What is the typical temperature rating for residential wiring insulation?

• A. 60 degrees Celsius (140 degrees Fahrenheit)
• B. 75 degrees Celsius (167 degrees Fahrenheit)
• C. 90 degrees Celsius (194 degrees Fahrenheit)
• D. 100 degrees Celsius (212 degrees Fahrenheit)

Answer: (A)

The typical temperature rating for residential wiring insulation is 60 degrees Celsius (140 degrees Fahrenheit). This rating is commonly associated with older types of insulation materials such as those used for non-metallic sheathed cables (e.g., NM cable). While other options represent higher temperature ratings that may apply to specific applications or types of wiring (like those designed for industrial use), residential wiring primarily relies on insulation that is rated for 60 degrees Celsius to ensure safety and compliance with building codes. Selecting this option indicates an understanding of standard practices and safety measures in residential electrical installations.
