A power distribution unit may be provided with one or more input cord assemblies that allow an input cord to be swiveled such that the cord exits an outside plane of the power distribution unit at a different angle. Such an assembly allows a power distribution unit to be placed in an equipment rack and coupled with an input power source in a flexible and convenient manner. Clearances and dimensions of equipment racks may be modified to provide enhanced space usage, efficiency, and/or density in a facility. ## Claims ### Claim 1 A power input assembly apparatus, comprising: a housing comprising an opening therethrough; a rotational member located within the housing and rotatably secured to the housing; one or more inserts coupled with the rotational member to reduce an effective width of the rotational member; and a power input cord extending through the opening and coupled with the rotational member; wherein the rotational member is configured to be rotatable into two or more different orientations relative to a longitudinal axis of the housing and thereby allow the power input cord to exit the housing at two or more different angles. ### Claim 2 (depends on 1) The apparatus of claim 1, further comprising: a locking mechanism configured to secure the rotational member at one of two or more different orientations within the housing. ### Claim 3 (depends on 2) The apparatus of claim 2, wherein the locking mechanism comprises a latch that may be secured with the rotational member. ### Claim 4 (depends on 1) The apparatus of claim 1, further comprising: a barrier located at a first end of the housing adjacent to other portions of a power distribution unit, the barrier configured to prevent passage of objects or materials through the first end. ### Claim 5 (depends on 1) The apparatus of claim 1, wherein an exit point of the power input cord from the rotational member is oriented such that it minimizes movement of conductors within a power distribution unit. ### Claim 6 (depends on 1) The apparatus of claim 1, wherein the rotational member serves as a strain relief device for the power input cord. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein the housing is a component of a power distribution unit. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the power input cord comprises a polyphase power input cord. ### Claim 9 (depends on 1) The apparatus of claim 1, wherein the rotational member is a multi-piece assembly. ### Claim 10 A method for assembling a power distribution unit, comprising: providing a housing comprising an opening therethrough; rotatably securing a rotational member within the housing; inserting one or more shims into the rotational member to reduce an effective width of the rotational member to accommodate a selected power cord diameter; and securing a power cord within the housing and coupling the power cord with the rotational member, wherein, when secured within the housing, the power input cord extends through the opening; and wherein the rotational member is configured to be rotatable into two or more different orientations relative to a longitudinal axis of the housing and thereby allow the power input cord to exit the housing at two or more different angles. ### Claim 11 (depends on 10) The method of claim 10, further comprising: coupling a locking mechanism with the housing and with the rotational member, the locking mechanism configured to secure the rotational member at one of two or more different orientations within the housing. ### Claim 12 (depends on 11) The method of claim 11, wherein the locking mechanism comprises a latch that may be secured with the rotational member. ### Claim 13 (depends on 10) The method of claim 10, further comprising: securing a barrier at a first end of the housing adjacent to other portions of a power distribution unit, the barrier configured to prevent passage of objects or materials through the first end. ### Claim 14 (depends on 10) The method of claim 10, wherein the rotational member apparatus serves as a strain relief device for the power input cord. ### Claim 15 A power distribution apparatus connectable to one or more electrical loads in an electrical equipment rack, comprising: an elongate housing extending along a longitudinal axis, the housing comprising a power input cord opening in an end portion of the housing; a rotational member rotatably secured to the housing proximate the power input cord opening; one or more inserts coupled with the rotational member to accommodate a selected power input cord diameter; and a power input cord extending between a proximal input portion and a distal plug portion, the proximal input portion being received in the power input cord opening and secured to the rotational member, thereby allowing the proximal input portion to project away from the housing transversely at different positions relative to the longitudinal axis of the housing. ### Claim 16 (depends on 15) The power distribution apparatus of claim 15, wherein the power input cord opening extends through at least two intersecting walls of the housing. ### Claim 17 (depends on 16) The power distribution apparatus of claim 16, wherein the proximal input portion extends in a first direction substantially aligned with the longitudinal axis of the housing in a first position, and the proximal input portion extends in a second direction substantially perpendicular to the longitudinal axis of the housing in a second position. ### Claim 18 (depends on 15) The power distribution apparatus of claim 15, further comprising: a locking mechanism configured to secure the power input cord at two or more different positions relative to the longitudinal axis of the housing. ### Claim 19 (depends on 18) The power distribution apparatus of claim 18, wherein the locking mechanism comprises a latch that is movable from an unlatched state to a latched state. ### Claim 20 (depends on 15) The power distribution apparatus of claim 15, wherein the power input cord comprises a polyphase power input cord. ### Claim 21 (depends on 16) The power distribution apparatus of claim 16, wherein one of the at least two intersecting walls is an end wall and the other of the at least two intersecting walls is a side wall.
