You are talking of two different things here. The voltage rating of a wire is based on the insulation factor. Common wire voltages are 300, 600 and 1000 volts. Current rating of a wire is based on the diameter of the wire and measured in AWG. The electrical code states how much current can be legally applied to the wire. Answering your question, the 2 wire cable is probably 300 volt rated and your #14 size wire is rated at 15 amps. Code also states that conductors can only be loaded to 80% continuous load, so 15 x .8 = 12 amps.

ProfessorA 14-2 wire typically corresponds to a 15 Amp rating in most residential settings, as it is commonly used for general lighting and outlet circuits. However, it is crucial to consult the local electrical codes and consider the specific application to ensure that the wire's ampacity meets the requirements for safety and performance.

What is the amp rating of NM wire?
The amp rating of NM (Non-Metallic) wire varies depending on the gauge of the wire. For example, a 14-gauge NM wire typically has an amp rating of 15 amps, while a 12-gauge NM wire has an amp rating of 20 amps. It is important to consult local building codes and regulations to determine the appropriate wire gauge and amp rating for specific applications.
What is amp rating for 16 gauge wire?

What is the 16 gauge amp rating?
A 16-gauge wire typically has an amp rating of around 10-15 amps, depending on the type of insulation and wire composition. It is important to consult the manufacturer's specifications or a professional electrician to ensure safe and proper usage.
What is the amp rating for a 3 wire?
A 3-wire circuit could have different amp ratings depending on the type of wire and the application. In residential settings, a common amp rating for a 3-wire circuit is 20 amps, which is typical for general-purpose lighting and outlet circuits. It's important to consult the local electrical code or a professional electrician to determine the appropriate amp rating for a specific 3-wire circuit.
Can you hook a 15 amp and 20 amp breaker to a breaker box using 20 amp wire?
No, you should use wire that matches the lowest amp rating of the breakers connected to it. In this case, you should use 15 amp wire since one of the breakers is a 15 amp breaker. Matching the wire gauge to the lowest amp rating ensures the wire is protected from overheating in case of a short circuit.
