Cables And Protective Devices - Eaton PowerXL DE1 Manual

9.7 Cables and protective devices

The mains cables and motor cables must be sized as required by local
standards and by the load currents that will be involved. The rated
operational currents are specified in Page 131ff. Electric cables with
adequate insulation for the specified mains voltages must be used. The PE
conductor's conductivity must be the same as the phase conductors'
conductivity (same cross-sectional area).
In order to meet CE and C-Tick EMC requirements, a symmetrical, fully
screened (360°) motor cable must be used. It is recommended to use a four-
core cable in order to reduce the screening load resulting from leakage
currents. A screened cable is not required on the mains side.
If the device is being installed as per UL standards, UL-listed fuses and
copper cables with a temperature rating of +75 °C (167 °F) must be used.
The motor cable must be an MC cable with a continuously corrugated
aluminum armor and symmetrical protective earth conductors or – if armor is
not used – a screened power cable. The motor cable's length will depend on
the interference category.
NOTICE
When selecting fuses and cables, make sure to always comply
with all the regulations that apply at the installation site.
