What is the primary purpose of a T-type conduit body in electrical installations?

The primary purpose of a T-type conduit body in electrical installations is that it serves as a junction point for connecting two or more conduits. This type of conduit body is specifically designed to facilitate the changing of direction in conduit runs or to create branch circuits, allowing for more effective management and routing of electrical wiring. The T-shaped design provides a pathway for the conductors while ensuring that they are adequately protected and organized.

While other options may relate to different components of electrical installations, they do not accurately represent the specific function of a T-type conduit body. For instance, while a junction for wiring connections can occur in a conduit body, that is typically not the primary purpose for a T-type body, which is more focused on facilitating conduit connections. Supporting lighting fixtures relates more to mounting hardware rather than conduit bodies, and reducing electrical resistance pertains to the properties of the conductors themselves rather than the conduit body.
