12.2 Cable and fuse size ratings
Maximum continuous input currents are given in section 2.2
page 6 to aid the selection of fuses and cabling. The maximum input
current is dependent on the ripple content of the output current. A value
of 100% ripple has been assumed for the given ratings.
The cable sizing selected when installing a Quantum MP must comply
with the local wiring regulations. The information provided in this section
is provided for guidance purposes only.
The power terminals on the Quantum MP have been designed to
accommodate a maximum cable size of 150mm
2
(350kcmil) with a
temperature rating of 90°C (194°F).
The actual cable size depends on a number of factors including:
•
Actual maximum continuous current
•
Ambient temperature
•
Cable support, method and grouping
•
Cable voltage drop
In applications where the motor used is of a reduced rating, the cable
sizing selected can be appropriate for that motor. To protect the motor
and the output cabling the drive must be programmed with the correct
motor rated current.
When using reduced cable sizes, the branch circuit protection fuse rating
needs to be reduced in line with the cable size selected.
The following table shows typical cable sizes based on USA and
International standards, assuming 3 conductors per raceway/conduit, an
ambient temperature of 40°C (104°F) and applications with high output
current ripple content.
Table 12-9 Typical cable sizes, Quantum size 1
1.
The maximum cable size is defined by the power terminal housing
using 90°C (194°F) rated cables as per Table A.52-5 of the
standard.
2.
Assumes the use of 75°C rated cables for drives rated more than
100 A output, 60°C for drives rated less than 100 A, as per Table
310.16 of the National Electrical Code.
The use of higher temperature rated cable would allow a reduction on
the minimum recommended cable size for Quantum MP shown above.
For high temperature cable sizing, please contact the supplier of the
drive.

Notes for IEC 60364:
IEC 60364-5-52 use installation method B2, Table A.52-4 for three loaded conductors. PVC insulation 30°C and apply derating factor for 40˝C from
Table A52-14 (0.87 for PVC).
Notes for UL508C:
Either 60°C or 75°C cable can be used. Ampacities as per table 40.3 as described in the UL508C standard.
