Angle Pull Box Calculator
Angle Pull Box Calculator. The code specifies this based on whether it is a straight pull or the conductor turns in an angle or u pull. Factors you must consider include:

Calculate the minimum pull box width as six times the largest raceway size, plus the sum of all other raceways entering the same wall. Your pull box must be at least 16” wide. All fields are required in order to provide an accurate calculation.
All Fields Are Required In Order To Provide An Accurate Calculation.
When sizing pull boxes and junction boxes, follow these suggestions: Values provided cannot be a negative number, zero or a letter. 8'' x 2 = 16''.
Determine The Size Of Each Raceway You Will Be Using.
Calculate the minimum pull box width as six times the largest raceway size, plus the sum of all other raceways entering the same wall. Stainless steel 300 series weight calculate formula: How to find the tension force on an object being pulled is just like when the object is hung.
Tighter Sag Values, Clearing High Obstacles And Pulls Including Angles And/Or Elevation Changes Will Increase The Pulling Force Suggested Below.
The national electric code (nec) specifies a minimum size for pull, junction box and conduit bodies. Assume the following combination pull: • left to right angle or u.
The Maximum Incline Angle Is 30 Degrees Without Using A Cleated Belt.
Organize and always draw out the problem. Multiply the trade size (metric designator) of the largest raceway by eight. 8'' x 2 = 16''.
So The Box Should Be :
Determine if you need a straight or splice/angle/u pull, as you need to use different formulas. When pull boxes contain multiple rows. Now available for free download, greenlee’s new pullcalc app is the only pulling calculator on the market that finds the approximate pull force needed to install electrical cable inside conduit.
