In some approaches, the power distribution housing includes a base having a main wall, a sidewall extending from the main wall, and a vent through the main wall. The vent may include a vent opening extending between an interior surface of the main wall and an exterior surface of the main wall. A plurality of passageways may be recessed into the exterior surface of the main wall, the plurality of passageways extending between the vent opening and the sidewall. The power distribution housing may further include a cover removably coupled to the base, the cover and the base defining an interior cavity operable to house at least one fusible element. ## Claims ### Claim 1 A power distribution housing, comprising: a base comprising: a main wall; a sidewall extending from the main wall; a vent through the main wall, the vent including: a vent opening extending between an interior surface of the main wall and an exterior surface of the main wall; and a plurality of passageways recessed into the exterior surface of the main wall, the plurality of passageways extending between the vent opening and the sidewall; and a cover removably coupled to the base, the cover and the base defining an interior cavity operable to house at least one fusible element. ### Claim 2 (depends on 1) The power distribution housing of claim 1, the vent further comprising a cover extending over the vent opening. ### Claim 3 (depends on 2) The power distribution housing of claim 2, wherein the cover is a waterproof and breathable cover. ### Claim 4 (depends on 2) The power distribution housing of claim 2, wherein the cover comprises a membrane coupled to an adhesive, and wherein the adhesive is directly attached to an interior perimeter face of the vent. ### Claim 5 (depends on 4) The power distribution housing of claim 4, wherein the membrane is an expanded polytetrafluoroethylene membrane. ### Claim 6 (depends on 1) The power distribution housing of claim 1, the vent further comprising at least one support component extending across the vent opening. ### Claim 7 (depends on 1) The power distribution housing of claim 1, the vent further comprising a target frame circumscribing the vent opening, wherein the target frame extends into the interior cavity from the interior surface of the main wall of the base. ### Claim 8 (depends on 1) The power distribution housing of claim 1, the plurality of passageways comprising: a first pair of passageways extending between a first side and a second side of the main wall of the base; and a second pair of passageways extending perpendicularly from the first pair of passageways, the second pair of passageways extending to a first end of the main wall of the base. ### Claim 9 (depends on 8) The power distribution housing of claim 8, the first and second pairs of passageways defining outlets through the sidewall of the base. ### Claim 10 (depends on 8) The power distribution housing of claim 8, wherein the first and second pairs of passageways and the vent opening are fluidly connected. ### Claim 11 A power distribution assembly, comprising: a power distribution housing having a base and a cover defining an interior cavity operable to house at least one fusible element, the base comprising: a main wall flush mountable on a surface; a sidewall extending from the main wall; a vent through the main wall, the vent including: a vent opening extending between an interior surface of the main wall and an exterior surface of the main wall; and a plurality of passageways recessed into the exterior surface of the main wall, the plurality of passageways extending between the vent opening and the sidewall. ### Claim 12 (depends on 11) The power distribution assembly of claim 11, the vent further comprising a cover extending over the vent opening, wherein the cover is a waterproof and breathable cover. ### Claim 13 (depends on 12) The power distribution assembly of claim 12, wherein the cover comprises an expanded polytetrafluoroethylene membrane coupled to an interior perimeter face of the vent by an adhesive. ### Claim 14 (depends on 11) The power distribution assembly of claim 11, the vent further comprising a target frame circumscribing the vent opening, wherein the target frame extends into the interior cavity from the interior surface of the main wall of the base, and wherein the vent opening includes a support component. ### Claim 15 (depends on 11) The power distribution assembly of claim 11, the plurality of passageways comprising: a first pair of passageways extending between a first side and a second side of the main wall of the base; and a second pair of passageways extending perpendicularly from the first pair of passageways, the second pair of passageways extending to a first end of the main wall of the base, wherein the first and second pairs of passageways define outlets through the sidewall of the base. ### Claim 16 A power distribution housing, comprising: a base couplable with a cover, wherein the cover and the base define an interior cavity containing at least one fusible element coupled to the base, and wherein the base comprises: a main wall; a sidewall extending from the main wall; a vent through the main wall, the vent including: a vent opening extending between an interior surface of the main wall and an exterior surface of the main wall; and a plurality of passageways recessed into the exterior surface of the main wall, the plurality of passageways extending between the vent opening and the sidewall. ### Claim 17 (depends on 16) The power distribution housing of claim 16, the vent further comprising a waterproof and breathable cover. ### Claim 18 (depends on 17) The power distribution housing of claim 17, wherein the waterproof and breathable cover comprises a membrane coupled to an adhesive, and wherein the adhesive is directly attached to an interior perimeter face of the vent. ### Claim 19 (depends on 16) The power distribution housing of claim 16, the plurality of passageways comprising: a first pair of passageways extending between a first side and a second side of the main wall of the base; and a second pair of passageways extending perpendicularly from the first pair of passageways, the second pair of passageways extending to a first end of the main wall of the base. ### Claim 20 (depends on 19) The power distribution housing of claim 19, the first and second pairs of passageways defining outlets through the sidewall of the base.
