What type of box serves to join different runs of raceways while providing space for connection of conductors?

A junction box is specifically designed to facilitate the joining of different runs of raceways while providing a designated space for the connection of conductors. Its primary function is to house electrical connections and protect them from environmental elements and physical damage. Junction boxes are essential in electrical installations to ensure that connections are secure and accessible for maintenance or modifications.

In addition, junction boxes allow for the efficient routing of electrical wires and can accommodate various wiring scenarios, making them versatile for residential, commercial, and industrial applications. They often have covers to keep the internal connections safe, preventing accidental contact and ensuring compliance with electrical codes.

This design is distinct from the other types of boxes mentioned. For instance, a pull box is primarily used in situations where conductors need to be pulled through longer distances or in cases where there are bends in the conduit system, but it does not serve as a connection point in the same way a junction box does. Utility boxes and service boxes may also have specific functionalities related to utilities or service connections but do not specifically focus on joining raceways and connecting conductors.
