Power Terminals:
Line and Load terminals are bus tabs with pre-drilled holes (see Table 3). Use of appropriate compression or
mechanical lugs for wire connection to these bus tabs is required or highly recommended. For convenience
only, some sizes (as indicated below) come with saddle clamps that can be used directly on stranded wire
without additional lugs, but may not be suitable if larger conductors are needed for voltage drop reduction.
Suggested wire sizes and tightening torques shown in the chart below are for reference when using 75
°
C rated
conductors. Always consult local codes and industry standard practices for proper wires sizes to accommodate
voltage drop and ambient conditions.
