Abstract:
1. An electrical conduit system for encasing and protecting flexible wires or cables, said electrical conduit system comprising: a) a plurality of first conduit pieces, each first conduit piece having a first end with a first threaded region in a first thread direction and a second end with a second threaded region running in said first thread direction; b) at least one second conduit piece having one said first end with said first threaded region and one second end with said second threaded region, with a second thread direction being different than said first thread direction; and c) at least one coupling, said coupling comprising a first threaded portion and a second threaded portion, with said first threaded portion having a different thread direction than said second threaded portion, with said first threaded portion of said coupling configured to reversibly engage said first threaded region on said first conduit piece and with said second threaded portion of said coupling configured to reversibly engage said second threaded region on said conduit piece, acting to reversibly couple said first conduit piece with said second conduit piece; wherein said coupling insures abutment of said ends of said two conduit pieces, providing an electrical ground which passes through said conduit piece ends, but does not pass through said coupling; d) at least one locking ring, having a circular inside, and said locking ring comprising a coarse threaded portion, said coarse threaded portion being oriented on said circular inside of said locking ring, and said coarse threads being aligned perpendicular to said circular inside, with said locking ring being formed to less than 360° and formed from a spring steel of suitable hardness; wherein said electrical conduit system further provides the specified amount of thread engagement to meet various sealing and cooling capabilities required by the various electrical codes in their stricter requirements, and said electrical conduit system further provides a conduit installation that is not larger than any part of a normal installation, a normal installation being a common and appropriate size for the particular location and type of installation as generally understood and known in the art, and which allows the closes parallel conduit runs allowed within the size of conduit run.
