Cable types
Cable sizing is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at 40 °C
(104 °F) ambient temperature. Not more than three current-carrying conductors in raceway or cable or
earth (directly buried). For other conditions, dimension the cables according to local safety regulations,
appropriate input voltage and the load current of the drive.
Cable Entries
Input, motor and brake resistor cable terminal sizes (per phase) and tightening
torques are given below
. For units without enclosure extension, one hole cable lugs
(1/2 inch diameter) can be used. The maximum allowed width of the cable lug is 1.5
inches. For units with enclosure extension, two hole cable lugs (1/2 inch diameter)
can be used.
