North Carolina Home Inspector Practice Exam

If you find aluminum wire on branch circuits in a house, what should you do?

1. Replace it immediately

2. Notate it for future reference

3. Note that a licensed electrician must evaluate the service

4. Ignore it if the wiring looks fine

The correct answer is: Note that a licensed electrician must evaluate the service

When aluminum wire is found on branch circuits in a house, noting that a licensed electrician must evaluate the service is essential due to the specific characteristics and risks associated with aluminum wiring. Aluminum wiring was commonly used in homes built from the 1960s to the early 1970s, but it poses different safety concerns compared to copper wiring, primarily due to its higher rate of thermal expansion and potential for creating loose connections, which can result in overheating and fire hazards. Having a licensed electrician evaluate the service allows for a comprehensive assessment of the wiring's condition. The electrician can inspect for any signs of wear, poor connections, or other safety issues, and recommend appropriate measures if deficiencies are found. This is important because while aluminum wiring is not inherently dangerous, it must be properly installed and maintained to ensure safety. By emphasizing the importance of professional evaluation, the correct approach ensures that any potential risks associated with aluminum wiring are appropriately addressed, thus protecting the occupants of the home and adhering to safety standards.
