Pull boxes where conduits Enter wall opposite removable cover

[jmac4949]

What size pull can will be required to accommodate 2 - 3" conduits and 1 - 1" conduit enter bottom of can and same conduits exit rear of can ( wall opposite removable cover)? Conductors are 250 mcm, 2 per phase.

This should help. Conductor size doesn't matter in the calculation

I don't agree with that drawing. The rule in the cited section requires that the distance between the conduits also be 6x the conduit trade size. That will require dimension B to be greater.

I agree with you. In fact the B dimension shown isn't even applicable in this case.

I agree also. I really never saw that but it makes sense otherwise you could install the conduit anywhere in the back. Has anyone mentioned this to mike? That drawing is almost 20 years old
