ABSTRACT:
A system for installing and properly positioning a sub-panel mounting board within a freestanding electrical enclosure, wherein the base sections of the enclosure frame form a continuous rectangular guide channel around the inner periphery of the enclosure which is designed to receive in opposite parallel channel segments thereof a pair of channel followers that are connected to opposite lower corners of the mounting board. Each channel follower has a depending leg which extends into its respective channel segment and supports the mounting board during installation thereof. The depending leg of each channel follower engages the bottom of the channel when the mounting board is tilted forward for installation within the enclosure. Once the mounting board is installed and positioned upright, each channel follower rests upon a mounting flange formed by the enclosure frame, thereby allowing the mounting board to be secured thereto. Each channel follower further includes a depending locking lug which extends into the rearmost cross channel section when the mounting board is positioned such that each channel follower is in its rearmost position within the channel segment in which it travels. In such position, the mounting board is automatically locked in place by the locking lug, thereby preventing any movement thereof.
