Which type of fitting connects two branch circuits to a single supply line?

The fitting that connects two branch circuits to a single supply line is known as a Tee fitting. This type of fitting is specifically designed to create a junction point from a single line, allowing the flow of fluid or electrical current to split into two separate branches. The "T" shape of the fitting facilitates the connection, with one inlet and two outlets, ensuring that both branch circuits can receive power or signal from the single supply line efficiently.

Using a Tee fitting maximizes the use of available resources in a system by allowing for the distribution of electrical power or fluids without the need for multiple supply lines, thus simplifying the overall design and reducing material costs. It is frequently employed in various applications, including plumbing, electrical systems, and other interconnected network structures.
