Final answer:
The amp rating for 2 AWG aluminum wire, often used in residential wiring, typically ranges from 90 to 100 amps; however, checking the NEC and local codes is vital for specific applications.
Step-by-step explanation:
The amp rating for 2 AWG aluminum wire is not directly stated in the provided materials, but generally, an electrical wire's capacity to carry current is dependent on multiple factors which include its gauge, material, and the conditions of use such as the temperature and whether the wiring is in free air or in a conduit.
For 2 AWG aluminum wire, the ampacity can vary, but typically in residential wiring, it is rated for around 90 to 100 amps under normal conditions.
It's important to always check with the National Electrical Code (NEC) and local regulations when determining the appropriate ampacity for a specific application.
