ok, we installed a 2' x 3' j-box,we have 3 - 3" EMT'S on 1 side of box and 3 - 3" EMT'S on the opposite side of box " but" they are not directly across from one another they are "offset" a bit ,instead of a straight across from each other,in other words the wires will have a offset going into other conduits....dont you still classify that as a "straight pull" not a "angle " pull ???? *

so it should be 6x3=18+3+3 = 24" minimum size of box ...correct?

It would be (8*3")+3"+3"=30". You need to include the other conduits on the same side.

I agree, 30"

Do I need more coffee?:)

(1) Straight Pulls. In straight pulls, the length of the box
or conduit body shall not be less than eight times the metric
designator (trade size) of the largest raceway.

OP has 3" conduits in a straight pull. Why the extra addition for sizing?

Because I was stupid enough to post without reading :D
That has caught me before...apparently I'm a slow learner... the "additional conduits" appears in the angle and U pulls not the straight (go figure!!)..
24" would be adequate.



Thanks for watching my back.
 
My brain had skipped a memory cell; no additional adding needed for a straight pull. Sorry for the confusion. Yes, 24" is correct.
