Final answer:
The temperature rating to be used when selecting AWG size for wiring ceiling outlet boxes depends on the specific application and the relevant electrical codes. In general, a temperature rating of 60°C (140°F) is commonly used for residential wiring.
Step-by-step explanation:
The temperature rating to be used when selecting AWG size for wiring ceiling outlet boxes depends on the specific application and the relevant electrical codes. In general, for residential wiring, a temperature rating of 60°C (140°F) is commonly used. However, in certain cases where higher temperatures are expected, such as in commercial or industrial settings, a temperature rating of 75°C (167°F) may be required.
It's important to follow the appropriate electrical codes and regulations in your region to ensure safe and proper wiring installations. These codes will provide specific guidelines for selecting the appropriate wire size and temperature rating based on the intended use and environment.
For example, in the United States, the National Electrical Code (NEC) provides detailed requirements for electrical installations, including temperature ratings for wiring. Local building codes may also have specific requirements, so it's important to consult with a qualified electrician or refer to the applicable electrical codes.
