Often times my project manager will insist that I use a gutter in lieu of a LB, to save money of course.
My question is how to interpret table(s)
373-6(a) and 373-6(b).If for example I were to enter the end plate of a gutter with 4 250mcm cables and exit through the back wall,I beleive I would use table (a). Would I go to the 4 wires per terminal column and use a 10x10 gutter with a lenght of 6x the conduit size?
Also If I bring my feeders into the top of a panel with lugs on the bottom do I need to use this table to determine if I have enough space to bring my cables down along the side and then bend 180 degrees up to the lugs?
thanks in advance, Barry

Barry,
Look at the exception to 373-28(a)(2). It tells you to use the "one wire per terminal" size from Table 373-6(a).
