What is the maximum trade size conduit permitted for enclosing a mobile home supply cord?

1 inch
1 1/4 inches
1 1/2 inches
2 inches

The correct answer is: 1 1/4 inches

The maximum trade size conduit permitted for enclosing a mobile home supply cord is 1 1/4 inches. This specification is outlined in the National Electrical Code (NEC), which provides guidelines for the installation of electrical systems, including the suitable conduit sizes for different applications. The reasoning behind allowing a maximum of 1 1/4 inches for mobile home supply cords is to ensure adequate protection and support for the cord while allowing for some flexibility in installation. Conduit larger than this may be unnecessary for the cables typically used in mobile homes, and using larger conduit could lead to additional costs and complications without providing significant benefits. Understanding the guidelines set forth in the NEC is crucial for ensuring safe and code-compliant installations. Such specifications are typically made based on the size and type of conductors used, potential voltage drop, and appropriate physical support for electrical components in mobile home applications.
