ABSTRACT:
A method of routing rigid electrical conduit pipe between spaced apart enclosures includes measuring the distance between the enclosures and cutting a length of conduit pipe to the measured distance, less a bulkhead hub allowance. Bulkhead hubs are threaded onto each end of the cut length of conduit pipe, to make a conduit assembly. O-rings are contained at the end faces of each bulkhead hub. The conduit assembly is positioned between the enclosures having aligned openings. Inner hubs also having o-rings within a recess are threaded into the bulkhead hubs from the inside of each enclosure, forming a sealed electrical conduit pipe connection between the enclosures.
