Electrical circuit apparatus with fuse access section

A power distribution unit of the type mountable on an electronic equipment rack having a front side opposite a back side and transverse sides extending intermediate the front side and back side, the power distribution unit comprising in combination:

• A. a power distribution unit housing having (i) a power distribution output face opposite a rear housing wall and (ii) a side housing wall providing a fuse access section transverse to the power distribution output face;
• B. a power inlet penetrating the power distribution unit housing;
• C. a plurality of power outputs displaced along the power distribution outlet face;
• D. at least one fuse mounting assembly connected to at least one of said power outputs and mounted within said power distribution unit housing adjacent the fuse access section;
• E. at least one fuse access passage penetrating the fuse access section in the side wall of the power distribution unit housing, said fuse access passage being adjacent and in registration with said fuse mounting assembly;
• and
• F. at least one fuse access window mounted over said fuse access passage;
• whereby, when the power distribution unit housing is mounted within an electronic equipment rack with said rear housing wall facing a transverse side of the electronic equipment rack, at least a portion of a fuse mounted within said fuse mounting assembly may be observed through the fuse access window from the back side of the rack.

A power distribution unit of the type mountable on an electronic equipment rack having a front side opposite a back side and transverse sides extending intermediate the front side and back side, the power distribution unit comprising in combination:

• A. a power distribution unit housing having (i) a power distribution output face opposite a rear housing wall and (ii) a side housing wall having an indicator section transverse to the power distribution output face;
• B. at least one power inlet penetrating the power distribution unit housing;
• C. a plurality of power outputs displaced along the power distribution outlet face;
• D. a first circuit breaking device mounted within the housing disposed within a circuit intermediate the power inlet and at least one among the plurality of power outputs;
• and
• E. at least a first circuit break indicator mounted in the indicator section of the power distribution unit housing and being in communication with at least said first circuit breaking device;
• whereby, when the power distribution housing is mounted within an electronic equipment rack with said rear housing wall facing a transverse side of the electronic equipment rack, said circuit break indicator may be observed from the back side of the rack.

An electronic equipment rack assembly of the type useable to receive a polyphase power input and to provide a plurality of single phase outputs for rack mounted components, the electronic equipment rack assembly comprising in combination:

• A an electronic equipment rack providing an electronic component mounting area;
• B. a power distribution unit comprising a housing section mounted within the electronic equipment rack;
• a plurality of phase banks of outputs with each said phase bank coupled to at least one input phase from the polyphase power input;
• and a plurality of fuse assemblies mounted with the housing with each said fuse assembly connected to a corresponding phase bank, said housing having at least one fuse passage in registration with said at least one fuse assembly, each said fuse passage having a removable cover mounted to the housing section.
