Question:
Hello Code Friends,
Is a listed fan box required if the support for the ceiling fan is provided by the structure and not the box?

A
Answer:
Thanks for the question Peter. The NEC requires listed fan boxes that are supporting the ceiling-suspended paddle fan. If the fan does not rely on the box for support, a standard box can be used at the outlet. Section 422.18 generally requires a ceiling suspended paddle fan be supported independently of the box, unless the box or box outlet system is listed for providing such support. See also Section 314.27(C) for weight limitations.
