Which type of electrical box is used specifically for fixture mounting?

The type of electrical box specifically designed for fixture mounting is the ceiling box, also known as a fixture box. This type of box is built to support the weight of light fixtures or ceiling fans and is often stronger and larger than other types of boxes. Ceiling boxes are equipped to handle the mechanical load and provide a safe and secure mounting point for fixtures.

On the other hand, other boxes serve different purposes. A Panduit box is typically used for raceway systems and organizing cables rather than for mounting fixtures. A cable box is designed for use with pull wires but does not typically provide the necessary support for fixtures. Lastly, a junction box is used primarily for connecting different electrical circuits and is not intended for mounting fixtures.
