Table 4-6 Typical cable sizes for size 1 drives
Table 4-7 Auxiliary wiring for size 1 drives
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 A.52-14 (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.
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.

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 (167 °F) rated cables, 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 Mentor MP shown above. For high temperature cable
sizing, please refer to the data supplied by the manufacturer of the high temperature
cable.
