PE
Symmetrical shielded (or ar-
mored) cable with three
phase conductors and sym-
metrically constructed PE
conductor and a shield (or

PE
Symmetrical shielded (or ar-
mored) cable with three
phase conductors and a
shield (or armor), and separ-
ate PE conductor/cable
1)
1) A separate PE conductor is required if the conductivity of the shield (or armor) is not sufficient for the
PE use.
Alternate power cable types
Use as motor cabling and as
brake resistor 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
conduit is always recommen-
ded to minimize radio fre-
quency interference.
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
metal conduit (three phase
conductors and PE). For ex-
ample, EMT, or four-conduct-
or armored cable
