To give an approximation of the pull force that will be required to install electrical cable into a conduit, there are
many unknown factors involved that prohibit giving exact results. Most notable amongst these is the coefficient
of friction, occupancy of conduits (existing cables), lubrication, surface texture, and lay of the cable are never
uniform along the length of a conduit run.

Comparing the known forces of pulls against the estimated force can give you a guide as to a good coefficient of
friction to use for similar future pulls. In lieu of this, the Greenlee suggest some starting points for coefficient of
friction of well-lubricated cable.
Typically known as a “leg”, is a straight run of conduit followed by a bend, except for the last Leg, which would
typically have no bend. Obviously there can be numerous bends in the run. If the leg changes elevation, there
are substantial effect multipliers for vertical rise or descent. The total cable weight and a coefficient of friction are
required. If there is a known drag on the cable before it enters the conduit, that force can be entered in and the
estimated pull force can be displayed.
