What is one of the four ways to connect a conduit to a box?

Connecting a conduit to a box can be achieved through various methods, one of which involves using adapters. Adapters serve as critical components during electrical installations, allowing for the smooth transition between different sizes or types of conduits and connecting them to junction boxes, outlet boxes, or switch boxes.

This process is essential for maintaining the integrity of the electrical system, ensuring connections are secure and can accommodate changes in conduit sizes or configurations. Adapters are specifically designed for this purpose, ensuring that the connection is both compliant with electrical codes and safe for use, minimizing the risk of damage or failure.

The other options do play roles in the broader context of electrical installations, but they do not specifically address the method of connecting a conduit to a box. Fasteners, for instance, may be used in various contexts to secure components but are not uniquely designated for conduit-to-box connections. Seals are essential for preventing moisture ingress but do not facilitate the connection itself. Brackets might help support conduits but are not meant to connect them to boxes. Thus, adapters are the clearly defined solution to properly connecting a conduit to a box.
