Abstract
An electrical box with sidewalls having a front edge and a flange extending transversely from the sidewalls at a set distance from the front edge. Knockouts in the sidewalls include multiple removable sections, which can be removed selectively as desired to create large or small openings for electrical cables. The sidewalls of the electrical box include an opening therein and a panel that can be inserted into the opening. The panel includes an internal mounting arrangement with captive fasteners for securing the electrical box to a stud. The flange provides a sealing surface for contacting the vapor barrier surrounding the box and thereby seals around the periphery of the electrical box. Duct seal is applied around the periphery of the cables at the knockout areas to provide an airtight seal for the electrical cables entering the electrical box.
