Planning the electrical installation57Typical power cable sizesThe table below gives copper and aluminium cable types with concentric coppershield for the drives with nominal current. See also Terminal and lead-through datafor the power cables on page 129.1) The cable sizing is based on max. 9 cables laid on a cable ladder side by side, three ladder typetrays one on top of the other, ambient temperature 30 °C (86 °F), PVC insulation, surfacetemperature 70 °C (158 °F) (EN 60204-1 and IEC 60364-5-52). For other conditions, dimension thecables according to local safety regulations, appropriate input voltage and the load current of thedrive.2) The cable sizing is based on NEC Table 310-16 for copper wires, 75 °C (167 °F) wire insulation at40 °C (104 °F) ambient temperature. Not more than three current-carrying conductors in raceway orcable or earth (directly buried). For other conditions, dimension the cables according to local safetyregulations, appropriate input voltage and the load current of the drive.Drive typeACS850-04IEC 1) US 2)Cu cable type Al cable type Cu cable type Al cable typemm 2 mm 2 AWG/kcmil AWG/kcmil-387A-5 2 × (3×120) 3 × (3×120) 2 × 250 MCM 2 × 350 MCM-500A-5 3 × (3×95) 3 × (3×150) 2 × 500 MCM or 3 × 250 MCM 2 × 600 MCM or 3 × 300 MCM-580A-5 3 × (3×120) 3 × (3×185) 2 × 500 MCM or 3 × 250 MCM 2 × 700 MCM or 3 × 350 MCM-650A-5 3 × (3×150) 3 × (3×240) 2 × 600 MCM or 3 × 300 MCM 3 × 400 MCM or 4 × 250 MCM-710A-5 3 × (3×185) 4 × (3×185) 2 × 700 MCM or 3 × 350 MCM 3 × 500 MCM or 4 × 300 MCM-807A-5 3 × (3×240) 4 × (3×240) 3 × 500 MCM or 4 × 300 MCM 3 × 600 MCM or 4 × 400 MCM-875A-5 3 × (3×240) 4 × (3×240) 3 × 500 MCM or 4 × 300 MCM 3 × 700 MCM or 4 × 500 MCM3BFA 01051905 D
