<p>A system for installing and properly positioning a sub-panel mounting board (49) within a freestanding electrical enclosure, wherein the base sections (19, 21, 23, 25) of the enclosure frame (1) form a continuous rectangular guide channel (47) around the inner periphery of the enclosure which is designed to receive channel followers (51, 52) that are connected to opposite lower corners of the mounting board (49). Each channel follower (51, 52) has a depending leg (63) which extends into its respective channel segment (39). The depending leg (63) of each channel follower (51, 52) engages the bottom of the channel (45) when the mounting board (49) is tilted forward for installation within the enclosure. Once the mounting board (49) is installed and positioned upright, each channel follower (51, 52) rests upon a mounting flange and is secured thereto. Each channel follower (51, 52) further includes a depending locking lug (79). When the channel follower (51, 52) is in its rearmost position within the channel segment the mounting board (49) is automatically locked in place by the locking lug (79), thereby preventing any movement thereof.</p> |
