Wire Pull Force Calculator

Wire Pull Force Calculator:

Enter the values of coefficient of friction, u, diameter of the wire, d_(in), length of the pull, L_(ft), material factor, M and gauge of the wire, I to determine the value of Wire pull force, WPF_(lbs).

Enter Coefficient of the Friction :
Enter Diameter of the Wire :		in
Enter Length of the Pull :		ft
Enter Material Factore :		m
Enter Wire size :		G
Result – Wire Pull Force :		lbs

Wire Pull Force Formula:

The wire pull force calculation estimates the force needed to pull electrical wire or cable through a conduit or duct, considering factors like the frictional resistance, wire size, pull length, and wire gauge.

Wire pull force, WPF_(lbs) in pounds is equated by dividing the product of coefficient of friction, u, square of diameter of the wire, d_(in) in inches and length of the pull, L_(ft) in feet by material factor, M and gauge of the wire, I.

Wire pull force, WPF_(lbs) = u * d²_(in)* L_(ft) / M * I

WPF_(lbs) = wire pull force in pounds, lbs.

u = coefficient of the friction.

d_(in) = diameter of the wire in inches, in.

L_(ft) = length of the pull in feet, ft.

M = material factore.

I = wire size in gauge, G.

Wire Pull Force Calculation:

1. Determine the Pull Force for a 0.1-inch Diameter, 14 Gauge Wire Over 200 Feet.

Given: u =0.3, d_(in) = 0.1inches, L_(ft) = 200ft, M = 0.8, I = 14.

Wire pull force, WPF_(lbs) = u * d²_(in)* L_(ft) / M * I

WPF_(lbs) = 0.3 * 0.1² * 200 / 0.8 * 14

WPF_(lbs) = 0.0535lbs.

2.Suppose you need to calculate the gauge of a wire based on the following known parameters:

Given: u =0.2, d_(in) = 0.25inches, L_(ft) = 100ft, M = 1.0, WPF_(lbs) = 5lbs.

Wire pull force, WPF_(lbs) = u * d²_(in)* L_(ft) / M * I

I =u * d²_(in)* L_(ft) / M * WPF_(lbs)

I = 0.2 * 0.25² * 100 / 1.0 * 5

I = 0.25.
