Motor cables may enter from the top or bottom of the enclosure. In the one-high enclosure, the motor termi- nals are located on the inside lower left wall as shown in Figure 36. The incoming leads should be trained for maximum space between phases and ground. The connections may be made before or after energizing the main bus and without shutting down adjacent equip- ment. Also see Figure 60.

warning: If the main bus in energized while load cables are be- ing installed, all barriers must be in place and the disconnect

switch must be in the off position and the blades must be visu-

ally checked to ensure that they are completely disconnected from the vertical bus.

The motor terminals can accommodate up to one 500- MCM per phase with stress cones in the standard 26-inch wide enclosure. If larger cable entries are required, an optional 34inch wide cabinet is available.
