Product Information

The higher the number - the thinner the wire. Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 20 amps is 14 AWG wire. Color-coded Polyvinyl Chloride (PVC), heat and moisture-resistant, flame-retardant compound per UL-1063 and UL-8 4 AWG THHN/THWN-2 Specifications*: gauge wire has a rated ampacity of 17 amps at 75°C. That means it can handle 15 amps well, for example, since it is limited by the maximum current of 17 amps.

AWG sizes do not fit perfectly into mm or inches, so you may need to round up or down when safe to do so.What really determines the amperage, apart from the metal used to make a wire out and temperature, is the cross-section. 6 gauge wire has a cross-section of 13.3 mm2. This allows for a sub-100 amp electric current flow. gauge electrical wire can also be used as an 18 gauge stranded wire; for thermostats wiring, for example. You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 25 amps is 12 AWG wire.

For wires that carry signals, such as video interconnect or audio hookup wires, the AWG is not as essential as it is for power wires. It is because the electrical signals in these wires have low power, and thus you do not need smaller AWG wires. Cable pair twisting and efficient shielding are more critical in these wires to maintain the integrity of the signals. In the AWG system, the wire diameter doubles with every 6 gauge reduction, and the cross-section area doubles with every three gauge reduction. AWG to Cross-sectional area If you need a wire to handle a certain amount of amps you can just scroll down to the appropriate subchapter that covers the amperage you’re interested in. The AWG table below is for a single, solid, round conductor. Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter.

Resistance Notes: The resistance noted in the table above is for copper wire conductor. For a given current, you can use the noted resistance and apply Ohms Law to calculate the voltage drop across the conductor. AWG wire has an ampacity of 11 amps at 75°C. That means that it can normally conduct 11 amps of electrical current.

We’ll start with the 10 amp wire size and work our way to the 200 amp wire size: 10 Amps Wire Size: AWG Gauge, Breaker, Suggestion For 110V-120V Circuit AWG gauge battery cable (even a 12-volt battery can generate up to 1,380 W; that’s the maximum capacity of the 2 gauge battery cable on a 12-volt circuit). Let’s cover the basics of 10 gauge wire in mm and mm2. 10 AWG wire has a diameter of 2.588 mm and the diameter of 5.26 mm2. Most 3/0 gauge wires with 85.00 mm2 cross-section are rated up to 600 volts. They can work in temperatures between -58°F and +221°F. gauge wire is one of the most popular low voltage (12V, 24V) AWG wire. It has several applications that correspond to low voltage battery electronic devices. Stainless steel variety is commonly used as a 20 gauge wire for jewelry making, for example.

Batteries have a 12V circuit. 16 gauge wire amps at 12V are the same; 17 amps. That means that a 16 gauge wire can handle 204 watts with a 12V battery. You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 200 amps is 3/0 AWG wire. As aluminum is not as good as copper in its conductivity, we consider aluminum as two gauges larger than copper when we compare the conductivity of both.

gauge battery cable (In a 12V battery, you can get 12Vx65A = 780 watts. In a 24V battery, you can get 1,560 watts). Similar to the 4/0 gauge wire, the 3/0 AWG gauge wire is used for welding and for drawing the current (and power) out of large 12-volt or 24-volt batteries.The number of devices connected to the circuit usually determines how much current will flow through the wire. In short, 12 gauge wire can handle 25 amps; it has an ampacity of 25A at 75°C. It’s many times used as your go-to 20 amp size wire for a number of different applications. If you’re looking for wire size for a 60 amp circuit (this can be for a 60 amp 220-volt circuit, breaker, battery output), you will need an AWG with at least 60 amp rated ampacity at 75°C. You can consult the wire ampacity chart from the 1st Chapter and see that the most appropriate wire size for 10 amps is 20 AWG wire. In the subchapter below, you will find adequate wire sizes for 10 amps, 15 amps, 20 amps, 25 amps, 30 amps, 40 amps, 50 amps, 60 amps, 70 amps, 80 amps, 90 amps, 100 amps, and 200 amps.
