Introduction of awg stranded wire + Best buy price
The AWG system is designed to indicate and categorize the stranded or solid wire and cable based on their sizes. different sizes of wire and cable have unique properties so their uses and applications may vary from one size to another size.
awg stranded wire
In each building, you must install wires and cables to meet electrical needs. You need to make sure to choose high quality wires for a safe electrical connection. You can choose cables based on different criteria.
One of them is wire gauge, also known as gauge. Different cables serve different purposes. In this article, learn more about thread gauge charts.
What is a wire gauge?
The thickness of the wire refers to the thickness of the wire. A number represents one meter. The higher the number, the thinner the line. The industry uses the American Wire Gauge method to measure the thickness of electrical wires.
The AWG method is a standard method developed in the USA. Using this method, you can specify gauges for solid, non-ferrous and round conductive wires.
According to the American Wire Gauge (AWG) method, the maximum wire gauge is No. 36 AWG, minimum gauge No. 0000. These are 0.005" and 0.46" in diameter respectively.
There are 40 gauges, or you could say 39 steps, between these maximum and minimum sizes.
The ratio between these two diameters is 1.92. Now, as the number of gauges decreases, the cross-sectional area increases. As a result, the diameter increases as the meter number decreases.
Now suppose that A and B are two consecutive gauges whose diameters are diameter A and diameter B. So for both the diameter ratio is 1.12293. Conversely, the percent diameter of a gauge two steps apart is (1.12293) ² ≈ 1.26098.
The relationship between thread gauge and other technical specifications
The thickness of the wire affects its electrical performance. Therefore, with the help of thread measuring instruments, the industry can determine whether the thread is suitable for its application.
Diameter: The wire gauge can vary from low to high. A decimal number represents a large diameter and a large number represents a small diameter.
For example, AWG 4 has a larger diameter than AWG 40. When the Gauge is reduced by six levels, the wire diameter doubles, meaning that the diameter of a four-gauge wire will be twice that of a tenth-gauge wire.
Area: You can calculate the cross-sectional area of a wire using the formula A= πr2. Here r is the radius (half diameter) of the wire. When the meter drops three levels, the cross-sectional area doubles.
Foot per Pounds: This means how many feet of thread you need to reach one pound. For example, an AWG 40 needs 34,364 feet to get one pound of weight.
Resistance (ohms/1000 feet): The resistance of the wire depends on thickness and length. The longer the wire, the higher the resistance. If the two wires are the same size, the thicker wire will have a higher resistance than the thinner wire.
For example, AWG 4 1000 feet has a resistance of 0.2485 ohms, while AWG 40 has a resistance of 1079 ohms at 25 degrees Celsius at 1000 feet.
Current Capacity (Amperes): The current capacity is the amount that an existing wire can safely carry. Cables with lower gauges (AWG 4) are thicker and therefore have higher current capacity.
Stranded wire AWG price
The price of wire and cable depends on its type and size, for example, copper wire has a price difference with aluminum wire, and the larger the size of the wire, the higher the price.
You can also use the AWG gauge to describe twisted wire. For stranded wire, the AWG gauge is the sum of the cross-sectional areas of each stranded wire. Here you do not count the distance between each chain.
If the twisted wire is made of round wire, the hole takes up 25% of the wire area. As a result, the entire wiring harness is 13% larger in diameter than solid wire of the same thickness.
To specify threads, mention three numbers. These include the AWG size, the AWG size of the strands, and the number of strands. For example, 22AWG 7/30 means 22 AWG stranded wire with seven strands of 30AWG wire.
Use a slash to separate the number of strands and the AWG of a single strand.
Differences in AWG affect the ratio of diameter to area. You can use this property to find the AWG of the twisted wire by diameter and number of wires. However, you can use it for a lot of the same round threads.
There is a direct relation between the sizes of wire and cable and their uses and applications. So, in this part we will name some of the mostly used wire sizes and their applications.
Typical applications for standard thread gauges
Different cables have different electrical properties, making them suitable for their unique applications.
Higher wire is suitable for light electrical engineering. On the other hand, lower thread wire is suitable for heavy projects.
For building and construction projects, the standard wire gauges are 10, 12 and 14.
Some other uses of wires of different gauges are-
18 gauge wire: you can use it for low voltage lighting applications and electrical wiring
16 gauge wire: This is great for lightweight extension cords.
Wire 14: You can use it for residential wiring, household plugs, electrical equipment and lamps.
Wire 12: You can also use it for wiring in homes, including smaller AC equipment and other appliances.
10-gauge wire: Because it is thicker, you can use it for larger appliances like water heaters, dryers, or window AC units.
Wire 8: You can use it for electric stoves and ovens.
Line 6: Line 6 is best for the largest household appliances, kitchen hobs and AC equipment.
Line 4 - Best for ovens and large heaters
Choose the perfect thread gauge
To select the perfect wire for your application, consider the carrying capacity and current (measured in amperes) that the wire must carry. The current you need to pass through the wire is directly related to the wire gauge.
The wire spacing you need will also affect the wire gauge. Since there is no perfect conductor, you will lose voltage with distance due to heat or resistance.
To counteract this effect, choose a larger thread. The high thickness of the wire will increase its current capacity. So you can draw the current you need without voltage drop.
We've talked about this before. But let's go into more detail to help you decide which thread gauge is best for which application.
Since we are confident that most of our readers are looking for wire gauge drawings for residential applications, we will use NEC Form 310.15(B)(16) (see table above) and take a conservative approach.
A conservative approach means taking the lowest rating for each AWG size. For example, according to our NEC chart, 14 gauge copper wire can hold 15 to 25 amps, depending on the temperature rating of the conductor (140ºF, 167ºF, and 194ºF, respectively).
To be careful, we stick to the lowest load that 14 gauge copper wire can handle, which is 15 amps.
So which thread gauge are you most likely to need?
Generally speaking:
14-gauge and 12-gauge copper wire are typically used for output circuits. It is best to use only AWG 14 wire in branch circuits rated at 15 amps or no more than 1,500 watts.
On the other hand, the AWG wire sizes 6, 8, 10 are suitable for larger appliances such as electric ovens, water heaters, air conditioners, heat pumps, etc.
Wire 4 and below are better for automatic feeders, depending on your load.
For service conductors, the wire or conductor should be no smaller than AWG 8 copper wire.
Bottom line: Residential wiring projects comply with the National Electrical Code. If you are unsure of the conductor temperature of your wire, we recommend using a conservative ampacity rating to avoid potential problems such as overheating and fire.
Avoid aluminum wire
Although it is not illegal to use aluminum wire in homes, we strongly recommend that you avoid it unless it is for specific applications.
Some examples include residential service entry lines and single-purpose high-current circuits such as 240-volt air conditioners or electric range circuits.
Does the wire meter affect amplifiers?
Yes. As shown in our previous line graph, AWG size has a negative covariance relationship with wire diameter (blue line) and ampacity (yellow line).
This means that wires with smaller AWG sizes must have larger wire diameters and vice versa. Thicker wires carry more current.
To help you remember this relationship, we can compare this concept to our water pipes. The lines are your pipes and the flow is the amount of water flowing through the pipes.
Larger diameter water pipes can deliver more water at any time. This concept also applies to wiring and ampacities.
Bottom line: The wire gauge affects the ampacity. Smaller AWG size means larger diameter and greater current carrying capacity.
What happens if I use a larger gauge than required?
To be clear, "use a larger wire gauge" means you are putting too much force on the wire.
Increasing the capacity has no serious consequences. It just costs more and may require adjusting the physical path of the wires (more strength means thicker wires).
But there are also advantages to using larger gauges. Larger diameter wires stay cooler due to low resistance. It is well known that the total resistance per unit length decreases as the wire diameter increases. This means less power consumption on your cables.
The formula for power consumption can be expressed as:
Current 2 times resistance (P= I2 x R).
The current applied to the wire causes it to heat up, meaning electrical energy is lost every second as heat.
Finally, using a larger AWG wire gives you more room to draw more current if you need it in the future.
Bottom line: Using thicker, higher ampacity wire costs more and requires a larger path. But they translate into lower resistance, less heat loss and more power savings. Not to mention, you can meet more power needs in the future without overhauling your wiring system.
Does the wire meter affect your electricity bill?
AWG size has a positive covariance relationship with resistance per length unit. So choose the most suitable type of wire for your consumption to save money.
Smaller AWG numbers have less resistance and will save you more money due to less power loss.
Household electricity consumption has increased dramatically since the 1930s. Therefore, it is sensible to check at regular intervals that the existing wiring is sufficient for the current.
While we touched on the basics of a wiring meter diagram, there are several factors to consider when dealing with electricity during home renovations.
We apologize if we have made you feel anxious in some parts of this article. We didn't put them there to scare you. Instead, we present them to give you an idea of the inherent safety risks and dangers of electricity.
That said, the last part is included to help impart advanced knowledge and keep you safe.
Safety first
Although we have covered the basics of AWG wire in this article, we strongly recommend that readers consult a professional when dealing with electricity. It's no secret that electricity can cause serious damage. Therefore, it should not be taken lightly.
Therefore, we recommend that you limit your DIY activities to low-energy projects. Repairs to main switch panels, service conductors, feeders, branch circuits, and similar electrical components (see diagram below) require NEC compliance.
