Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. Multiply the cable's length by its material's resistivity.
Can 12 gauge wire handle 30 amps?
A 30-amp breaker does not operate safely with a 12-gauge wire. The minimum wire size that is allowable for use with a 30-amp breaker is 10 gauge. A smaller gauge of wire indicates a larger diameter and the ability to carry more current safely. Twelve-gauge wire is acceptable with 20-amp or smaller circuit breakers.

THWN stands for "Thermoplastic Heat and Water-resistant Nylon-coated." THWN is a designation for a specific insulation material, temperature rating, and condition of use (wet locations) for electrical wire and cable.
Why is the wire gauge too small for a breaker?
But if the wire gauge is too small for your breaker, the current that flows through the wire is more than what it is designed to handle. Since the wire has a high resistance, heat is generated and this will eventually be enough to melt the wires.
What gauge wire do I need for a 30 amp breaker?
What gauge wire do I need for various different amps? The rule of thumb that techs will usually go by is that for a 30 amp circuit breaker, 10-gauge wire is the right size to go with. For a 40 amp you need a 8-gauge wire size and for a 20 amp, you will need a 12-gauge wire size.
How to find the amperage of a breaker?
If you have no idea where to find the amperage of your circuit breaker, look for the number on the handle of the breaker itself ; this number is the maximum amperage of that breaker. Once you find the amperage of your breaker, you can now determine what wire gauge to use.
Can a circuit breaker prevent a fire?
While circuit breakers have their own safety measures, such as tripping when it experiences an overload, this may not be enough to prevent a fire because of the wrong wire gauge used. These scenarios are totally avoidable, as long as you use the right wire gauge for a circuit breaker.
Can an electrician handle a circuit breaker?
While electrical work should ideally be handled by licensed electricians, it also helps to be personally aware of important aspects of your circuit breaker, such as the suitable wire gauge. To select the right wire gauge, professionals use different wire gauge size charts as their reference.
Can you use 12 gauge wire for a 25 amp breaker?
If you are wondering if your extra 12-gauge wire can also be used for a 25 amp breaker, it is possible to do so. A 12-gauge copper wire can be used if its ambient temperature rating is either 75 ℃ or 167 ℉ or 90 ℃ or 194 ℉, while a 12-gauge aluminum wire is compatible if its ambient temperature rating is 90 ℃ or 194 ℉.
