511.9 If a conduit does Not pass thur a Classified area sealing is Not required. See page 771 Exhibit 511.1. If a conduit comes from Outside the building goes up to 28inches then enters a box inside a poured concrete wall it never enters the classified area. Thus Seal not required. Whatca think?? Same as example on page 771 but conduit comes from outside & stays inside the outer wall. Yoopers
