Note
To prevent conduit connectors from seizing in the threads of the conduit openings, apply
a conductive anti-galling compound to the threads, or wrap threads with PTFE tape two to
three layers deep.
Wrap the tape in the opposite direction that the male threads will turn when inserted into
the female conduit opening.
