Electrical junction box with fastener knockout feature and method
First Claim
1. A junction box assembly for providing an air impermeable barrier between a box support structure and a junction enclosure, the junction box assembly comprising, in combination:
- at least one fastener and an electrical junction box, said fastener having a fastener head, the junction box comprising a base plate and a peripheral wall, the peripheral wall extending from the base plate such that the base plate and peripheral wall define the junction enclosure, the base plate comprising a series of fastener-receiving apertures and a series of fastener-based aperture-covering slugs, the fastener-based aperture-covering slugs being attached to the base plate adjacent the fastener-receiving apertures thereby covering the fastener-receiving apertures and providing said air impermeable barrier, the fastener-based aperture-covering slugs being selectively detachable from the base plate via an implement for selectively exposing the series of fastener-receiving apertures, the selectively exposed fastener-receiving apertures for receiving said fastener, said fastener head for re-sealing the selectively exposed fastener-receiving apertures when fastening the junction box to the box support structure thereby providing said air impermeable barrier between the box support structure and the junction enclosure.

Abstract
A Chicago-style plenum-type electrical junction box provides an air impermeable barrier between a box support structure and a junction enclosure. The junction box includes a base plate and a peripheral wall, the peripheral wall extending from the base plate such that the base plate and peripheral wall define the junction enclosure. The base plate preferably includes a series of fastener knockouts so as to provide an air impermeable barrier. The fastener knockouts are selectively removable for exposing a series of fastener-receiving apertures. The fastener-receiving apertures receive a series of fasteners for sealing the fastener-receiving apertures when fastening the junction box to the box support structure thereby providing an air tight barrier between the box support structure and the junction enclosure.

9. A method for installing an electrical junction box so as to provide an air impermeable barrier adjacent a box support structure, the method comprising the steps of:
- forming a fastener-based aperture-covering slug in a junction box base plate such that the fastener-based aperture-covering slug provides said air impermeable barrier;
detaching the fastener-based aperture-covering slug from the junction box base plate via an implement thereby exposing a fastener-receiving aperture;
positioning the junction box base plate adjacent the box support structure;
inserting a fastener into the fastener-receiving aperture;
fastening the junction box base plate to the box support structure via the fastener; and
re-sealing the fastener-receiving aperture via the fastener thereby providing said air impermeable barrier adjacent the box support structure. - View Dependent Claims (10, 11, 12, 13)

14. A method for installing a barrier structure upon a support structure so as to provide an air impermeable barrier adjacent the support structure, the method comprising the steps of:
- removing a preformed, fastener-based aperture-covering slug from said air impermeable barrier structure thereby exposing a fastener-receiving aperture;
positioning the barrier structure adjacent the support structure;
inserting a fastener into the fastener-receiving aperture;
fastening the barrier structure to the support structure via the fastener; and
