DETAILED DESCRIPTION
[0020] Referring now to Figures 1-4, an electrical distribution device 100 with an improved cabling device 104 installed is shown. The electrical distribution device 100 includes a frame 108 having uprights 112 and opposed side walls 116, a line bus section 120, a main breaker/fused switch 124, a load bus section 128 and a through bus section 132. When these particular sections are assembled they form a switchboard main section 136.
[0021] As shown in the frontal view depicted in Figure 1 , access to a cabling area 140 (Figure 2) located behind the main breaker/fused switch 124, load bus section 128 and through bus section 132 is restricted. In the cabling area 140 cables (not shown) from the utility supplying power to the switchboard main section 136 are pulled from raceways or conduit in the floor, walls or ceiling and connected to the cable lugs 144 (Figure 2) attached to line bus busbars 148. The line bus section 120 is securely attached to the opposed side walls 116 by line bus brackets 152 and a line bus subframe 156. The main breaker/fused switch 124, load bus section 128 and through bus section 132 are attached to a rotatable section 160 of improved cabling device 104.
[0022] The improved cabling device 104 includes a first fixed section 164 and a second fixed section 168, which can be temporally attached to the opposed side walls 116 by L-shaped slots 172 which receive a double headed rivet 176 and securely attached to the side walls 116 by screws 196. The first fixed section 164 is securely attached to one of the opposed side walls 116 along one side and attached by a hinge 180 to the rotatable section 160 along its other side.
[0023] In some applications the hinge 180, or other known mechanisms for permitting rotation of an attached device, could also be attached to a structural member of the frame 108, such as one of the uprights 112 or the side walls 116. The second fixed section 168 is securely attached to the other of the opposed side walls 116.
[0024] When cabling is required the main breaker/fused switch 124 is electrically disconnected from the line bus busbars 148 and the through bus section 132 is electrically disconnected from any adjacent through bus sections 132. After the main breaker/fused switch 124 through bus section 132 have been disconnected a pivotal latch 184 (Figure 3) engaging the second fixed section 168 must be released to allow rotation of the rotatable section 160. Additionally, as shown in Figure 3, the improved cabling device 104 includes a structural support member 190, positioned below the first fixed section 164. Generally, the structural support member 190 provides load bearing support for the rotatable section 160 and, for example, can assist in preventing the rotatable section 160 from sagging during rotation. [0025] When the rotatable section 160 starts rotating the other end of the pivotal latch 184 enters a hole 188 in the first fixed section 164. When the rotatable section 160 has rotated about 90 degrees a notch 192 in the pivotal latch 184 engages an edge of the hole 188 in the first fixed section 164 to keep the rotatable section 160 from moving while cabling is being done.
[0026] In the preceding, reference is made to various embodiments. However, the scope of the present disclosure is not limited to the specific described embodiments. Instead, any combination of the described features and elements, whether related to different embodiments or not, is contemplated to implement and practice contemplated embodiments. Furthermore, although embodiments may achieve advantages over other possible solutions or over the prior art, whether or not a particular advantage is achieved by a given embodiment is not limiting of the scope of the present disclosure. Thus, the preceding aspects, features, embodiments and advantages are merely illustrative and are not considered elements or limitations of the appended claims except where explicitly recited in a claim(s).
[0027] It is to be understood that the above description is intended to be illustrative, and not restrictive. Many other implementation examples are apparent upon reading and understanding the above description. Although the disclosure describes specific examples, it is recognized that the systems and methods of the disclosure are not limited to the examples described herein but may be practiced with modifications within the scope of the appended claims. Accordingly, the specification and drawings are to be regarded in an illustrative sense rather than a restrictive sense. The scope of the disclosure should, therefore, be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled.
