The present invention is related to passages for electrical wires, and more specifically, to a branch block that allows various conduits to be joined while the wires and connections remain separated throughout their path, while and after passing through the branch block. A branch block is generally constructed as a parallelepiped having a plurality of sidewalls, a top wall, and a bottom wall to form a water resistant enclosure having at least one inlet conduit port that branches into two or more independent channels terminating in outlet conduit ports. The diverging nature of the branch points allow wire to be pulled through an outlet conduit, the branch block, and the inlet conduit without opening the branch block. In addition, the wires are generally separated as they pass through the branch block, eliminating cross signals. This construction also provides a sealable structure that is suitable for wet or explosive environments.
