splice box

[olly]

I have a Mike Holt work book on order, can someone tell me how to size a splice box when you have a 2" and a 1 1/4 terminating on the same end of a splice box. No other conduits.

I believe its 2" x 6 which would mean I need a 12 X 12 box. Is that correct

Conductors are being spliced and not just looped through ?

314.28(A)(2) --> 2" x 6 + 1.25" = 13.5" to the opposite wall.

And applies if conductors are 4AWG or bigger.
