Modular construction distribution switchboard system cubicles with draw-out and fixed apparatus mounting flexibility

A distribution switchboard cubicle comprising:

• upper and lower ring channels having a generally rectangular outer planform for establishing perimeter boundaries of the cubicle;
• left and right front corner posts attached to the ring channels for forming a support skeleton for a front face of the cubicle;
• left and right rear corner posts attached to the ring channels for forming a support skeleton for a rear face of the cubicle;
• left and right intermediate posts symmetrically attached to the ring channels between the corner posts for forming in conjunction therewith and the ring channels a support skeleton for left and right sides of the cubicle;
• first and second vertically aligned, selectively reconfigurable cubicle sections defined within the cubicle, each of the cubicle sections including one of:
• a fixed mounting assembly including:
• generally identical upper and lower generally horizontally oriented mounting members, each mounting member connecting each respective pair of corner and intermediate posts on the left and right sides of the cubicle, and left and right breaker mounting angles connected to each respective pair of horizontally oriented upper and lower mounting members for mounting a first electrical apparatus thereto in a fixed, non-reciprocating manner;
• and
• a draw-out mounting assembly including:
• a draw-out cradle, left and right generally elongated rear cradle mounting angles connected generally parallel to a corresponding intermediate post and to a rear face of the draw-out cradle, and left and right front cradle mounting plates connected to a front portion of the draw-out cradle and a corresponding corner post.
