Title: Water resistant supplementary joint cover for an electrical busway
Inventor: BRYANT AUBREY
IPC: H02G5/00
Filed: 1994-05-17
Abstract: ABSTRACT This present invention provides an inexpensive and easily installed supplementary joint cover system for preventing dripping or splashing water from entering the joint between two adjacent sections of electrical busway. The joint cover system includes four dam assemblies, four sealing strips, two cover plates, two inspection hole plugs, and two connecting channels.  Each of the two adjacent busway sections requires two dam assemblies to seal the busway housing at the joint.  The dam assemblies form a water resistant block in the troughs formed by the busway housing.  The sealing strips are placed across the dam assemblies and provide a seal for the cover plates.  The connecting channels have a cross-sectional shape which cooperates with the busway housing sides such that the connecting channel nests with the busway housing side.  A water resistant gasket is attached to a nesting side of the connecting channel.  As the connecting channel is tightened against the two adjoining busway housing sides it compresses the water resistant gasket sealing the two adjoining busway housing sides and the two cover plates against the ingress of water.
