Pull and Junction Boxes and Conduit Bodies

[dpenbert]

How does one size a pull box that contains one angled pull and two straight pulls, where all three raceways contain conductors 4 AWG or larger?

Hello,

I see that for angled pulls you multiply 6 times the largest raceway and for straight pulls you multiply 8 times the largest raceway. I have both types of pulls going into the pull box, so your saying I need to multiply the largest raceway by 6 and ignore the requirement for straight pulls?

Thanks

Do both calculations and use whichever results in the greater dimensions.

Ed,

That is what I was thinking as well.

Thanks.
