Therefore, if we were to connect a 10kΩ resistor to this wire, it would have a voltage of 10V, which means that it can carry 10A of current. This is because the voltage across the capacitor is equal to the resistance divided by the value of the resistor. If we connect the wire to a 5V power supply, the current will be 1A. For ex ample, let’s say we have an 8- gauge wire with a resistance of 1 ohm and a capacitance of 0.1uF. Since 8 gauge wires can capably carry 40 amperes, we can determine the maximum current that can be carried by a single wire. What size breaker do I need for 8 3 wire? For ex ample, a 1/4″ gauge wire will measure 1.5″ in diameter from center to center. The gauge is measured from the center of one end to the other end. Gauge is a measure of the diameter of a wire. It is available in a variety of diameters and thicknesses. One of the most popular single conductor copper wire is the #8 gauge. That’s a lot of extra water to carry around. If you were using an 11.1 volt battery and wanted to discharge it down to 9.2 volts and then recharge it back up to 10.3 volts using 5 amps, that would require a 9-gal. If you are using a 12-volt battery, the voltage rating of the battery will determine how much current you will be able to draw.įor ex ample, if you have a battery rated at 12 volts, and you want to charge it to 12.5 volts with a 5- amp circuit, then you would need to use a 6- or 7-ga. You need more than a 4- gauge wire to handle the load. Can I use 8-gauge wire on a 30 amp circuit?Īn 8- gauge copper wire can carry 50 Amps at a temperature of 167 degrees F while an 8- gauge aluminum wire can only carry 40 Amps.How far can you run 8-gauge wire for 30 amps?.What size breaker do I need for 8 3 wire?.
