Enclosure assembly with housing
Enclosure assemblies employed in electrical installations, including those employed in solar power installations, which conform to NEMA 3R type rating defined by National Electrical Manufacturers Association (“NEMA”) are disclosed. In some embodiments, a base of a housing of an enclosure assembly having a seal-receiving groove, fastener retainers, fastener walls, a moisture diverter, attachment points; and conductor pass-through apertures is disclosed. In some embodiments, a base of a housing of an enclosure assembly having a forward portion with a forward fastener retainer and forward attachment points; an aft portion of the base having an aft fastener retainer and aft and attachment points, the groove located between the forward and aft portions, a moisture diverter located between the forward and aft portions; and drainage channels encompassing the forward and aft portions is disclosed. In some embodiments, a method for pre-positioning a fastener in a housing of an enclosure assembly is disclosed.
1. An enclosure assembly, comprising:
a base enclosed by a housing formed by at least one sidewall, where
the base has an upper surface and an opposing lower surface that is located above and non-coplanar with a horizontal reference plane; and
the base includes a groove formed by a plurality of walls extending downwardly from the lower surface and configured to receive a seal, such that
placement of the seal within the groove during a mounting of the base to an installation surface prevents moisture from entering into a space formed within an inner perimeter of the groove after being mounted to the installation surface.
2. The enclosure assembly of claim 1 , wherein
the base further includes a plurality of fastener retainers, where
each one of the plurality of fastener retainers is configured with a plurality of fastener retainer flaps and a plurality of vertical guides extending upwardly from an aperture located between the upper and lower surfaces, and
the plurality of fastener retainer flaps is configured to engage threads of a fastener positioned between the plurality of vertical guides, such that
the plurality of fastener retainer flaps facilitates a prepositioning of the fastener vertically and statically between the plurality of vertical guides prior to the base being positioned on the installation surface for mounting.
3. The enclosure assembly of claim 1 , wherein
the base further includes a plurality of fastener cavities, where
each one of the plurality of fastener cavities extends downwardly from the lower surface and is configured to receive a sealant prior to the base being mounted to the installation surface, such that
the sealant prevents moisture incursion where the fastener penetrates the installation surface.
4. The enclosure assembly of claim 1 , wherein the base further includes at least one aperture located within the inner perimeter of the groove and configured to facilitate a passing through of at least one conductor between the upper and lower surfaces.
5. The enclosure assembly of claim 4 , wherein the base further includes a moisture diverter extending upwardly from the upper surface and configured to divert moisture within the housing outwardly and away from the at least one aperture when a forward end of the housing is mounted on an installation surface above an aft end of the housing.
6. The enclosure assembly of claim 1 , wherein
the base further includes at least one drainage channel, where
each drainage channel has an inner wall and an outer wall, where
an outer surface of the inner wall extends outwardly away from the lower surface of the base and downwardly to the horizontal reference plane, and
an outer surface of the outer wall extends outwardly away from the horizontal reference plane and upwardly until the outer wall reaches at least a reference plane extending through and coplanar with the upper surface of the base.
7. The enclosure assembly of claim 1 , wherein flashing extends outwardly from the housing and along the horizontal reference plane.
