Can a soffit or a box out be built around duct work that is in the dedicated space over a panel?
Is a framed and gypsum board finished ceiling considered a structural ceiling?
A short description:
A panel is surface mounted on a wall. The dedicated space is 6' from the top of the panel for the width of the panel and the depth of the panel. A 3'x3' duct comes through the wall 5' over the top of the panel. This duct is in the dedicated space. Can a framed and gypsum board finished box around the duct work be considered a structural ceiling? (therefore meeting the requirements of 110.26E 2014 NEC)
