Alternate power cable types
Use as motor cabling
Use as input power cabling
Cable type
Yes with phase conductor
smaller than 10 mm2 (8 AWG)
Cu, or motors up to 30 kW
(40 hp).
Yes with phase conductor
smaller than 10 mm2 (8 AWG)
Cu.
PVC
Four-conductor cabling in PVC
conduit or jacket (three phase
conductors and PE)
Note:
Shielded or armored
cable, or cabling in metal con-
duit is always recommended to
minimize radio frequency inter-
ference.
Yes with phase conductor
smaller than 10 mm2 (8 AWG)
Cu, or motors up to 30 kW
(40 hp)
Yes
EMT
Four-conductor cabling in met-
al conduit (three phase con-
ductors and PE), eg, EMT, or
four-conductor armored cable
Yes with motors up to 100 kW
(135 hp). A potential equaliza-
tion between the frames of mo-
tor and driven equipment is re-
quired.
Yes
Well-shielded (Al/Cu shield or
armor) four-conductor cable
(three phase conductors and
a PE)
No
Yes
PE
WARNING!
If you use unshielded
single-core cables in an
IT network, make sure
that the non-conductive
outer sheath (jacket) of
the cables have good
contact with a properly
grounded conductive sur-
face. For example, install
the cables on a properly
grounded cable tray. Oth-
erwise voltage may be-
come present on the non-
conductive outer sheath
of the cables, and there
is even a risk of an elec-
tric shock.
A single-core cable system:
three phase conductors and
PE conductor on cable tray
