Abstract:
1. A system for installing electrical wiring into electrical conduit, the system comprising: a vacuum source having a hose; a conduit interface tube; a lightweight pulling line that is drawable through the electrical conduit by the vacuum source; an integral, one-piece adapter having a first connector segment extending inward from a first end of the adapter wherein the first connector segment receives an extent of the hose, the adapter further having a second connector segment extending inward from a second end of the adapter wherein the second connector segment receives an extent of the interface tube, the adaptor further having a transition segment positioned between the first and second connector segments, the transition segment having a diameter less than a diameter of both the first and second connector segments; wherein the first and second connector segments and the transition segment collectively define an internal air passageway that extends between the first and second ends of the adaptor; and, wherein the hose extends between the vacuum source and the first connector segment of the adapter, and wherein the interface tube extends between the second connector segment and the electrical conduit through which the electrical wire is introduced.
