from these unit blocks, along with load wiring through
Size 3, to master terminal blocks located at the top o
bottom of the structure. See Figure 16. Master terminal
blocks can be either fixed or drawout mounted. In the
drawout design the terminal blocks are rack mounted t
permit withdrawal of the entire assembly for ease o wir-
ing during installation and maintenance. Bring field wir-
ing from the horizontal wireway to the master terminal
blocks except for load wiring larger than Size 3. These
latter load wires should be carried into the vertical
wireway and under the bottom right-hand side of the uni
