Which of the following can be categorized as a fitting?

A conduit connector is categorized as a fitting because it serves a specific purpose in connecting sections of conduit together or connecting conduit to an electrical enclosure. Fittings are essential components that facilitate the routing of electrical wiring and ensure safe and effective connections within electrical systems.

In contrast, a switch functions as a control device that interrupts the flow of electricity, an outlet is a point in the wiring system where electrical devices can be connected to draw power, and a breaker is a safety device that protects circuits from overloads or short circuits. These other components do not serve the purpose of connecting conduit sections or adjusting the direction of conduit runs, which is the primary function of a conduit connector.
