stretch a long distance around the space, then you may want a thicker diameter because it has a lower resistance to the flow of the electrical current. A short run may benefit from a 16 gauge wire because the current does not travel as far. You also want to consider the number of ohms on your speakers. If you have a low impedance speaker system with 4 or 6 ohms, then you want a 10 or 12 gauge wire. If the system has 8 ohms or higher, then you may benefit from 16 or 18 gauge wires.
What color are banana plugs?
Use one color for a specific polarity to prevent mix-ups or complications with the home theater system. In most cases, the red banana plug goes with the positive charge while the black banana plug goes with the negative charge. You need to evaluate your specific banana plugs to determine if color coding is an option or if you need to determine an alternative way to keep your wires organized.
